| 1 | 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 | Pharmacokinetics of magnesium lithospermate B after intravenous administration in beagle dogs显示文摘AIM: To develop a specific liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the pharmacokinetic study of magnesium lithospermate B (MLB), and study the pharmacokinetics of MLB after iv administration in beagle dogs.. METHODS: Each beagle dog was iv administered MLB 3, 6, and 12 mg/kg random. The serum drug concentration was determined by specific liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays. The pharmacokinetic parameters were calculated by Drug and Statistics version 1.0 program.RESULTS: The calibration curve for MLB was linear over a range of 16-4096 μg/L with coefficients of correlation>0.999. The intra- and inter-day precisions (CV) of analysis were <10 %, and accuracy ranged from 90 % to 113%. After iv administration of MLB at the doses of 3, 6, and 12 mg/kg, the CO values for MLB were estimated to be of 24, 47, and 107 mg/L, respectively. The AUC increased with the increasing doses for iv administration, and the mean AUC0-4 values were 109.3, 247.9, and 582.4 mg·min·L^-1, respectively. MLB was distributed and eliminated quickly from central compartment, the mean T1/2a values for MLB at doses of 3, 6, 12 mg/kg were 2.2, 2.7, and 2.9 rain,and the mean T1/2β values were 43, 42, and 42 min, respectively. CONCLUSION: This LC-MS/MS method is rapid, sensitive, and specific for the pharmacokinetic study of MLB. The kinetic process of MLB in beagle dogs in vivo was best fitted to a two-compartment model. For iv administration, the pharmacokinetic parameters of CO and AUC have good linearity among the doses, and MLB was distributed and eliminated quickly in beagle dogs. | Xiao-chuan LI, Chen YU, Wei-kang SUN, Gang-yi LIU, Jing-ying JIA, Yi-ping WANGDepartment of Pharmacology, Shanghai Institute of Materia Medica, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, Shanghai 201203 Central Laboratory, Shanghai Xuhui Central Hospital, Shanghai 200002, China | 2004 | Acta Pharmacologica Sinica2004，25，11： | 13 |
| 4 | Spatial and temporal distribution of acetochlor in sediments and riparian soils of the Songhua River Basin in northeastern China显示文摘The Songhua River Basin is a burgeoning agricultural area in the modern times in China.Particularly in recent years,increasing chemical fertilizers and pesticides have been applied with the development of agricultural production.However,the situation of nonpoint source pollution (NSP) from agricultural production in this basin is still obscure.In order to solve the problem,the occurrence and distribution of acetochlor in sediments and riparian soils of the Songhua River Basin before rain season and after rain season were investigated.In addition,total organic carbon was analyzed.The result showed that the concentration of acetochlor ranged from 0.47 to 11.76 μg/kg in sediments and 0.03 to 709.37 μg/kg in riparian soils.During the high flow period in 2009,the mean concentration was 4.79 μg/kg in sediments and 0.75 μg/kg in riparian soils,respectively.Similarly,the mean concentration was 2.53 μg/kg in sediments and 61.36 μg/kg in riparian soils,during the average flow period in 2010.There was a significant correlation between the concentration of acetochlor and total organic carbon in surface sediments.Moreover,the distribution of acetochlor in sediments of the Songhua River was significantly correlated to land use and topography of the watershed.The investigated data suggested that the concentration of acetochlor in the Songnen Plain and the Sanjiang Plain was higher than that in the other areas of the basin,and riparian buffering zones in these areas had been destroyed by human activities.The optimal agricultural measures to alleviate the contamination of pesticides should be adopted,including controlling agricultural application of acetochlor and ecological restoration of riparian buffering strips. | Xiaoyin Sun Qixing Zhou Wenjie Ren Xuhui Li Liping Ren | 2011 | Journal of Environmental Sciences2011，23，10： | 9 |
| 5 | Penetration characteristics of VLF wave from atmosphere into lower ionosphere显示文摘The factors affecting the reflection and transmission coefficient of the ionosphere have been analyzed.These factors include wave frequency,incident angle,geomagnetic inclination,electron density and collision frequency in the ionosphere.The ionosphere refractive index is also analyzed.The ionosphere above 70 km is considered to be homogeneous and anisotropic,and the reflection and transmission coefficient matrix is calculated using matrix method.Simultaneously the Booker quartic equation is solved to get the refractive index in the ionosphere.The results show that when the wave frequency is higher,it is easier to penetrate into the ionosphere from its bottom boundary and the propagation attenuation in the ionosphere is smaller.TE(traverse electric) wave and TM(traverse magnetic) wave can both penetrate into the ionosphere with a small incident angle,while TE wave can hardly transmit into the ionosphere when the incident angle is large.The transmission coefficient decreases as the geomagnetic inclination increases.TE and TM wave cannot penetrate into the ionosphere at magnetic equator.When the electron collision frequency is higher,it is easier for VLF wave to penetrate into the ionosphere and the attenuation of ordinary wave is weaker,which may be caused by the energy transportation between the waves and the particles.The ordinary(O) wave experiences severer attenuation than extraordinary(X) wave,and X wave is a penetration mode whereas O wave is a non-penetration mode in the ionosphere.All the results indicate that VLF wave with higher frequency is easier to penetrate into the ionosphere and to be recorded by the satellites at high latitude.It is hard for ULF and the lower frequency VLF wave to transmit into the ionosphere directly for the severe reflection and attenuation.It may transmit into the ionosphere with a small incident angle due to the nonlinear effect,for example,the interaction between the waves and the particles or cross modulation,and then propagate along the whistle duct with small attenuation.This work may be a preliminary theoretical exploration for the future calculation on the response of ground based VLF artificial transmitter in the ionosphere and further study on the seismic ionosphere coupling model. | Shufan Zhao Xuhui Shen Weiyan Pan Xuemin Zhang Li Liao | 2010 | Earthquake Science2010，23，3： | 8 |
| 6 | Intermetallic PtBi core/ultrathin Pt shell nanoplates for efficient and I stable methanol and ethanol electro-oxidization显示文摘The development of Pt-based core/shell nanoparticles represents an emerging class of electrocatalysts for fuel cells, such as methanol oxidation reaction (MOR) and ethanol oxidation reaction (EOR). Here, we present a one-pot synthesis approach to prepare hexagonal PtBi/Pt core/shell nan ostructure composed of an in termetallic PtiBii core and an ultrathi n Pt shell with well-defined shape, size, and composition.The structure and the synergistic effect among different components enhanced their MOR and EOR performanee. The optimized Pt2Bi nanoplates exhibit excellent mass activities in both MOR (4,820 mA·mgpt^-1) and EOR (5,950 mA·mgpt^1) conducted in alkaline media, which are 6.15 times and 8.63 times higher than those of commercial Pt/C, respectively. Pt2Bi nan opiates also show superior operati on durability to commercial Pt/C. This work may inspire the rational design and synthesis of Pt-based nanoparticles with improved performance for fuel cells and other applications. | Xiaolei Yuan Xiaojing Jiang Muhan Cao Lei Chen Kaiqi Nie Yong Zhang Yong Xu Xuhui Sun Yanguang Li Qiao Zhang | 2019 | Nano Research2019，12，2： | 7 |
| 7 | Field measurements of settling velocities of fine sediments in Three Gorges Reservoir using ADV显示文摘The Three Gorges Reservoir(TGR) is suffering from unexpected fine sediment deposition,to better understand the fine sediment transport processes,field measurements were conducted at the Zhongxian and Fengjie reaches.A method based on the sediment diffusion equation was proposed to measure the settling velocities using the Acoustic Doppler Velocimeter(ADV).The backscatter acoustic intensities(BSI) received from the ADV were calibrated against the sediment concentrations measured via water sampling,suggesting a linear relationship in double logarithmic coordinate system.The instantaneous sediment concentration was calculated using the derived relationship,and then the settling velocity was obtained through the proposed procedure.The settling velocities of the fine particles in the TGR were found to vary with the water depth.Most of the effective settling velocities were within the range of 0.1-10 mm/s,which were larger than those of the primary particles,indicating that the flocculation was likely to occur in the TGR.Additionally,it is suggested that the turbulent motion played an important role in the flocculation in the TGR. | Wenjie Li Shengfa Yang Jiang Hu Xuhui Fu Peng Zhang | 2016 | International Journal of Sediment Research2016，31，3： | 6 |
| 8 | Preparation of multi-color quantum dots and its application to immunohistochemical analysis显示文摘Quantum dots (QDs) have the potential to be used in the multiplexed bioanalysis for their unique property:multi-color QDs can be excited at the same single wavelength light. In this work,high quan-tum yield multi-color core/shell QDs were prepared. After being water-solubilized by amphiphilic polymer based on self-assembling,the QDs would be labeled by two different IgGs and used in the multiplexed biodetection. Fluorescence resonance energy transfer (FRET) should be avoided in the multiplexed biodetection. In this work,spectral analysis showed that no FRET appeared in water-soluble QDs modified by amphiphilic polymer. The immunofluorescence in vitro indicated that the QDs-IgGs bioconjugates had excellent species-specific detection ability with nearly non-specific binding. The setting of this model will help to support the application of multi-color QDs in the multiplexed bioanalysis communities. | ZHANG BingBo LIU XuHui LI DeNa TIAN Hui MA GuiPing CHANG Jin | 2008 | Chinese Science Bulletin2008，53，13： | 6 |

| 10 | NSHV trajectory prediction algorithm based on aerodynamic acceleration EMD decomposition显示文摘Aiming at the problem of gliding near space hypersonic vehicle(NSHV)trajectory prediction,a trajectory prediction method based on aerodynamic acceleration empirical mode decomposition(EMD)is proposed.The method analyzes the motion characteristics of the skipping gliding NSHV and verifies that the aerodynamic acceleration of the target has a relatively stable rule.On this basis,EMD is used to extract the trend of aerodynamic acceleration into multiple sub-items,and aggregate sub-items with similar attributes.Then,a prior basis function is set according to the aerodynamic acceleration stability rule,and the aggregated data are fitted by the basis function to predict its future state.After that,the prediction data of the aerodynamic acceleration are used to drive the system to predict the target trajectory.Finally,experiments verify the effectiveness of the method.In addition,the distribution of prediction errors in space is discussed,and the reasons are analyzed. | LI Fan XIONG Jiajun LAN Xuhui BI Hongkui CHEN Xin | 2021 | Journal of Systems Engineering and Electronics2021，32，1： | 6 |
| 11 | Investigation of ionospheric TEC changes related to the 2008 Wenchuan earthquake based on statistic analysis and signal detection显示文摘Ionospheric TEC(total electron content) time series are derived from GPS measurements at 13 stations around the epicenter of the 2008 Wenchuan earthquake.Defining anomaly bounds for a sliding window by quartile and 2-standard deviation of TEC values,this paper analyzed the characteristics of ionospheric changes before and after the destructive event.The Neyman-Pearson signal detection method is employed to compute the probabilities of TEC abnormalities.Result shows that one week before the Wenchuan earthquake,ionospheric TEC over the epicenter and its vicinities displays obvious abnormal disturbances,most of which are positive anomalies.The largest TEC abnormal changes appeared on May 9,three days prior to the seismic event.Signal detection shows that the largest possibility of TEC abnormity on May 9 is 50.74%,indicating that ionospheric abnormities three days before the main shock are likely related to the preparation process of the MS8.0 Wenchuan earthquake. | Jianyong Li Guojie Meng Min Wang Hua Liao Xuhui Shen | 2009 | Earthquake Science2009，22，5： | 6 |

| 13 | Influence of fault geometry and fault interaction on strain partitioning within western Sichuan and its adjacent region显示文摘There are several major active fault zones in the western Sichuan and its vicinity. Slip rates and seismicity vary on different fault zones. For example, slip rates on the Xianshuihe fault zone are higher than 10 mm/a. Its seismicity is also intense. Slip rates on the Longmenshan fault zone are low. However, Wenchuan Ms8.0 earthquake occurred on this fault zone in 2008. Here we study the impact of fault geometry on strain partitioning in the western Sichuan region using a three-dimensional viscoe- lastoplastic model. We conclude that the slip partitioning on the Xianshuihe-Xiaojiang fault presents as segmented, and it is related to fault geometry and fault structure. Slip rate is high on fault segment with simple geometry and structure, and vice versa. Strain rate outside the fault is localized around the fault segment with complex geometry and fault structure. Strain partitioning on the central section of the Xianshuihe-Xiaojiang fault zone is influenced by the interaction between the Anninghe-Zemuhe fault and the Daliangshan fault zone. Striking of the Longmenshan fault zone is nearly orthogonal to the direction of eastward extrusion in the Tibetan Plateau. It leads to low slip rate on the fault zone. | WANG Hui LIU Jie SHEN XuHui LIU Mian LI QingSong SHI YaoLin ZHANG GuoMin | 2010 | Science China Earth Sciences2010，53，7： | 5 |

| 15 | Thermally stable photoluminescence and long persistent luminescence of Ca3Ga4O9:Tb^3+/Zn^2+显示文摘A green long persistent luminescence(LPL) phosphor Ca_3 Ga_4 O_9:Tb^(3+)/Zn^(2+) was prepared. Ca_3 Ga_4 O_9 matrix exhibits blue self-activated LPL due to the creation of intrinsic traps. When Tb3+ is doped, the photoluminescence(PL) and LPL colors change from blue to green with their intensities significantly enhanced. The doping of Zn^(2+) evidently improves the PL and LPL performances of the Ca_3Ga_4O_9 matrix and Ca_3Ga_4O_9:Tb^(3+). The thermoluminescence(TL) spectra show that a successive trap distribution is formed by multiple intrinsic traps with different depths in the Ca_3 Ga_4 O_9 matrix, and the incorporation of Tb^(3+) and Zn^(2+) effectively increases the densities of these intrinsic traps. The existence of a successive trap distribution makes the Ca_3 Ga_4 O_9:Tb^(3+)/Zn^(2+) phosphor exhibit thermally stable PL and LPL, It is indicated that this phosphor shows great promise for the application such as high-temperature LPL phosphor. | Zhangwen Long Junhe Zhou Jianbei Qiu Qi Wang Dacheng Zhou Xuhui Xu Xue Yu Hao Wu Zhencai Li | 2018 | Journal of Rare Earths2018，36，7： | 4 |
| 16 | Neuritin promotes angiogenesis through inhibition of DLL4/Notch signaling pathway显示文摘Neuritin is a member of the neurotrophic factor family,which plays an important role in the promotion and development of the nervous system.Neuritin is also involved in angiogenesis.Neuritin was recently found to be a negative regulatory factor of the Notch 1 signaling pathway.Notch signaling pathway is known as a regulatory pathway of angiogenesis.Thus,neuritin may play a role in angiogenesis through the Notch signaling pathway.In the present study,we investigated the expressions of neuritin and Notch signaling pathway factors in the pulmonary vascular tissue.The results showed that neuritin expression was increased in the paraneoplastic vascular tissue and decreased in the lung cancer vascular tissue.The neuritin expression was increased with the increase of vascular tissue density,and a negative correlation between neuritin expression and delta-like ligand 4(DLL4)was identified in vascular tissues of lung cancer.Overexpression of neuritin in human umbilical vein endothelial cells(HUVECs)inhibited the expressions of Notch signaling pathway-associated factors,including DLL4,NICD,and Hes-1,and promoted the migration and tubular formation of HUVECs.In conclusion,our results indicated that neuritin is involved in angiogenesis and may play a role in angiogenesis through the Notch signaling pathway.This study provides a theoretical basis for clinical anti-angiogenesis therapy. | Li Yang Xuhui Wang Jiawei Sun Chunyan Liu Guoxiang Li Jingling Zhu Jin Huang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，6： | 4 |

| 18 | Simultaneous removal and oxidation of arsenic from water byδ-MnO 2 modified activated carbon显示文摘The ubiquitous arsenic in groundwater poses a great risk to human health due to its environmental toxicity and carcinogenicity.In the present work,a new adsorbent,δ-MnO2 modified activated carbon,was prepared,and its performance for the uptake of arsenate and arsenite species from aqueous solutions was investigated by batch experiments.Various techniques,including FESEM-EDX,p-XRD,XPS and BET surface area analysis,were employed to characterize the properties of the adsorbent and the arsenic adsorption mechanisms.The results showed thatδ-MnO2 covered on the surface and padded in the pores of the activated carbon.Adsorption kinetic studies revealed that approximately 90.1%and 76.8%of As(Ⅲ)and As(V),respectively,were removed by the adsorbent in the first 9 hr,and adsorption achieved equilibrium within 48 hr.The maximum adsorption capacities of As(V)and As(Ⅲ)at pH 4.0 calculated from Langmuir adsorption isotherms were 13.30 and 12.56 mg/g,respectively.The effect of pH on As(Ⅴ)and As(Ⅲ)removal was similar,and the removal efficiency significantly reduced with the increase of solution pH.Arsenite oxidation and adsorption kinetics showed that the As(Ⅴ)concentration in solution due to As(Ⅲ)oxidation and reductive dissolution of MnO2 increased rapidly during the first 12 min,and then gradually decreased.Based on the XPS analysis,nearly 93.3%of As(Ⅲ)had been oxidized to As(V)on the adsorbent surface and around 38.9%of Mn(Ⅳ)had been reduced to Mn(Ⅱ)after As(Ⅲ)adsorption.This approach provides a possible method for the purification of arsenic-contaminated groundwater. | Yulong Wang Hupeng Liu Shaofeng Wang Xuhui Li Xin Wang Yongfeng Jia | 2020 | Journal of Environmental Sciences2020，32，8： | 4 |
| 19 | In-flight observations of electromagnetic interferences emitted by satellite显示文摘Using the data from STAFF/TC-1, this paper for the first time analyzes the electromagnetic interferences of Chinese scientific satellite. The electromagnetic interference of satellite exists mainly below 30 Hz, but can extend to 190 Hz with an obviously decreasing power spectral density. The electromagnetic interferences at frequencies below 190 Hz have good correlation with the solar aspect angle. The electromagnetic interferences at frequencies between 190 and 830 Hz have also correlation with solar as-pect angle. However, the electromagnetic interferences at frequencies above 830 Hz have no correlation with the solar aspect angle. The correlation coefficient between solar aspect angel and electromagnetic interferences is around 0.90. The larger the solar aspect angle, the stronger the satellite electromagnetic interference. When the solar aspect angle increases from 90.6° to 93.6°, the electromagnetic interferences at frequencies <10 Hz increase by 8 times and those at frequencies 190―830 Hz increase by 60%. This close association of electromagnetic interferences with the solar aspect angle indicates that the solar aspect angle is the main factor to determine the electromagnetic interferences. The electromagnetic interferences of satellite in sunlight are larger than those in eclipse. The electro-magnetic interference produced by solar panel occupies about 87% in the low frequency band (<100 Hz) and 94% in the high frequency band (>100 Hz) of the total electromagnetic interference produced by satellite. These in flight observations of electromagnetic radiation of satellites will be very helpful to the designs of future satellites of space sciences or earthquake sciences. | CAO JinBin YANG JunYing YUAN ShiGan SHEN XuHui LIU YuanMo YAN ChunXiao LI WenZhen CHEN Tao | 2009 | Science China(Technological Sciences)2009，52，7： | 4 |
