| 1 | 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 |
| 2 | 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 |
| 3 | Recent progress in fluorinated electrolytes for improving the performance of Li–S batteries显示文摘Lithium–sulfur(Li–S) batteries represent a 'beyond Li-ion' technology with low cost and high theoretical energy density and should fulfill the ever-growing requirements of electric vehicles and stationary energy storage systems. However, the sulfur-based conversion reaction in conventional liquid electrolytes results in issues like the so-called shuttle effect of polysulfides and lithium dendrite growth, which deteriorate the electrochemical performance and safety of Li–S batteries. Optimization of conventional organic solvents(including ether and carbonate) by fluorination to form fluorinated electrolytes is a promising strategy for the practical application of Li–S batteries. The fluorinated electrolytes, owing to the high electronegativity of fluorine, possesses attractive physicochemical properties, including low melting point,high flash point, and low solubility of lithium polysulfide, and can form a compact and stable solid electrolyte interphase(SEI) with the lithium metal anode. Herein, we review recent advancements in the development of fluorinated electrolytes for use in Li–S batteries. The effect of solvent molecular structure on the performance of Li–S batteries and the formation mechanism of SEI on the cathode and anode sides are analyzed and discussed in detail. The remaining challenges and future perspectives of fluorinated electrolytes for Li–S batteries are also presented. | Xiwen Wang Yuqing Tan Guohong Shen Shiguo Zhang | 2020 | Journal of Energy Chemistry2020，29，2： | 3 |

It was designed to perform pointing, scanning and gamma-ray burst(GRB)observations and, based on the Direct Demodulation Method (DDM), the image of the scanned sky region can be reconstructed.Here we give an overview of the mission and its progresses, including payload, core sciences, ground calibration/facility, ground segment, data archive, software, in-orbit performance, calibration, background model, observations and some preliminary results. | Shuang-Nan Zhang TiPei Li FangJun Lu LiMing Song YuPeng X u CongZhan Liu Yong Chen XueLei Cao QingCui Bu Zhi Chang Gang Chen Li Chen TianXiang Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong Yuan Yuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan Can Gungor ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge Ou JinLu Qu Na Sai RenCheng Shang GuoHong Shen Liang Sun Ying Tan Lian Tao YouLi Tuo Chen Wang ChunQin Wang GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BaiYang Wu BoBing Wu Mei Wu GuangCheng Xiao ShaoLin Xiong LinLi Yan JiaWei Yang Sheng Yang YanJi Yang QiBin Yi Bin Yuan AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang ShenYi Zhangs Shu Zhang Tong Zhang WanChang Zhang Wei Zhang WenZhao Zhang Yi Zhang YiFei Zhang YongJie Zhang Yue Zhang Zhao Zhang Zhi Zhang ZiLiang Zhang HaiSheng Zhao XiaoFan Zhao ShiJie Zheng JianFeng Zhou YuXuan Zhu Yue Zhu RenLin Zhuang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 2 |
| 5 | Biomimetic mineralization and cytocompatibility of nanorod hydroxyapatite/graphene oxide composites显示文摘Nanorod hydroxyapatite (NRHA)/graphene oxide (GO)composites with weight ratios of 0.4,1.5, and 5have been fabricated by a facile ultrasonic-assisted method at room temperature and atmospheric pressure. The chemical structure properties and morphology of the composites were characterized by field emission source scanning electron microscope,X-ray diffraction,transmission electron microscopy,and high-resolution transmission electron microscopy.The results indicate that the NRHA/ GO composites have an irregular surface with different degree wrinkles and are stable,and NRHA are well combined with GO.In addition,the biomimetic mineralization mechanism of hydroxyapatite on the NRHA/GO composites in simulated body fluid (SBF)is presented.The presence of a bone-like apatite layer on the composite surface indicate that the NRHA/GO composites facilitate the nucleation and growth of hydroxyapatite crystals in SBF for biomimetic mineralization.Moreover,the NRHA-1.5/GO composite and pure GO were cultured with MC3T3-E1cells to investigate the proliferation and adhesion of cells.In vitro cytocompatibility evaluation demonstrated that the NRHA/GO composite can act as a good template for the growth and adhesion of cells. Therefore,the NRHA/GO composite could be applied as a GO-based,free-template,non-toxic,and bioactive composite to substitute for a damaged or defect bone. | Peizhen Duan Juan Shen Guohong Zou Xu Xia Bo Jin | 2018 | Frontiers of Chemical Science and Engineering2018，12，4： | 2 |

| 13 | Proton belt variations traced back to Fengyun-1C satellite observations显示文摘We used historical data to trace trapped protons observed by the Fengyun-1C(FY-1C)satellite at low Earth orbits(~800 km)and chose data at 5–10 MeV,10–40 MeV,40–100 MeV,and^100–300 MeV from 25 March to 18 April 2000 to analyze the proton variations.Only one isolated strong storm was associated with a solar proton event during this period,and there was no influence from previous proton variations.Complex dynamic phenomena of proton trapping and loss were affected by this disturbance differently depending on the energy and L location.The flux of 5–10 MeV protons increased and created new trapping with a maximum at L^2.0,and the peak flux was significantly higher than that at the center of the South Atlantic Anomaly.However,at higher L,the flux showed obvious loss,with retreat of the outer boundary from L^2.7 to L^2.5.The increase in the 10–40 MeV proton flux was similar to that of the 5–10 MeV flux;however,the peak flux intensity was lower than that at the center of the South Atlantic Anomaly.The loss of the 10–40 MeV proton flux was closer to the Earth side,and the outer boundary was reduced from L^2.3 to L^2.25.For the higher energy protons of 40–100 MeV and 100–300 MeV,no new trapping was found.Loss of the 40–100 MeV protons was observed,and the outer boundary shifted from L^2.0 to L^1.9.Loss was not obvious for the 100–400 MeV protons,which were distributed within L<1.8.New proton trapping was more likely to be created at lower energy in the region of solar proton injection by the strong magnetic storm,whereas loss occurred in a wide energy range and reduced the outer boundary on the Earth side.Similar dynamic changes were observed by the NOAA-15 satellite in the same period,but the FY-1C satellite observed more complex changes in lower energy protons.These results revealed that the dynamic behavior of protons with different L-shells was due to differences in the pitch angle.Possible mechanisms related to new trapping and loss are also discussed.These mechanisms are very important for understanding the behavior of the proton belt in the coming solar cycle. | ChunQin Wang Zheng Chang XiaoXin Zhang GuoHong Shen ShenYi Zhang YueQiang Sun JiaWei Li Tao Jing HuanXin Zhang Ying Sun BinQuan Zhang | 2020 | Earth and Planetary Physics2020，4，6： | 1 |

| 17 | Investigation on the short-term outcome and prognostic impact of predisposition,and precipitants in inpatients with chronic liver disease from Chinese AcuTe on CHronic LIver FailurE(CATCH-LIFE)cohorts显示文摘Aim:The study aimed to investigate the short-term outcomes of hospitalized patients with chronic liver disease(CLDs)and assess the prognostic impact of predisposition and precipitants,which currently remains unclear.Methods:The study included 3970 hospitalized patients with CLDs from two prospective longitudinal multicenter studies(NCT02457637 and NCT03641872)conducted in highly endemic hepatitis B virus(HBV)areas.Competing risk analysis was used to evaluate the effect of predispositions,including the etiology and severity of CLDs and precipitants;on sequential 28,90,and 365-day liver transplantation(LT)-free mortality.Results:Among all enrolled patients,76.8%of adverse outcomes(including death and LT)within one year occurred within 90 days.Compared with alcoholic etiology,the association of HBV etiology with poorer outcomes was remarkably on the 28th day(hazard ratio[HR],1.81;95%confidence interval[CI],1.07-3.06;p=0.026);however,and dimin-ished or became insignificant at 90 days and 365 days.Cirrhosis increased the adjusted risk for 365-day(HR,1.50;CI,1.13-1.99;p=0.004)LT-free mortality when compared with noncirrhosis.In patients with cirrhosis,prior decompensation(PD)independently increased the adjusted risk of 365-day LT-free mortality by 1.25-fold(p=0.021);however,it did not increase the risk for 90-day mortality.Neither the category nor the number of precipitants influenced the adjusted risk of 28 or 90-day LT-free mortality.Conclusions:The 90-day outcome should be considered a significant endpoint for evaluating the short-term prognosis of hospitalized patients with CLD.Predisposing factors,other than etiology,mainly affected the delayed(365-day)outcome.Timely effective therapy for CLD etiology,especially antiviral treatments for HBV,and post-discharge long-term surveillance monitoring in cirrhotic patients undergoing PD are suggested to enhance disease management and reduce mortality. | Yan Zhang Wenting Tan Xiaobo Wang Xin Zheng Yan Huang Beiling Li Zhongji Meng Yanhang Gao Zhiping Qian Feng Liu Xiaobo Lu Jia Shang Yubao Zheng Weituo Zhang Shan Yin Wenyi Gu Tongyu Wang Jianyi Wei Zixuan Shen Guohong Deng Yi Zhou Yixin Hou Qun Zhang Shue Xiong Jing Liu Liyuan Long Ruochan Chen Jinjun Chen Xiuhua Jiang Sen Luo Yuanyuan Chen Chang Jiang Jinming Zhao Liujuan Ji Xue Mei Jing Li Tao Li Rongjiong Zheng Xinyi Zhou Haotang Ren Yu Shi Hai Li for the CATCH‐LIFE Study Investigators of Chinese(Acute‐on)Chronic Liver Failure(CLIF)Consortium(Ch‐CLIFC) | 2023 | Portal Hypertension & Cirrhosis2023，2，3： | 0 |

| 19 | Research on stability and Hopf bifurcation of marine ecosystem dynamics models显示文摘The predictability of marine ecosystem dynamics models is one of the most vital factors to limit their practical applications, of which the stability is the fundamental condition. In order to discuss the stability and Hopf bifurcation of marine ecosystem dynamics models, an approach based on a theorem termed dimension reduction was proposed and further applied in the mass-conservative nutrient-phytoplankton-zooplankton-detritus(NPZD) model in this paper. Results showed that the nonsingular equilibrium point of NPZD model was analytically stable in use of the dimension reduction theorem and the Hopf bifurcation might occur when model parameters changed along the threshold values. The analytical results of the NPZD model were further verified by numerical simulation in this study. It can be concluded that this approach based on the dimension reduction theorem is well applicable to the theoretical analysis of a kind of stability problems and Hopf bifurcation of massconservative systems. | SHI Honghua HU Long FANG Guohong WEI Zexun SHEN Chengcheng LIU Yongzhi | 2016 | Acta Oceanologica Sinica2016，35，4： | 0 |
| 20 | Physiological Responses of Dendrobium officinale under Exposure to Cold Stress with Two Cultivars显示文摘This study aimed to explore the cold tolerance of two cultivars of Dendrobium officinale(MG1,MG2)grown in different regions of China.Under-2℃ incubation,cultivar MG1 remained active after 3 d,and continued to grow after returning to room temperature.However,MG2 could only maintain its activity after 2 d treatment at−2℃,and the seedlings died with the low temperature treatment time.Investigation of the characteristics of the plants grown in the south(Hangzhou)or north(Zhengzhou)of China indicated that the leaves of MG1 also had reduced stomatal density,the highest thickness,and a compact microstructure.The contents of proline and soluble sugars were higher in MG1 than those in MG2.The cultivar MG1 had higher SOD enzyme activity than MG2,while CAT and POD activities in samples from Zhengzhou were higher than those from Hangzhou.The contents of polysaccharides and alkaloids in stems of in MG1 were higher than those in MG2,while the content of flavonoids in the Zhengzhou samples was higher than that in the Hangzhou samples.In addition,plant heights,stem diameters,and chlorophyll content were higher in MG1.Overall,MG1 had better cold resistance than MG2.MG1 is a cold tolerant cultivar with thick leaves and reduced stomatal density,higher contents of soluble sugars,proline,CAT,POD,polysaccharides,flavonoids and alkaloids,which together make it more adaptable to low temperatures.Thus,the cultivar MG1,with its demonstrated cold tolerance,can accordingly be grown on a large scale in cold regions,thereby expanding the available planting area for this important traditional medicinal plant to meet the increasing commercial demand for it. | Shuaishuai Zhang Jin Li Yongchang Shen Linda Nartey Korkor Qian Pu Jin Lu Balock Shakeela Dedong Kong Ou Li Guohong Zeng Xiufang Hu | 2020 | Phyton-International Journal of Experimental Botany2020，89，3： | 0 |
