| 1 | Strata movement controlling effect of waste and fly ash backfillings in fully mechanized coal mining with backfilling face显示文摘A fully mechanized coal mining with backfilling (FMCMB) provides advantages of safety and efficiency for coal mining under buildings, railways, and water bodies. According to the field geological conditions, we analyzed the controlling effect of strata movement by the waste and fly ash backfilling in FMCMB face. Based on the key strata theory, we established the equivalent mining thickness model, and analyzed the action of the bulk factor of backfilling body to the equivalent mining thickness. In addition, we numerically simulated the controlling function of the strata movement by backfilling bodies with differ- ent strength. And the numerical simulation result show that the deformation of stratum and the subsi- dence of surface can be controlled by FMCMB. The result provides references to the effective execution of fully mechanized coal mining with solid waste backfilling in goaf. | Zhang Jixiong Zhang Qiang Huang Yanli Liu Jinwei Zhou Nan Zan Dongfeng | 2011 | Mining Science and Technology2011，21，5： | 27 |
| 2 | Perspectives on studies on soil carbon stocks and the carbon sequestration potential of China显示文摘Soil carbon stocks and sequestration have been given a lot of attention recently in the study of terrestrial ecosystems and global climate change.This review focuses on the progress made on the estimation of the soil carbon stocks of China,and the characterization of carbon dynamics of croplands with regard to climate change,and addresses issues on the mineralization of soil organic carbon in relation to greenhouse gas emissions.By integrating existing research data,China's total soil organic carbon(SOC) stock is estimated to be 90 Pg and its inorganic carbon(SIC) stock as 60 Pg,with SOC sequestration rates in the range of 20-25 Tg/a for the last two decades.An estimation of the biophysical potential of SOC sequestration has been generally agreed as being 2 Pg over the long term,of which only 1/3 could be attainable using contemporary agricultural technologies in all of China's croplands.Thus,it is critical to enhance SOC sequestration and mitigate climate change to improve agricultural and land use management in China.There have been many instances where SOC accumulation may not induce an increased amount of decomposition under a warming scenario but instead favor improved cropland productivity and ecosystem functioning.Furthermore,unchanged or even decreased net global warming potential(GWP) from croplands with enhanced SOC has been reported by a number of case studies using life cycle analysis.Future studies on soil carbon stocks and the sequestration potential of China are expected to focus on:(1) Carbon stocks and the sequestration capacity of the earths' surface systems at scales ranging from the plot to the watershed and(2) multiple interface processes and the synergies between carbon sequestration and ecosystem productivity and ecosystem functioning at scales from the molecular level to agro-ecosystems.Soil carbon science in China faces new challenges and opportunities to undertake integrated research applicable to many areas. | ZHENG JuFeng CHENG Kun PAN GenXing Pete SMITH LI LianQing ZHANG XuHui ZHENG JinWei HAN XiaoJun DU YanLing | 2011 | Chinese Science Bulletin2011，56，35： | 24 |
| 3 | Cropland redistribution to marginal lands undermines environmental sustainability显示文摘Cropland redistribution to marginal land has been reported worldwide;however,the resulting impacts on environmental sustainability have not been investigated sufficiently.Here we investigated the environmental impacts of cropland redistribution in China.As a result of urbanization-induced loss of high-quality croplands in south China(~8.5 t ha^(-1)),croplands expanded to marginal lands in northeast(~4.5 t ha^(-1)) and northwest China(~2.9 t ha^(-1)) during 1990-2015 to pursue food security.However,the reclamation in these low-yield and ecologically vulnerable zones considerably undermined local environmental sustainability,for example increasing wind erosion(+3.47%),irrigation water consumption(+34.42%),fertilizer use(+20.02%) and decreasing natural habitats(-3.11%).Forecasts show that further reclamation in marginal lands per current policies would exacerbate environmental costs by 2050.The future cropland security risk will be remarkably intensified because of the conflict between food production and environmental sustainability.Our research suggests that globally emerging reclamation of marginal lands should be restricted and crop yield boost should be encouraged for both food security and environmental benefits. | Wenhui Kuang Jiyuan Liu Hanqin Tian Hao Shi Jinwei Dong Changqing Song Xiaoyong Li Guoming Du Yali Hou Dengsheng Lu Wenfeng Chi Tao Pan Shuwen Zhang Rafiq Hamdi Zherui Yin Huimin Yan Changzhen Yan Shixin Wu Rendong Li Jiuchun Yang Yinyin Dou Wenbin Wu Liqiao Liang Bao Xiang Shiqi Yang | 2022 | National Science Review2022，9，1： | 13 |
| 4 | Study on stabilities and electrochemical behavior of V(V) electrolyte with acid additives for vanadium redox flow battery显示文摘Several acid compounds have been employed as additives of the V(V) electrolyte for vanadium redox flow battery(VRB) to improve its stability and electrochemical activity. Stability of the V(V) electrolyte with and without additives was investigated with ex-situ heating/cooling treatment at a wide temperature range of-5 ?C to 60 ?C. It was observed that methanesulfonic acid, boric acid, hydrochloric acid, trifluoroacetic acid,polyacrylic acid, oxalic acid, methacrylic acid and phosphotungstic acid could improve the stability of the V(V) electrolyte at a certain range of temperature. Their electrochemical behaviors in the V(V) electrolyte were further studied by cyclic voltammetry(CV), steady state polarization and electrochemical impedance spectroscopy(EIS). The results showed that the electrochemical activity, including the reversibility of electrode reaction, the diffusivity of V(V) species, the polarization resistance and the flexibility of charge transfer for the V(V) electrolyte with these additives were all improved compared with the pristine solution. | Gang Wang Jinwei Chen Xueqin Wang Jing Tian Hong Kang Xuejing Zhu Yu Zhang Xiaojiang Liu Ruilin Wang | 2014 | Journal of Energy Chemistry2014，23，1： | 10 |
| 5 | Petrogenetic differences between the Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range,South China: A case study of the Tongshanling and Weijia deposits in southern Hunan Province显示文摘The Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range have distinctly different mineralogical and geochemical signatures. The Cu-Pb-Zn-bearing granites are dominated by metaluminous amphibole-bearing granodiorites, which have higher CaO/(Na2O+K2O) ratios, light/heavy rare earth element(LREE/HREE) ratios, and δEu values,lower Rb/Sr ratios, and weak Ba, Sr, P, and Ti depletions, exhibiting low degrees of fractionation. The W-bearing granites are highly differentiated and peraluminous, and they have lower CaO/(Na2O+K2O) ratios, LREE/HREE ratios, and δEu values,higher Rb/Sr ratios, and strong Ba, Sr, P, and Ti depletions. The Cu-Pb-Zn-bearing granites were formed predominantly between155.2 and 167.0 Ma with a peak value of 160.6 Ma, whereas the W-bearing granites were formed mainly from 151.1 to 161.8Ma with a peak value of 155.5 Ma. There is a time gap of about 5 Ma between the two different types of ore-bearing granites.Based on detailed geochronological and geochemical studies of both the Tongshanling Cu-Pb-Zn-bearing and Weijia W-bearing granites in southern Hunan Province and combined with the other Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range, a genetic model of the two different types of ore-bearing granites has been proposed. Asthenosphere upwelling and basaltic magma underplating were induced by the subduction of the palaeo-Pacific plate. The underplated basaltic magmas provided heat to cause a partial melting of the mafic amphibolitic basement in the lower crust, resulting in the formation of Cu-Pb-Zn mineralization related granodioritic magmas. With the development of basaltic magma underplating,the muscovite-rich metasedimentary basement in the upper-middle crust was partially melted to generate W-bearing granitic magmas. The compositional difference of granite sources accounted for the metallogenic specialization, and the non-simultaneous partial melting of one source followed by the other brought about a time gap of about 5 Ma between the Cu-Pb-Zn-bearing and W-bearing granites. | HUANG XuDong LU JianJun Stanislas SIZARET WANG RuCheng MA DongSheng ZHANG RongQing ZHAO Xu WU JinWei | 2017 | Science China Earth Sciences2017，60，7： | 9 |
| 6 | Fingered Intrusion of Shallow Saucer-shaped Igneous Sills: Insights from the Jiaojiang Sag, East China Sea显示文摘An extensive suite of igneous sills was intruded into the Tertiary sedimentary section of the Jiaojiang sag,East China Sea.This suite has been well imaged offshore through 2D and 3D seismic surveys,showing a close relationship with CO2 content in nearby gas discoveries.A new observational model,which incorporates simple upward propagation,simple horizontal propagation,and transgressive propagation,was proposed to interpret these sill intrusions.In this model,the source magma of the saucer-shaped sills was injected from their lowest points near the center.The transgressive propagation can be interpreted as a combination of the vertical and horizontal propagation.Most shallow sub-volcanic intrusions in the Jiaojiang sag exhibit fingered characteristics,both vertically and horizontally.The vertical fingered propagation produced saucer-shaped sills arranged in the flower style.Along the brims of lower sills could usually be found the upper sills,which are interpreted to have formed simultaneously with or later than the lower feeder sills.In the second type,the chilled paths of the older sills were reutilized by subsequent intrusions.The horizontal fingered propagation formed sheet intrusions that exhibit groove,lobate,tubular,and crevasse splaylike geometry in plan view.In 3D view,the sheet intrusions have still preserved the lower center and higher rim that similar with the sub-rounded saucer-shaped sills.Although fracture propagation may be important,flow inflation was the key mechanism of magma intrusion.Further consideration of the mechanisms underlying sill formation may help explain the fingered characteristics of sill propagation. | GUO Rui ZHANG Gongcheng ZHANG Jinwei ZHAO Xingbin LIU Junbang YUAN Dawei SONG Shuang | 2013 | Acta Geologica Sinica(English Edition)2013，87，5： | 8 |
| 7 | The Late Pleistocene activity of the eastern part of east Kunlun fault zone and its tectonic significance显示文摘The nearly EW-trending East Kunlun fault zone is the north boundary of the Bayan Har block.The activity characteristics and the position of the eastern end of its eastward extension are of great significance to probing into the dynamic mechanism of formation of the east edge of the Tibetan Plateau,and also lay the foundation for seismic risk assessment of the fault zone.The following results are obtained by analysis based on satellite image interpretation of landforms,surface rupture survey,terrace scarp deformation survey,and terrace dating data on the eastern part of the East Kunlun fault zone:(1)the Luocha segment is a Holocene active fault,where a reverse L-shape paleoearthquake surface rupture zone of about 50 km long is located;(2)the Luocha segment is characterized by left-lateral slip movement under the compression-shear condition since the later period of the Late Pleistocene,with a rate of 7.68–9.37 mm/a and a vertical slip rate of 0.7–0.9 mm/a,which are basically in accord with the activity rate of segments on its west side.The results indicate that it is a part of eastward extension of the East Kunlun fault zone;(3)the high-speed linear horizontal slip of the nearly EW-trending East Kunlun fault zone is blocked by the South China block at east,and transforms into the vertical movement of the nearly SN-NNE trending Minjiang fault zone and the Longmenshan fault zone,and the uplift of Longmenshan and Minjiang.The area where transform of the two tectonic systems occurred confines the position of the east end;(4)Luocha segment and Maqu segment constitute the'Maqu seismic gap',so,seismic risk at Maqu segment is higher than that at Luocha segment,which should attract more attention. | ZHANG JunLong REN JinWei CHEN ChangYun FU JunDong YANG PanXin XIONG RenWei HU ChaoZhong | 2014 | Science China Earth Sciences2014，57，3： | 8 |
| 8 | Recent developments in electrocatalysts and future prospects for oxygen reduction reaction in polymer electrolyte membrane fuel cells显示文摘The main difficulty in the extensive commercial use of polymer electrolyte membrane fuel cells(PEMFCs)is the use of noble metals such as Pt-based electrocatalyst at the cathode, which is essential to ease the oxygen reduction reaction(ORR) in fuel cells(FCs). To eliminate the high loading of Pt-based electrocatalysts to minimize the cost, extensive study has been carried out over the previous decades on the non-noble metal catalysts. Development in enhancing the ORR performance of FCs is mainly due to the doped carbon materials, Fe and Co-based electrocatalysts, these materials could be considered as probable substitutes for Pt-based catalysts. But the stability of these non-noble metal electrocatalysts is low and the durability of these metals remains unclear. The three basic reasons of instability are:(i) oxidative occurrence by H_2O_2,(ii) leakage of the metal site and(iii) protonation by probable anion adsorption of the active site. Whereas leakage of the metal site has been almost solved, more work is required to understand and avoid losses from oxidative attack and protonation. The ORR performance such as stability tests are usually run at low current densities and the lifetime is much shorter than desired need. Therefore,improvement in the ORR activity and stability are the key issues of the non-noble metal electrocatalyst.Based on the consequences obtained in this area, numerous future research directions are projected and discussed in this paper. Hence, this review is focused on improvement of stability and durability of the non-noble metal electrocatalyst. | Maryam Kiani Jie Zhang Yan Luo Chunping Jiang Jinlong Fan Gang Wang Jinwei Chen Ruilin Wang | 2018 | Journal of Energy Chemistry2018，27，4： | 7 |
| 9 | Prevalence and treatment of hypertension in China: impacts of 2017 American College of Cardiology/American Heart Association High Blood Pressure Guideline显示文摘The definition, recommended treatment thresholds and targets of hypertension have been updated in the recent 2017 American College of Cardiology/American Heart Association(ACC/AHA) Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults. However,the impacts of this guideline on Chinese population are currently unknown. In this study, we aim to provide updated data in China using criteria from the updated guideline. A multistage, stratified sampling method was used to obtain a representative sample of 50,171 adults aged 18 years and above.Hypertension was defined as an average systolic blood pressure !130 mm Hg, or an average diastolic blood pressure !80 mm Hg, or self-reported use of antihypertensive medications in past 2 weeks. The weighted prevalence of hypertension was 60.1%(95% confidence interval [CI] 59.3%–61.0%). The treatment rate and recommended treatment rate were 16.8%(95% CI 16.1%–17.6%) and 53.7%(95% CI52.6%–54.9%), respectively; the gap was more prominent among men and participants from rural areas.Hence, the adoption of the 2017 ACC/AHA guideline will lead to a substantial increase in both prevalence and number of patients needing treatment in China. The applicability of this guideline should be carefully evaluated based on evidence from Chinese population. | Chao Yang Jinwei Wang Bixia Gao Yan Zhang Fang Wang Luxia Zhang Minghui Zhao Yong Huo | 2018 | Science Bulletin2018，63，8： | 7 |
| 10 | Regulatory control of the Na-Cl co-transporter NCC and its therapeutic potential for hypertension显示文摘Hypertension is the largest risk factor for cardiovascular disease,the leading cause of mortality worldwide.As blood pressure regulation is influenced by multiple physiological systems,hypertension cannot be attributed to a single identifiable etiology.Three decades of research into Mendelian forms of hypertension implicated alterations in the renal tubular sodium handling,particularly the distal convoluted tubule(DCT)-native,thiazide-sensitive Na-Cl cotransporter(NCC).Altered functions of the NCC have shown to have profound effects on blood pressure regulation as illustrated by the over activation and inactivation of the NCC in Gordon’s and Gitelman syndromes respectively.Substantial progress has uncovered multiple factors that affect the expression and activity of the NCC.In particular,NCC activity is controlled by phosphorylation/dephosphorylation,and NCC expression is facilitated by glycosylation and negatively regulated by ubiquitination.Studies have even found parvalbumin to be an unexpected regulator of the NCC.In recent years,there have been considerable advances in our understanding of NCC control mechanisms,particularly via the pathway containing the with-no-lysine[K](WNK)and its downstream target kinases,SPS/Ste20-related proline-alanine-rich kinase(SPAK)and oxidative stress responsive 1(OSR1),which has led to the discovery of novel inhibitory molecules.This review summarizes the currently reported regulatory mechanisms of the NCC and discusses their potential as therapeutic targets for treating hypertension. | Nur Farah Meor Azlan Maarten P.Koeners Jinwei Zhang | 2021 | Acta Pharmaceutica Sinica B2021，11，5： | 6 |

| 13 | Precise determination of the reference point coordinates of Shanghai Tianma 65-m radio telescope显示文摘A local survey was implemented at the newly constructed Shanghai Tianma 65-m radio telescope.In this article,the survey implementation and data analysis are described.Particularly,by application of coordinate transformation,dimensionality reduction and step fitting of parameters,as well as adoption of reliability test measures of parameters,the mathematical model of data analysis is simplified,the detrimental effects of observation noises and unevenly spatial coverage of sample points are effectively compressed,the stability and precision of parameter solutions are improved,and so the geocentric three-dimensional coordinates of the reference point of this telescope in the precision of millimeters were determined,and the axisoffset was shown not significant on the precision level of3 mm.The outcome provides important reference to the subsequent activities of antenna maintenance and scientific application,including the establishment of precise antenna orientation model,orientation guidance,fringe searching in data cross-correlation,analysis and application studies of VLBI observations.It is also important archive data for monitoring possible subsidence and lateral displacement of antenna foundation as well as deformation of antenna tracking-rail and structure. | Jinling Li Fuwen Xiong Chenglei Yu Jinwei Zhang Li Guo Qingyuan Fan | 2014 | Chinese Science Bulletin2014，59，21： | 5 |
| 14 | Thermal Influence of the Couette Flow in a Hydrostatic Spindle on the Machining Precision显示文摘Hydrostatic spindles are increasingly used in precision machine tools. Thermal error is the key factor affecting the machining accuracy of the spindle, and research has focused on spindle thermal errors through examination of the influence of the temperature distribution, thermal deformation and spindle mode. However, seldom has any research investigated the thermal effects of the associated Couette flow. To study the heat transfer mechanism in spindle systems, the criterion of the heat transfer direction according to the temperature distribution of the Couette flow at different temperatures is deduced. The method is able to deal accurately with the significant phenomena occurring at every place where thermal energy flowed in such a spindle system. The variation of the motion error induced by thermal effects on a machine work-table during machining is predicated by establishing the thermo-mechanical error model of the hydrostatic spindle for a high precision machine tool. The flow state and thermal behavior of a hydrostatic spindle is analyzed with the evaluated heat power and the coefficients of the convective heat transfer over outer surface of the spindle are calculated, and the thermal influence on the oil film stiffness is evaluated. Thermal drift of the spindle nose is measured with an inductance micrometer, the thermal deformation data 1.35 μm after running for 4 h is consistent with the value predicted by the finite element analysis's simulated result 1.28 μm, and this demonstrates that the simulation method is feasible. The thermal effects on the processing accuracy from the flow characteristics of the fluid inside the spindle are analyzed for the first time. | CHEN Dongju FAN Jinwei LI Haiyong WANG Xiaofeng ZHANG Feihu | 2013 | Chinese Journal of Mechanical Engineering2013，26，3： | 5 |
| 15 | SO_2/Hg removal from flue gas by dry FGD显示文摘To study the mechanism of SO 2 and Hg removal from flue gas, an experimental packed bed reactor was designed to simulate the dry FGD, where a mixture of lime and fly ash in ratio 1:3 w/w was used as the SO 2 and Hg sorbent, and steam at temperature of 100℃ was applied for activation of the sorbent, while the activation time set to 20 min. The experimental factors including the SO 2 /Hg sorbent characteristics, 50% breakthrough time for SO 2 /Hg removal, sorbent packed bed depth and reaction temperature were investigated. The experimental results show that after steam activation, the BET specific surface area and specific pore volume increased from 37.8 to 45.5 m 2 /g and from 0.42 to 0.51 cm 3 /g, respectively. With activation of the sorbent by steam, the 50% breakthrough times of SO 2 and Hg removal increased from 34 to 42 min and from 23 to 45 min, respectively. When the packed bed depth was increased from 5 to 25 mm, the 50% breakthrough times for Hg and SO 2 removal increased from 12 to 52 min and from 6 to 47 min, respectively. With the increase of the reaction temperature, the 50% breakthrough of SO 2/Hg removal decreased accordingly. Steam activation can efficiently improve SO 2 /Hg removal simultaneously. | Wang Fan Wang Hongmei Zhang Fan Zhu Jinwei Tian Gang Liu Yu Mao Jixian | 2012 | International Journal of Mining Science and Technology2012，22，1： | 5 |
| 16 | Treatment of malignant glioma using hyperthermia显示文摘Thirty pathologically diagnosed patients with grade III–IV primary or recurrent malignant glioma(tumor diameter 3–7 cm)were randomly divided into two groups.The control group underwent conventional radiotherapy and chemotherapy.In the hyperthermia group,primary cases received hyperthermia treatment,and patients with recurrent tumors were treated with hyperthermia in combination with radiotherapy and chemotherapy.Hyperthermia treatment was administered using a13.56-MHz radio frequency hyperthermia device.Electrodes were inserted into the tumor with the aid of a CT-guided stereotactic apparatus and heat was applied for 1 hour.During 3 months after hyperthermia,patients were evaluated with head CT or MRI every month.Gliomas in the hyperthermia group exhibited growth retardation or growth termination.Necrosis was evident in 80%of the heated tumor tissue and there was a decrease in tumor diameter.Our findings indicate that radio frequency hyperthermia has a beneficial effect in the treatment of malignant glioma. | Jiahang Sun Mian Guo Hengyuan Pang Jingtao Qi Jinwei Zhang Yunlong Ge | 2013 | Neural Regeneration Research2013，8，29： | 5 |

| 18 | Comparison of three remotely sensed drought indices for assessing the impact of drought on winter wheat yield显示文摘Agricultural drought threatens food security.Numerous remote-sensing drought indices have been developed,but their different principles,assumptions and physical quantities make it necessary to compare their suitability for drought monitoring over large areas.Here,we analyzed the performance of three typical remote sensing-based drought indices for monitoring agricultural drought in two major agricultural production regions in Shaanxi and Henan provinces,northern China(predominantly rain-fed and irrigated agriculture,respectively):vegetation health index(VHI),temperature vegetation dryness index(TVDI)and drought severity index(DSI).We compared the agreement between these indices and the standardized precipitation index(SPI),soil moisture,winter wheat yield and National Meteorological Drought Monitoring(NMDM)maps.On average,DSI outperformed the other indices,with stronger correlations with SPI and soil moisture.DSI also corresponded better with soil moisture and NMDM maps.The jointing and grain-filling stages of winter wheat are more sensitive to water stress,indicating that winter wheat required more water during these stages.Moreover,the correlations between the drought indices and SPI,soil moisture,and winter wheat yield were generally stronger in Shaanxi province than in Henan province,suggesting that remote-sensing drought indices provide more accurate predictions of the impacts of drought in predominantly rain-fed agricultural areas. | Jianxi Huang Wen Zhuo Ying Li Ran Huang Fernando Sedano Wei Su Jinwei Dong Liyan Tian Yanbo Huang Dehai Zhu Xiaodong Zhang | 2020 | International Journal of Digital Earth2020，13，4： | 4 |
