2Effects of vegetation height and density on soil temperature variations显示文摘Reduction in vegetation cover caused by human activities has a great impact on soil temperature. It is important to assess how soil temperature responds to reduction of vegetation height and density. In this paper we first report the trends of mean annual soil surface and air temperatures recorded at the meteorological stations near the Ecological Research Station for Grassland Farming (ERSGF) from 1961 to 2007, then we setup an experiment using reed (Phragmites australis) stalks with different heights and densities to simulate effects of different vegetation height and density on soil and air temperatures. The warming rates of the mean annual soil and air temperatures were 0.043 and 0.041C a 1 , respectively. Changes of soil temperature were characterized by both increased mean annual maximum and minimum soil temperatures. At the experimental site, mean daily temperature, mean daily maximum soil and air temperatures increased significantly. In contrast, mean daily minimum soil temperature increased significantly while mean daily minimum air temperature decreased significantly as the height and density of reed stalks reduced during the experimental period. Mean diurnal soil temperature ranges were smaller than mean diurnal air temperature ranges. These results highlight that the importance of vegetation cover on soil and air temperatures.SONG YanTao ZHOU DaoWei ZHANG HongXiang LI GuangDi JIN YingHua LI Qiang 2013Chinese Science Bulletin2013,58,8:12
3Carbon pools and fluxes in the China Seas and adjacent oceans显示文摘The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange at the sea-air interface is considered, the Chinese marginal seas appear to be a source of atmospheric CO_2, with a net release of 6.01–9.33 Tg C yr^(-1), mainly from the inputs of rivers and adjacent oceans. The riverine dissolved inorganic carbon (DIC) input into the Bohai Sea and Yellow Sea, East China Sea, and South China Sea are 5.04, 14.60, and 40.14 Tg C yr^(-1),respectively. The DIC input from adjacent oceans is as high as 144.81 Tg C yr^(-1), significantly exceeding the carbon released from the seas to the atmosphere. In terms of output, the depositional fluxes of organic carbon in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea are 2.00, 3.60, 7.40, and 5.92 Tg C yr^(-1), respectively. The fluxes of organic carbon from the East China Sea and South China Sea to the adjacent oceans are 15.25–36.70 and 43.93 Tg C yr^(-1), respectively. The annual carbon storage of mangroves, wetlands, and seagrass in Chinese coastal waters is 0.36–1.75 Tg C yr^(-1), with a dissolved organic carbon(DOC) output from seagrass beds of up to 0.59 Tg C yr^(-1). Removable organic carbon flux by Chinese macroalgae mariculture account for 0.68 Tg C yr^(-1) and the associated POC depositional and DOC releasing fluxes are 0.14 and 0.82 Tg C yr^(-1), respectively. Thus, in total, the annual output of organic carbon, which is mainly DOC, in the China Seas is 81.72–104.56 Tg C yr^(-1). The DOC efflux from the East China Sea to the adjacent oceans is 15.00–35.00 Tg C yr^(-1). The DOC efflux from the South China Sea is 31.39 Tg C yr^(-1). Although the marginal China Seas seem to be a source of atmospheric CO_2 based on the CO_2 flux at the sea-air interface, the combined effects of the riverine input in the area, oceanic input, depositional export,and microbial carbon pump(DOC conversion and output) indicate that the China Seas represent an important carbon storage area.Nianzhi JIAO Yantao LIANG Yongyu ZHANG Jihua LIU Yao ZHANG Rui ZHANG Meixun ZHAO Minhan DAI Weidong ZHAI Kunshan GAO Jinming SONG Dongliang YUAN Chao LI Guanghui LIN Xiaoping HUANG Hongqiang YAN Limin HU Zenghu ZHANG Long WANG Chunjie CAO Yawei LUO Tingwei LUO Nannan WANG Hongyue DANG Dongxiao WANG Si ZHANG 2018Science China Earth Sciences2018,61,11:12
4Effects of fencing on vegetation and soil restoration in a degraded alkaline grassland in northeast China显示文摘In order to restore a degraded alkaline grassland, the local government implemented a large restoration project using fences in Changling county, Jilin province, China, in 2000. Grazing was excluded from the protected area, whereas the grazed area was continuously grazed at 8.5 dry sheep equivalent(DSE)/hm2. In the current research, soil and plant samples were taken from grazed and fenced areas to examine changes in vegetation and soil properties in 2005, 2006 and 2008. Results showed that vegetation characteristics and soil properties improved significantly in the fenced area compared with the grazed area. In the protected area the vegetation cover, height and above- and belowground biomass increased significantly. Soil pH, electrical conductivity and bulk density decreased significantly, but soil organic carbon and total nitrogen concentration increased greatly in the protected area. By comparing the vegetation and soil characteristics with pre-degraded grassland, we found that vegetation can recover 6 years after fencing, and soil pH can be restored 8 years after fencing. However, the restoration of soil organic carbon, total nitrogen and total phosphorus concentrations needed 16, 30 and 19 years, respectively. It is recommended that the stocking rate should be reduced to 1/3 of the current carrying capacity, or that a grazing regime of 1-year of grazing followed by a 2-year rest is adopted to sustain the current status of vegetation and soil resources. However, if N fertilizer is applied, the rest period could be shortened, depending on the rate of application.Qiang LI DaoWei ZHOU YingHua JIN MinLing WANG YanTao SONG GuangDi LI 2014Journal of Arid Land2014,6,4:9
5Purification and Characterization of a New Ribosome Inactivating Protein from Cinchonaglycoside C-treated Tobacco Leaves显示文摘A new ribosome-inactivating protein(RIP)with a molecular weight of 31 kDa induced by Cinchonaglycoside C(1)designatedCLP31,was isolated from tobacco leaves.Analysis of this protein sequence indicated that it belongs to the RIP family and itwas distinct from the other plant RIPs reported previously at its N-terminal amino acid sequence.CIP31 can directly impairsynthesis of coat protein(CP)of tobacco mosaic virus(TMV),which resulted in inhibition of TMV long distance movementand multiplication in tobacco plants at concentrations of ng/mL.Furthermore,no toxicity was shown to the growth andfertility of the plants.CIP31 was synthesized only in the presence of Cinchonaglycoside C(1)and was independent of thesalicylic acid(SA)signal pathway.We provided evidence for the SA-independent biological induction of resistance.Yanmei Li Yantao Jia Zhongkai Zhang Xiaoying Chen Hongping He Rongxiang Fang Xiaojiang Hao 2007Journal of Integrative Plant Biology2007,49,9:8
6Polyaspartic acid as a corrosion inhibitor for WE43 magnesium alloy显示文摘The inhibition behavior of polyaspartic acid(PASP)as an environment-friendly corrosion inhibitor for WE43 magnesium alloy was investigated in 3.5 wt.%NaCl solution by means for EIS measurement,potentiodynamic polarization curve,and scanning electron microscopy.The results show that PASP can inhibit the corrosion of WE43 magnesium alloy.The maximum inhibition efficiency is achieved when PASP concentration is 400 ppm in this study.Lihui Yang Yantao Li Bei Qian Baorong Hou 2015Journal of Magnesium and Alloys2015,3,1:8

8Carbon sequestration processes and mechanisms in coastal mariculture environments in China显示文摘China is the global leader in mariculture production. Increasing sequestered marine carbon(also known as blue carbon) via mariculture activities is a promising approach for mitigating climate change and promoting the development of a low-carbon economy. Mariculture blue carbon is also considered an important component of China's 'sea granary'. In addition to shellfish and macroalgae yields, which represent carbon removed from mariculture environment, blue carbon also includes other important components, which have been largely neglected in the past, such as the carbon transformed by microbes,dissolved organic carbon(mainly referred to as recalcitrant dissolved organic carbon), and sedimentary particulate carbon. Hence,from different aspects, a comprehensive study on the formation processes and mechanisms of carbon sequestration is of great significance for comprehensively unveiling the carbon sequestration capability in coastal mariculture environment, which will contribute to the sustainable development of the fishery economy and construction of an ecological civilization. Moreover, it may add significant economic benefits to the future carbon-trading market.ZHANG YongYu ZHANG JiHong LIANG YanTao LI HongMei LI Gang CHEN Xiao ZHAO Peng JIANG ZengJie ZOU DingHui LIU XiaoYong LIU JiHua 2017Science China Earth Sciences2017,60,12:7

10Power allocation for OFDM-based cognitive heterogeneous networks显示文摘In this paper,the capacity maximization and the spectrum utilization efficiency improvement are investigated for the Pico cells in broadband heterogeneous networks.In frequency-reuse model,the users attached to Macro base station are usually viewed as primary users,and those attached to Pico base station should be regarded as cognitive radio(CR) users.As both the primary users and the CR users communicate in parallel frequency bands,the performance of the system is limited by the mutual inter-carrier interference(ICI).In order to control ICI and maximize the achievable transmission rate of the CR users,an effective power allocation scheme is proposed to maximize the transmission rate of the CR users under a given interference threshold prescribed by the primary users.By transforming this suboptimal solution into an innovative matrix expression,the algorithm is easier to perform in practice.The simulation results demonstrate that the proposed algorithm provides a large performance gain in Pico cell capacity over the non-cooperative and equal power allocation schemes.FEI ZeSong XING ChengWen LI Na HAN YanTao DANEV Danyo KUANG JingMing 2013Science China(Information Sciences)2013,56,4:5
11Statistically robust resource allocation for distributed multi-carrier cooperative networks显示文摘In this paper, we investigate joint subcarrier and power allocation scheme for distributed multicarrier cooperative networks with imperfect channel state information. Using practical channel estimation algorithms, the statistic model of the channel estimation error is first derived. Then based on the channel error model, the resource allocation scheme aims at maximizing the sum rate of the overall network. Specifically, both subcarrier allocation and power allocation are taken into account. In the subcarrier allocation, a realistic problem of the power leakage between neighboring subcarriers is also addressed. Furthermore, based on Lagrange dual-decomposition algorithm, a practical power allocation algorithm is proposed. Finally, the simulation results demonstrate the performance advantages of the proposed robust design.XING ChengWen FEI ZeSong LI Na HAN YanTao DANEV Danyo KUANG JingMing 2013Science China(Information Sciences)2013,56,2:5
12Prevalence of liver injury among patients with acquired immunodeficiency syndrome treated with highly active antiretroviral therapy in China显示文摘OBJECTIVE: To estimate the prevalence of liver injury among patients with acquired immunodeficiency syndrome(AIDS) who received highly active antiretroviral therapy(HAART) in rural Henan Province in China, and to explore whether Traditional Chinese Medicine(TCM) treatment based on HAART would increase this risk.METHODS: This was a retrospective cross-sectional study. We collected medical information on patients with AIDS from two treatment databases in2014. Criteria established by the AIDS Clinical Trials Group in 1996 were used for grading liver injury,classified based on the limit of normal(ULN) for alanine transaminase and aspartate aminotransferase:grade 1(1.25-2.5 × ULN); grade 2(2.6-5 × ULN);grade 3(5.1-10 × ULN); and grade 4(> 10 × ULN).Factors associated with liver injury were evaluated using a logistic regression model.RESULTS: A total 6953 patients with AIDS(3324 male and 3629 female patients) were enrolled into this study. The prevalence of liver injury was 22.0%(18.0% grade 1, 3.1% grade 2, 0.9% grade 3). In multivariate analysis, patients aged 34-45 years were more likely to have liver injury than patients in other age groups [adjusted odds ratio(AOR), 1.39; 95%CI, 1.01-1.91)]. Other factors associated with liver injury included male sex(AOR, 1.64; 95% CI,1.46-1.85), HIV infection via blood(AOR, 1.47; 95%CI, 1.19-1.82), hepatitis B virus antibody positive(AOR, 1.07; 95% CI, 0.85-1.36), and hepatitis C virus(HCV) antibody positive(AOR, 2.76; 95% CI,2.28-3.34).CONCLUSION: The prevalence of liver injury was relatively high among HAART-experienced patients. Several factors associated with liver injury included male sex, age 35-45 years old, HIV infection through blood, and concurrent HCV infection. TCM had no relationship with liver injury in patients receiving HAART.Yuan Jun Xu Qianlei Chen Xiumin Meng Pengfei Li Qingya Xu Liran Meng Xiangle Jin Yantao Guo Huijun 2019Journal of Traditional Chinese Medicine2019,39,2:5
13Anisotropy of the crystallographic orientation and corrosion performance of high-strength AZ80 Mg alloy显示文摘A high-strength AZ80 Mg alloy was prepared through multi-direction forging,thermal extrusion,and peak-aged heat treatment.The microstructure,crystallographic orientation and corrosion performance of extrusion-direction,transverse-direction,and normal-direction specimens were investigated using scanning electron microscopy,electron backscatter diffraction,and atomic force microscopy,respectively.Experimental results showed that crystallographic orientation significantly influenced the corrosion performance of AZ80 Mg alloy.Corrosion rates largely increased with decreased(0001)crystallographic plane intensity,whereas the(10−10)and(2−1−10)crystallographic plane intensities increased.This study showed that the corrosion rates of alloy can be modified to some extent by controlling texture,thereby promoting the applications of high-strength AZ80 Mg alloys in the aerospace and national-defense fields.Quantong Jiang Xiumin Ma Kui Zhang Yantao Li Xinggang Li Yongjun Li Minglong Ma Baorong Hou 2015Journal of Magnesium and Alloys2015,3,4:5

16Relationship Between Organ Masses and Basal Metabolic Rate (BMR) in Tree Sparrows (Passer montanus)显示文摘BMR(basal metabolic rate),body mass and organ masses of tree sparrows(Passer montanus) were measured to analyze the correlation between organ masses and BMR in tree sparrows,and to evaluate the underlying physiological causes of difference in BMR. Adult tree sparrows were live-trapped by mist net in Qiqihar City,Heilongjiang Province(47 29'N,124 02'E) . The closed circuit respirometer was used to measure the metabolic rate(MR) ,and controlled the ambient temperature by using a water bath(±0.5℃) . Body masses were measured to the nearest 0.01 g before and after BMR measurements with a Sartorius balance(model BT25S) . The mean value was recorded as body mass. Wet and dry masses of several organs were measured,too. BMR was(4.276± 0.385) mL O 2 /(g h) and mean body mass was(18.522±0.110) g. Since not all the variables were normal distributed,a log 10-transformation of those variables was employed to linearize them,prior to analyses. Simple regression analyses indicated that most organ masses showed a significant high correlation with body mass. Both the small intestine and rectum masses were notable exception to that trend. The body-mass-adjusted residual analysis showed that only the kidney wet mass,brain mass,stomach mass,small mass and rectum wet mass correlated with BMR. In addition,correlations between several organ masses and BMR were observed. Because of the inter-correlations of organ masses,a principal component analysis(PCA) was performed to redefine the morphological variability. The first four components whose eigenvalues were greater than 1 could explain 75.2% variance of BMR. The first component,whose proportion reached 30.19%,was affected mainly by stomach mass,small intestine mass and rectum mass. Therefore,the results supported the hypothesis that BMR was controlled by some 'expensive metabolic' organs.LI Ming YIN Yajie NIE Chunyu QU Lina ZHNAG Guofa LIANG Yantao ZHAO Xiaoju LIU Jinsong 2011Journal of Northeast Agricultural University(English Edition)2011,18,4:4
17Effect of system parameters on the size distributions of hollow nickel microspheres produced by an ultrasound-aided electrical discharge machining process显示文摘Ultrasound-aided electric discharge machining(EDM) is an emerging technology for producing hollow nickel microspheres.This technology combines traditional EDM with the cavitation and vibration effects of ultrasound to produce hollow microspheres.In this paper,ultrasound-aided EDM was carried out in a kerosene medium(the working solution).The effects of various parameters on the sizes of microspheres were investigated using scanning electronic microscopy(SEM).Smileview software was used to measure the sizes of the microspheres.Originpro software was used for statistical analysis to determine the size distributions of the microspheres.To study the effects of the system parameters on the sizes of the microspheres,we first investigated the necessity of using an ultrasonic wave with EDM.After comparing the experimental results with and without the ultrasonic field,we found that ultrasound-induced cavitation and vibration effects reduced the diameters of the microspheres.We then studied the effects of several electrical parameters,including the arc current,pulse width,and gap voltage,on the sizes of the microspheres at an ultrasound frequency of 40 kHz.Smaller microspheres could be obtained by lowering the arc current,pulse width,and gap voltage.Yifan Liu Xianglong Li Fushi Bai Jian Chen Yantao Wang Nan Liu 2014Particuology2014,12,6:4
18Corrosion behavior of Mg-8Li-3Zn-Al alloy in neutral 3.5%NaCl solution显示文摘The corrosion behavior of Mg-8Li-3Zn-Al alloy was investigated in neutral 3.5%NaCl aqueous solution by morphology observation and electrochemical tests.The weight loss method was to measure the corrosion rate.The electrochemical results indicated that the corrosion resistance of Mg-8Li-3Zn-Al alloy in 3.5%NaCl solution is poorer than that in distilled water.The Cl-anion leads to the initiation and development of the corrosion pits.And the corrosion products are mainly Mg(OH)_(2).Lihui Yang Quantong Jiang Meng Zheng Baorong Hou Yantao Li 2016Journal of Magnesium and Alloys2016,4,1:4
19Numerical Simulation for Shallow Strata Stability of Coral Reef in the Southwest of Yongshu Reef(South China Sea)显示文摘In recent years, infrastructure construction on coral reefs has been increasingly developed. Therefore, the shallow strata stability of coral reefs in the South China Sea should be evaluated. This study aims to investigate the profiles for the shallow strata of coral reefs in the southwest of the Yongshu Reef, particularly in the hydrodynamic marine environment, and to establish a geological model for numerical simulation using Geo-Studio. The shallow strata of the coral reefs include mass gravel, sand gravel, mid-coarse sand, silty sand, fine sand, and reef limestone. The shallow reef slope near the lagoon is similar to a ‘layer cake', in which the side close to the sea is analogous to a ‘block cake'. The simulation results showed that coral reef stability depends on wave loads and earthquake strength and on the physical properties of coral reefs. The factor of safety for the outer reef is greater than 10.0 under static, wave, and seismic conditions; this indicated that the outer reefs were less affected by waves and earthquakes. However, the factor of safety next to the lagoon varied from 0.1 to 5.3. The variation was primarily caused by the thick strata of coral reefs close to the sea(reef limestone, typically with the thickness > 10 m and equivalent to a block). The soil and rock layers in the coral reef strata with thicknesses < 10 m showed weak engineering geological characteristics. Our findings can provide useful information to future construction projects on coral reefs.TANG Qinqin ZHANG Jinchang FENG Yingci LI Jian YAO Yantao SUN Jie ZHAN Wenhuan 2018Journal of Ocean University of China2018,17,4:3
20Recent progress of porcine milk components and mammary gland function显示文摘As the only nutritional source for newborn piglets,porcine colostrum and milk contain critical nutritional and immunological components including carbohydrates,lipids,and proteins(immunoglobulins).However,porcine milk composition is more complex than these three components.Recently,scientists identified additional and novel components of sow colostrum and milk,including exosomes,oligosaccharides,and bacteria,which possibly act as biological signals and modulate the intestinal environment and immune status in piglets and later in life.Evaluation of these nutritional and non-nutritional components in porcine milk will help better understand the nutritional and biological function of porcine colostrum and milk.Furthermore,some important functions of the porcine mammary gland have been reported in recent published literature.These preliminary studies hypothesized how glucose,amino acids,and fatty acids are transported from maternal blood to the porcine mammary gland for milk synthesis.Therefore,we summarized recent reports on sow milk composition and porcine mammary gland function in this review,with particular emphasis on macronutrient transfer and synthesis mechanisms,which might offer a possible approach for regulation of milk synthesis in the future.Shihai Zhang Fang Chen Yinzhi Zhang Yantao Lv Jinghui Heng Tian Min Lilang Li Wutai Guan 2019Journal of Animal Science and Biotechnology2019,10,1:2
