| 1 | Theoretical Progress and Key Technologies of Onshore Ultra-Deep Oil/Gas Exploration显示文摘Oil/gas exploration around the world has extended into deep and ultra-deep strata because it is increasingly difficult to find new large-scale oil/gas reservoirs in shallow–middle buried strata. In recent years, China has made remarkable achievements in oil/gas exploration in ultra-deep areas including carbonate and clastic reservoirs. Some (ultra) large-scale oil and gas fields have been discovered. The oil/gas accumulation mechanisms and key technologies of oil/gas reservoir exploration and development are summarized in this study in order to share China’s experiences. Ultra-deep oil/gas originates from numerous sources of hydrocarbons and multiphase charging. Liquid hydrocarbons can form in ultradeep layers due to low geothermal gradients or overpressures, and the natural gas composition in ultra-deep areas is complicated by the reactions between deep hydrocarbons, water, and rock or by the addition of mantle- or crust-sourced gases. These oils/gases are mainly stored in the original highenergy reef/shoal complexes or in sand body sediments. They usually have high original porosity. Secondary pores are often developed by dissolution, dolomitization, and fracturing in the late stage. The early pores have been preserved by retentive diageneses such as the early charging of hydrocarbons. Oil/gas accumulation in ultra-deep areas generally has the characteristics of near-source accumulation and sustained preservation. The effective exploration and development of ultra-deep oil/gas reservoirs depend on the support of key technologies. Use of the latest technologies such as seismic signal acquisition and processing, low porosity and permeability zone prediction, and gas–water identification has enabled the discovery of ultra-deep oil/gas resources. In addition, advanced technologies for drilling, completion, and oil/gas testing have ensured the effective development of these fields. | Xusheng Guo Dongfeng Hu Yuping Li Jinbao Duan Xuefeng Zhang Xiaojun Fan Hua Duan Wencheng Li | 2019 | Engineering2019,5,3: | 15 |
| 2 | Community structure of macrobenthos in coastal water off Rushan, southern Shandong Peninsula, and the relationships with environmental factors显示文摘To understand the present actuality of the marine ecosystem in the southern coastal water region of the Shandong Peninsula and the impact of the global change and the human activities to the marine ecosystem of the region, the macrobenthic community structure was researched based on data from 26 sampling stations carried out on four seasonal cruises from December 2006 to November 2007. The data was analyzed using PRIMER 6.0 and SPSS 15.0 software packages. The results showed that 236 macrobenthic species in total were collected from the research region by the field works. Most of the species belong to Polychaeta (76 species), Mollusca (75) and Crustacea (60). Of which, 33 species were common species by the four cruises. The dominant species were different among the four seasons, however, the polychaete species Nephtys oligobranchia and Sternaspis scutata were always dominant in the four seasons. The abundances and biomasses of the macrobenthos from the research region were variable in the four seasons. The results of CLUSTER and MDS analysis showed that the similarities of macrobenthic structures among the stations were low, most of the similarities were at about 40% of similarity values, only that of two stations were up to 60%. In accordance with the similarity values of the macrobenthic structures, the 26 stations were clustered as six groups at arbitrary similarity level of 30%. The ABC curve indicated that the marcofauna communities in the research region had not been disturbed distinctly. The results of BIOENV and BVSTEP (Spearman) analysis implied that the concentrations of organic matter in bottom water and heavy metal copper in sediment, water depth and temperature of bottom were the most significant environmental factors to affect the macrobentic community. | LI Xinzheng LI Baoquan WANG Hongfa WANG Jinbao WANG Xiaochen ZHOU Jin HAN Qingxi MA Lin DONG Chao ZHANG Baolin | 2009 | Acta Oceanologica Sinica2009,28,5: | 14 |
| 3 | Zircon LA-ICPMS study and petrogenesis simulation of Dahuabei pluton in the Wulashan area,Inner Mongolia显示文摘Dahuabei pluton in the Wulashan area,Inner Mongolia,is an alkaline and peraluminous granitic pluton.LA-ICPMS U-Pb dating of zircons indicates that this pluton crystallized at 330±10 Myr.The pluton did not experience apparent zircon fractionation.The consistent temperatures between Zr saturation(765℃) and the average zircon-rutile Ti equilibrium(780℃),together with zircon ages and their CL images,indicated that there were no inherited zircons in this pluton.Through the simulation of the dry-system crystallization process of magma cooling at 200 MPa and 1100-709℃,the phase diagram and composition evolution tendency of different phases were obtained.The magma reached its liquidus at 1069℃.Sanidine was the first crystallized phase;at 709℃the residual magma was less than 4%,and the range of 1069-719℃should be the most suitable approach to the real condition.It is shown that at least some part of the pluton underwent such isobaric equilibrium crystallization processes during its crystallization. | Dapeng Li Yuelong Chen Liemeng Chen Zhong Wang Jinbao Liu | 2009 | Progress in Natural Science:Materials International2009,19,12: | 11 |
| 4 | The application of nanostructured transition metal sulfides as anodes for lithium ion batteries显示文摘With wide application of electric vehicles and large-scale in energy storage systems, the requirement of secondary batteries with higher power density and better safety gets urgent. Owing to the merits of high theoretical capacity, relatively low cost and suitable discharge voltage, much attention has been paid to the transition metal sulfides. Recently, a large amount of research papers have reported about the application of transition metal sulfides in lithium ion batteries. However, the practical application of transition metal sulfides is still impeded by their fast capacity fading and poor rate performance. More well-focused researches should be operated towards the commercialization of transition metal sulfides in lithium ion batteries. In this review, recent development of using transition metal sulfides such as copper sulfides,molybdenum sulfides, cobalt sulfides, and iron sulfides as electrode materials for lithium ion batteries is presented. In addition, the electrochemical reaction mechanisms and synthetic strategy of transition metal sulfides are briefly summarized. The critical issues, challenges, and perspectives providing a further understanding of the associated electrochemical processes are also discussed. | Jinbao Zhao Yiyong Zhang Yunhui Wang He Li Yueying Peng | 2018 | Journal of Energy Chemistry2018,27,6: | 7 |
| 5 | Characteristics of global cerebral ischemia models constructed by modified four-vessel occlusion in rats显示文摘BACKGROUND: Pulsinelli et al developed a kind of rat models with four-vessel occlusion-induced global cerebral ischemia. Because the histo-pathological changes and severe cerebral ischemia reproducibility of this model are good and the stability of this model in circulation respiration is superior to that of other models, so four-vessel occlusion method has become a classic modeling method for global cerebral ischemia model. This model has been improved in some laboratories to meet different requirements in different studies. OBJECTIVE: To establish a highly reproducible rat model of reversible forebrain ischemia by modifying four-vessel occlusion model introduced by Pulsinelli et al, and to investigate its neurophysiological and pathological changes and the characteristics of modified operation. DESIGN:Completely randomized grouping, controlled trial. SETTING:Department of Anesthesiology,Changhai Hospital, Second Military Medical University of Chinese PLA. MATERIALS: A total of 65 male healthy SD rats, weighing 250-300 g, were provided by the Experimental Animal Center of Second Military Medical University of Chinese PLA. VSM hemodynamic monitor and temperature monitor (Thermal ert TH-5,U.S.A) were used. METHODS: The trial was conducted in the Department of Anesthesiology, Changhai Hospital, Second Military Medical University of Chinese PLA from January 2005 to March 2006. ① Experimental grouping: Sixty-five rats were randomly divided into the following 7 groups: sham-operation group (n =9): given the same operation, without occlusion of vessels; 5 minutes ischemia group (n =9): ischemia 5 minutes and reperfusion 72 hours; 10 minutes ischemia group (n =8): ischemia 10 minutes and reperfusion 72 hours; 15 minutes ischemia group (n =9): ischemia 15 minutes and reperfusion 72 hours; 20 minutes ischemia group (n =8): ischemia 20 minutes and reperfusion 72 hours; 30 minutes ischemia group (n =7); ischemia 30 minutes and reperfusion 72 hours; ischemia control group (n =15): ischemia 15 minutes and reperfusion 180 minutes. ② Preparation of the model of global cerebral ischemia: Four-vessel occlusion- induced global cerebral ischemia rat models were modified, i.e. bilateral vertebral arteries could be electrocauterized and blocked, and bilateral common carotid arteries were enclosed with 10-0 suture loosely. On the second day, keeping the animal awake, the suture was tightened and kept tense to block the blood flow of bilateral common carotid artery. After certain duration of ischemia, the suture was cut off and drawn out, thus the reperfusion of bilateral common carotid artery was resumed. ③Observation of physiological indexes: VSM hemodynamic monitor and temperature monitor (Thermal ert TH-5,U.S.A) were used to record and measure the changes of blood pressure, rectal temperature, brain temperature ,arterial blood gas and other physiological indexes of the rats in the control group before, 5 and 15 minutes after ischemia and 10,30,60,120 and 180 minutes after reperfusion. ④Preparation of brain tissue pathological samples: Except for ischemia control group, rats of other groups were anesthetized and their brain tissues were harvested and subjected to haematoxylin and eosin staining at 72 hours after reperfusion. ⑤Evaluation of pathological change of brain tissue: The coronal plane of anterior commissure of cerebrum was used to evaluate corpora striatum, and the coronal plane of anterior hippocampus was used to evaluate hippocampal CA1/2 region, CA3 region and CA4 region, subiculum, superior pyramidal lobe and inferior pyramidal lobe of dentate gyrus as well as neocortex. Irreversible neuronal damage included pyknotic cells with eosinophilic cytoplasm and trachychromatic nucleus, homogenous cytoplasm and naked nucleus. Neurons without the above changes were considered to be normal. The number of normal neurons in the above-mentioned brain regions was counted under the microscope. MAIN OUTCOME MEASURES:① The changes of blood pressure, rectal temperature, brain temperature, arterial blood gas and other physiological indexes of rats before, 5 and 15 minutes after ischemia and 10,30,60,120 and 182 minutes after reperfusion. ②The number of normal neurons in hippocampal CA1/2 region, CA3 region, CA4 region, subiculum, superior pyramidal lobe and inferior pyramidal lobe of dentate gyrus as well as neocortex at 72 hours of ischemia. RESULTS: Sixty-five SD rats were involved in the result analysis. ①Changes in the physiological indexes of rats during cerebral ischemia/reperfusion: Changes in arterial blood pressure: arterial blood pressure at 5 minutes after ischemia was significantly higher than that before ischemia [(132.82±12.38) mm Hg vs. (118.58±5.85) mm Hg,1 mm Hg=0.133 kPa, P < 0.01], and there was no significant difference in arterial blood pressure between at ischemia 15 minutes, reperfusion 10,30,60,120 and 180 minutes and before ischemia (P > 0.05); Changes in arterial blood gas: pH value at 15 minutes after ischemia was significantly higher than that before ischemia (7.56±0.05 vs. 7.47±0.09,P < 0.01), PaO2 value at 15 minutes after ischemia was significantly higher than that beischemia [(1.71±0.04) kPa vs. (1.56±0.08) kPa, P < 0.01], and PaCO2 value at 5 and 15 minutes after ischemia was significantly lower than that before ischemia [(0.44±0.04),(0.37±0.04),(0.57±0.04) kPa,P < 0.01];Changes in rectal temperature and brain temperature: Brain temperature at 5 and 10 minutes after ischemia and at 10 and 30 minutes after reperfusion was significantly lower than that before ischemia [(37.01±0.43),(36.44±0.35),(36.81±0.45),(37.23±0.24),(37.74±0.28) ℃,P < 0.01], and rectal temperature at 10 minutes after reperfusion was significantly lower than that before ischemia [(36.76±0.21),(37.37±0.19) ℃,P < 0.01]. ② Changes in the normal neurons in different encephalic regions of rats at different time after ischemia and 72 hours after reperfusion: At 5,10,15,20 and 30 minutes after ischemia, the number of normal neurons in subiculum was 86%,73%,11%,8%,6% of that in the sham-operation, respectively (P < 0.05-0.01), the number of normal neurons in internal segment of hippocampal CA1/2 region was 74%,53%,8%,5%,5% of that in the sham-operation group (P < 0.01),the number of normal neurons in middle segment of hippocampal CA1/2 was 73%,48%,11%,8%,6% of that in the sham-operation group, respectively (P < 0.01),and the number of normal neurons in external segment of hippocampal CA1/2 region was 90%,72%,37%,31%,22% of that in the sham-operation group, respectively (P < 0.01); At 10,15,20 and 30 minutes after ischemia, the number of normal neurons in hippocampal CA3 region was 80%,67%,47%,40% of that in the sham-operation group respectively (P < 0.01), the number of normal neurons in hippocampal CA4 region was 79%,70%,60%,43% of that in the sham-operation group , respectively (P < 0.01) and the number of normal neurons in superior pyramidal lobe of dentate gyrus was 85%,75%,59%,52% of that in the sham-operation group, respectively (P < 0.05,0.01).

CONCLUSION: To construct cerebral ischemia rat model with modified four-vessel occlusion can cause severe cerebral ischemia.It has a few influences on arterial blood pressure and arterial blood gas of model rat and is easy for blocking and opening carotid artery system. | Jinbao Li Lai Jiang Hua Xu Yuanchang Xiong Xiaoming Deng | 2006 | Neural Regeneration Research2006,1,5: | 7 |
| 6 | Effect of Stokes drift on upper ocean mixing显示文摘Stokes drift is the main source of vertical vorticity in the ocean mixed layer. In the ways of Coriolis-Stokes forcing and Langmuir circulations, Stokes drift can substantially affect the whole mixed layer. A modified Mellor-Yamada 2.5 level turbulence closure model is used to parameterize its effect on upper ocean mixing conventionally. Results show that comparing surface heating with wave breaking, Stokes drift plays the most important role in the entire ocean mixed layer, especially in the subsurface layer. As expected, Stokes drift elevates both the dissipation rate and the turbulence energy in the upper ocean mixing. Also, influence of the surface heating, wave breaking and wind speed on Stokes drift is investigated respectively. Research shows that it is significant and important to assessing the Stokes drift into ocean mixed layer studying. The laboratory observations are supporting numerical experiments quantitatively. | LI Shuang SONG Jinbao SUN Qun | 2008 | Acta Oceanologica Sinica2008,27,2: | 7 |
| 7 | Effect of Langmuir circulation on upper ocean mixing in the South China Sea显示文摘Effect of Langmuir circulation(LC) on upper ocean mixing is investigated by a two-way wave-current coupled model.The model is coupled of the ocean circulation model ROMS(regional ocean modeling system) to the surface wave model SWAN(simulating waves nearshore) via the model-coupling toolkit.The LC already certified its importance by many one-dimensional(1D) research and mechanism analysis work.This work focuses on inducing LC's effect in a three-dimensional(3-D) model and applying it to real field modeling.In ROMS,the Mellor-Yamada turbulence closure mixing scheme is modified by including LC's effect.The SWAN imports bathymetry,free surface and current information from the ROMS while exports significant wave parameters to the ROMS for Stokes wave computing every 6 s.This coupled model is applied to the South China Sea(SCS) during September 2008 cruise.The results show that LC increasing turbulence and deepening mixed layer depth(MLD) at order of O(10 m) in most of the areas,especially in the north part of SCS where most of our measurements operated.The coupled model further includes wave breaking which will brings more energy into water.When LC works together with wave breaking,more energy is transferred into deep layer and accelerates the MLD deepening.In the north part of the SCS,their effects are more obvious.This is consistent with big wind event in the area of the Zhujiang River Delta.The shallow water depth as another reason makes them easy to influence the ocean mixing as well. | LI Shuang SONG Jinbao FAN Wei | 2013 | Acta Oceanologica Sinica2013,32,3: | 6 |
| 8 | The geometric factor of high energy protons detector on FY-3 satellite显示文摘Geometric factor is the key parameter for inversion of particle spectrum in space particle detection. Traditional geometric factor is obtained through the method of numerical calculation with the actual structure of the detector as the input condition. The degree of accuracy for data inversion is reduced since traditional geometric factor fails to take into account the physical process of interaction between the particle and substance as well as the influence of factors such as the particle interference between different energy channels on the measurement result. Here we propose an improved geometrical factor calculation method, the concept of which is to conduct actual structural modelling of the detector in the GEANT4 program, consider the process of interaction between the particle and substance, obtain the response function of the detector to particles of different energy channels through the method of Monte Carlo simulation, calculate the influence of contaminated particle on the geometrical factor, and finally get the geometrical factors for different energy channels of the detector. The imrpoved geometrical factor obtained through the method has carried out inversion for the data of high energy protons detector on China's FY-3 satellite, the energy spectrum after which is more in line with the power law distribution recognized by space physics. The comparison with the measured result of POES satellite indicates that the FY-3 satellite data are in good accordance with the satellite data, which shows the method may effectively improve the quality of data inversion. | ZHANG ShenYi ZHANG XianGuo WANG ChuiQin SHEN GuoHong JIN Tao ZHANG BinQuan SUN YueQiang ZHU GuangWu LIANG JinBao ZHANG XiaoXin LI JiaWei HUANG Cong HAN Ying | 2014 | Science China Earth Sciences2014,57,10: | 6 |
| 9 | Geochronology and Hf Isotopes of Granite Gravel from Fanjingshan, South China: Implication for the Precambrian Tectonic Evolution of Western Jiangnan Orogen显示文摘The debate of assembly time between the Yangtze and Cathaysia blocks has aroused the disputation on the formation mechanism of Jiangnan orogen, South China. Therefore widespread magmatism of 830–750 Ma in South China is interpreted as the product of either plume or arc magmatism, which results in distinctive depositional background in the Neoproterozoic. Granite gravel located at the unconformity between the Banxi Group and Fanjingshan Group of the western Jiangnan orogen was collected, which gave a new age limit to the deposition of the Banxi Group and Nanhu rift. Zircons from the granite gravel crystallized yield a weighted mean 206Pb/238U age of 789±11 Ma, which probably represents the end of the Jiangnan orogeny and marks the onset of Nanhua rift. These zircons have negative εHf(t) of-2.1 to-6.0, with TDM of 1.38–1.52 Ga and Tcrust of 1.81–1.98 Ga indicating an old continental crust origin for the granite. | Jinbao Su Yueqiao Zhang Shuwen Dong Xuanhua Chen Yong Li Jianjun Cui | 2014 | Journal of Earth Science2014,25,4: | 6 |
| 10 | Two centuries of April-July temperature change in southeastern China and its influence on grain productivity显示文摘China is a traditional agriculture based country and one main region for crop production is southeastern China where temperature is a dominant climate variable affecting agriculture. Temperature and social disturbances both influence crop production, yet distinguishing their relative impacts is difficult due to a lack of reliable, high-resolution historical climatic records before the very recent period. Here we present the first tree-ring based warm-season temperature reconstruction for southeastern China, a core region of the East Asian monsoon, for the past 227 years. The reconstruction target was April-July mean temperature, and our model explained 60.6% of the observed temperature variance during 1953–2012.Spatial correlation analysis showed that the reconstruction is representative of April-July temperature change over most of eastern China. The reconstructed temperature series agrees well with China-scale(heavily weighted in eastern China) agricultural production index values quite well at decadal timescales.The impacts of social upheavals on food production, such as those in the period 1920–1949, were confirmed after climatic influences were excluded. Our study should help distinguish the influence of social disturbance and warm-season temperature on grain productivity in the core agricultural region of China during the past two centuries. | Jiangfeng Shi Jinbao Li David D.Zhang Jingyun Zheng Shiyuan Shi Quansheng Ge Harry F.Lee Yesi Zhao Jie Zhang Huayu Lu | 2017 | Science Bulletin2017,62,1: | 6 |
| 11 | A numerical study on seasonal variations of the thermocline in the South China Sea based on the ROMS显示文摘On the basis of the regional ocean modeling system(ROMS), the seasonal variations of the thermocline in the South China Sea(SCS) were numerically investigated. The simulated hydrodynamics are in accordance with previous studies: the circulation pattern in the SCS is cyclonic in winter and anticyclonic in summer, and such a change is mostly driven by the monsoon winds. The errors between the modeled temperature profiles and the observations obtained by cruises are quite small in the upper layers of the ocean, indicating that the ocean status is reasonably simulated. On the basis of the shapes of the vertical temperature profiles, five thermocline types(shallow thermocline, deep thermocline, hybrid thermocline, double thermocline, and multiple thermocline) are defined herein. In winter, when the northeasterly monsoon prevails, most shallow shelf seas in the northwest of the SCS are well mixed, and there is no obvious thermocline. The deep region generally has a deep thermocline, and the hybrid or double thermocline often occurs in the areas near the cold eddy in the south of the SCS. In summer, when the southwesterly monsoon prevails, the shelf sea area with a shallow thermocline greatly expands. The distribution of different thermocline types shows a relationship with ocean bathymetry: from shallow to deep waters, the thermocline types generally change from shallow or hybrid to deep thermocline, and the double or multiple thermocline usually occurs in the steep regions. The seasonal variations of the three major thermocline characteristics(the upper bound depth, thickness, and intensity) are also discussed. Since the SCS is also an area where tropical cyclones frequently occur, the response of thermocline to a typhoon process in a short time scale is also analyzed. | FAN Wei SONG Jinbao LI Shuang | 2014 | Acta Oceanologica Sinica2014,33,7: | 6 |
| 12 | Preparation of Highly Crystalline Microcrystalline Cellulose by Hydrolysis of Cellulose with Phosphotungstic Acid显示文摘Phosphotungstic acid(H_3PW_(12)O_(40), HPW), a kind of solid acid, is widely used for hydrolyzing cellulose to prepare microcrystalline cellulose(MCC). MCC is usually used in food, synthetic leather, chemical and pharmaceutical industries. The use of response surface methodology(RSM)can help avoid the random error caused by single factor experimental design,reduce test times and cost, and improve quality. The RSM was used in this study to determine the following optimal process conditions: H^+ molar quantity, 31 mmol/L; reaction temperature, 93℃; reaction time, 2 h; and solid to liquid ratio, 1∶38. Under these conditions, the crystallinity of MCC was77.4%. Thus, the use of RSM allows the preparation of MCC with higher performance and increased crystallinity. | Jing Wang JinBao Li MeiYun Zhang ShunXi Song DanDan Qiang | 2018 | Paper And Biomaterials2018,3,1: | 5 |
| 13 | Using Geochemistry of Rare Earth Elements to Indicate Sediment Provenance of Sand Ridges in Southwestern Yellow Sea显示文摘The Jianggang Harbour-centered radial sand ridge(RSR) is the largest sand body in the Yellow Sea. Its formation and evolution are of interest for scientists of various fields; however, the sediment provenance is uncertain. In this study, rare earth element(REE) geochemical compositions of the RSR sediments together with their potential sources are investigated to identify the provenance of the RSR sediments. The typical parameters((La/Yb)_N,(La/Sm)_N and(Gd/Yb)_N) as well as the upper continental crust-normalized patterns of REEs can only be associated with source rocks, and thus can be used as effective tracers for the origin and sources of sediments. However, the REE contents of sediments are affected by many factors, such as particle sorting and chemical weathering. Onshore RSR sediments are different in REE geochemical composition from offshore RSR sediments to some extent, suggesting that not all of the offshore RSR sediments have the same sources as the onshore RSR sediments. Meanwhile, the sediments adjacent to the northeast of Cheju Island and at Lian Island near the Lianyun Harbour were not the source of the RSR sediments due to their distinctive REE patterns, dEu,(La/Yb)_N,(Gd/Yb)_N and(La/Sm)_N. The Korean river sediments could be dispersed to the Jiangsu Coast slightly impacting the fine fractions of the RSR sediments, particularly the offshore RSR sediments. Additionally, geochemical comparisons show that the modern Yellow River was responsible for the onshore RSR sediments, whereas the sediment loads from the Yangtze River could serve as a major contributor to the RSR, particularly the offshore RSR. In addition, the offshore RSR could also be partly fed by an unknown source due to some high values of(La/Yb)_N,(La/Sm)_N and La contents differing from those of the Chinese and Korean river sediments. | LI Lei SU Jinbao RAO Wenbo WANG Yigang | 2017 | Chinese Geographical Science2017,27,1: | 4 |
| 14 | Cross-calibration of high energetic particles data——A case study between FY-3B and NOAA-17显示文摘Cross-calibration of high energetic particle data is a primary requirement for the availability of multi-instrument,multi-spacecraft data.It also can provide a method to verify relative reliability of data from single satellite measurement.This paper presents a case study of energetic particles data cross-calibration between FY-3B and NOAA-17.A generally good agreement is acquired in the flux values and distribution trend of 2.5–6.9 MeV protons and 0.3–1.1 MeV electrons between FY-3B and NOAA-17 satellites.It suggests that the data observed by FY-3B is properly cross-calibrated.We can also confirm that energetic particles data observed by FY-3B satellite is available. | WANG ChunQin ZHANG XianGuo LI JiaWei HUANG Cong ZHANG XiaoXin JING Tao SHEN GuoHong ZHANG ShenYi CAO GuangWei SUN YueQiang LIANG JinBao ZHU GuangWu HAN Ying | 2013 | Science China(Technological Sciences)2013,56,11: | 4 |
| 15 | The effects of wind-driven waves and ocean spray on the drag coefficient and near-surface wind profiles over the ocean显示文摘By introducing a wave-induced component and a spray-induced component to the total stress, a mathematical model based on the Ekman theory is proposed to detail the influence of wind-driven waves and ocean spray on the momentum transport in a marine atmosphere boundary layer(MABL). An analytic solution of the modified Ekman model can be obtained. The effect of the wave-induced stress is evaluated by a wind wave spectrum and a wave growth rate. It is found that the wave-induced stress and spray stress have a small impact compared with the turbulent stress on the drag coefficient and the wind profiles for low-to-medium wind speed. The spray contribution to the surface stress should be much more taken into account than the winddriven waves when the wind speed reaches above 25 m/s through the action of a 'spray stress'. As a result, the drag coefficient starts to decrease with increasing wind speed for high wind speed. The effects of the winddriven waves and spray droplets on the near-surface wind profiles are illustrated for different wave ages, which indicates that the production of the spray droplets leads the wind velocity to increase in the MABL. The solutions are also compared with the existed field observational data. Illustrative examples and the comparisons between field observations and the theoretical solutions demonstrate that the spray stress has more significant effect on the marine atmosphere boundary layer in the condition of the high wind speed compared with wave-induced stress. | ZHANG Ting SONG Jinbao LI Shuang YANG Liangui | 2016 | Acta Oceanologica Sinica2016,35,11: | 4 |
| 16 | Effect of minocycline on cerebral ischemia-reperfusion injury显示文摘Minocylcine, a tetracycline derivate, has been shown to cross the blood-brain barrier and enter the central nervous system. In this study, cerebral ischemia-reperfusion injury models were established using the suture method, and minocycline was immediately injected intraperitoneally after cerebral ischemia-reperfusion (22.5 mg/kg, initially 45 mg/kg) at a 12-hour interval. Results showed that after minocycline treatment, the volume of cerebral infarction was significantly reduced, the number of surviving cell in the hippocampal CA1 region increased, the number of apoptotic cells decreased, the expression of caspase-3 and poly(adenosine diphosphate-ribose) polymerase-1 protein was down-regulated, and the escape latency in the water maze test was significantly shortened compared with the ischemia-reperfusion group. Our experimental findings indicate that minocycline can protect against neuronal injury induced by focal ischemia-reperfusion, which may be mediated by the inhibition of caspase-3 and poly(adenosine diphosphate-ribose) polymerase-1 protein expression. | Yuanyin Zheng Lijuan Xu Jinbao Yin Zhichao Zhong Hongling Fan Xi Li Quanzhong Chang | 2013 | Neural Regeneration Research2013,8,10: | 4 |

| 18 | On weakly S-embedded subgroups of finite groups显示文摘Let H be a subgroup of a group G.Then H is said to be S-quasinormal in G if HP = P H for every Sylow subgroup P of G;H is said to be S-quasinormally embedded in G if a Sylow p-subgroup of H is also a Sylow p-subgroup of some S-quasinormal subgroup of G for each prime p dividing the order of H.In this paper,we say that H is weakly S-embedded in G if G has a normal subgroup T such that HT is an S-quasinormal subgroup of G and H ∩ T≤H SE,where H SE denotes the subgroup of H generated by all those subgroups of H which are S-quasinormally embedded in G.Some results about the influence of weakly S-embedded subgroups on the structure of finite groups are given. | LI JinBao CHEN GuiYun CHEN RuiFang | 2011 | Science China Mathematics2011,54,9: | 3 |

| 20 | A molecular cobaloxime cocatalyst and ultrathin FeOOH nanolayers co-modifiedBiVO_(4) photoanode for efficient photoelectrochemical water oxidation显示文摘BiVO_(4) has been attracting a lot of interest in photoelectrochemical (PEC) water oxidation due to its efficient solar absorption and appropriate band positions.So far,sluggish water oxidation kinetics and fast photogenerated charge recombination still hinder the PEC performance ofBiVO_(4) .In this study,a novel PEC photoanode was designed by depositing ultrathin FeOOH nanolayers on the surface of nanoporousBiVO_(4) electrode,followed by modification with a cobaloxime (Co(dmgH)_(2)(4-COOH-py)Cl) molecular cocatalyst.Under irradiation of a 100 mW cm^(-2)(AM 1.5G) Xe lamp,the photocurrent density of the cobaloxime/FeOOH/BiVO_(4) composite photoanode reached 5.1 mA cm^(-2)at 1.23 V vs.RHE in 1.0 M potassium borate buffer solution (pH=9.0).The onset potential of the optimal cobaloxime/FeOOH/BiVO_(4) photoanode exhibited a 460 m V cathodic shift relative to bareBiVO_(4) .In addition,the surface charge injection efficiency of the composite photoanode reached~80%at 1.23 V vs.RHE and the incident photon-to-current efficiency (IPCE) reached~88%at 420 nm. | Hongyun Cao Taotao Wang Jiaxing Li Jinbao Wu Pingwu Du | 2022 | Journal of Energy Chemistry2022,31,6: | 3 |
