| 4 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan 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 CongZhan Liu 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 Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

| 6 | Inflammation and tumor progression:signaling pathways and targeted intervention显示文摘Cancer development and its response to therapy are regulated by inflammation,which either promotes or suppresses tumor progression,potentially displaying opposing effects on therapeutic outcomes.Chronic inflammation facilitates tumor progression and treatment resistance,whereas induction of acute inflammatory reactions often stimulates the maturation of dendritic cells(DCs)and antigen presentation,leading to anti-tumor immune responses.In addition,multiple signaling pathways,such as nuclear factor kappa B(NF-kB),Janus kinase/signal transducers and activators of transcription(JAK-STAT),toll-like receptor(TLR)pathways,cGAS/STING,and mitogen-activated protein kinase(MAPK);inflammatory factors,including cytokines(e.g.,interleukin(IL),interferon(IFN),and tumor necrosis factor(TNF)-a),chemokines(e.g.,C-C motif chemokine ligands(CCLs)and C-X-C motif chemokine ligands(CXCLs)),growth factors(e.g.,vascular endothelial growth factor(VEGF),transforming growth factor(TGF)-P),and inflammasome;as well as inflammatory metabolites including prostaglandins,leukotrienes,thromboxane,and specialized proresolving mediators(SPM),have been identified as pivotal regulators of the initiation and resolution of inflammation.Nowadays,local irradiation,recombinant cytokines,neutralizing antibodies,small-molecule inhibitors,DC vaccines,oncolytic viruses,TLR agonists,and SPM have been developed to specifically modulate inflammation in cancer therapy,with some of these factors already undergoing clinical trials.Herein,we discuss the initiation and resolution of inflammation,the crosstalk between tumor development and inflammatory processes.We also highlight potential targets for harnessing inflammation in the treatment of cancer. | Huakan Zhao Lei Wu Guifang Yan Yu Chen Mingyue Zhou Yongzhong Wu Yongsheng Li | 2021 | Signal Transduction and Targeted Therapy2021，6，8： | 11 |
| 7 | Artificial intelligence in drug design显示文摘Thanks to the fast improvement of the computing power and the rapid development of the computational chemistry and biology,the computer-aided drug design techniques have been successfully applied in almost every stage of the drug discovery and development pipeline to speed up the process of research and reduce the cost and risk related to preclinical and clinical trials.Owing to the development of machine learning theory and the accumulation of pharmacological data, the artificial intelligence(AI) technology, as a powerful data mining tool, has cut a figure in various fields of the drug design, such as virtual screening,activity scoring, quantitative structure-activity relationship(QSAR) analysis, de novo drug design, and in silico evaluation of absorption, distribution, metabolism, excretion and toxicity(ADME/T) properties. Although it is still challenging to provide a physical explanation of the AI-based models, it indeed has been acting as a great power to help manipulating the drug discovery through the versatile frameworks. Recently, due to the strong generalization ability and powerful feature extraction capability,deep learning methods have been employed in predicting the molecular properties as well as generating the desired molecules,which will further promote the application of AI technologies in the field of drug design. | Feisheng Zhong Jing Xing Xutong Li Xiaohong Liu Zunyun Fu Zhaoping Xiong Dong Lu Xiaolong Wu Jihui Zhao Xiaoqin Tan Fei Li Xiaomin Luo Zhaojun Li Kaixian Chen Mingyue Zheng Hualiang Jiang | 2018 | Science China(Life Sciences)2018，61，10： | 10 |
| 8 | Diversity of arbuscular mycorrhizal fungal spore communities and its relations to plants under increased temperature and precipitation in a natural grassland显示文摘Arbuscular mycorrhizal fungi(AMF)form mutualisms with most plant species,and therefore,understanding how AMF communities will respond to climate change is essential for predictions of changes in plant communities.To evaluate the impact of global climate change on AMFs and plant-AMF interactions in a natural grassland in Inner Mongolia,both artificial warming and watering treatments were assigned to experimental plots.Our results indicate that(1)warming and precipitation significantly affected the relative spore abundance of abundant sporulating AMF species;(2)the relative abundance of weak sporulating AMF species and AMF diversity decreased under experimental warming;(3)evidence was found that the composition of the AMF community in a given year might be correlated with plant community composition in the following year;and(4)grasses and forbs showing different preferences to Claroideoglomus etunicatum or Ambispora gerdemannii dominated plots.Our results imply that climate change appears to induce changes in AMF assemblages with knock-on effects on grassland plant communities.AMF communities may play a much more important role than we have thought in the responses of ecosystem to global climate changes. | SUN XiuFeng SU YuanYing ZHANG Ying WU MingYu ZHANG Zhe PEI KeQuan SUN LiFu WAN ShiQiang LIANG Yu | 2013 | Chinese Science Bulletin2013，58，33： | 6 |
| 9 | Measurements of ^(134)Cs and ^(137)Cs in urine and estimation of the internal dose of an adult exposed to the Chernobyl Accident显示文摘To estimate the internal dose of a Chinese visiting scholar internally contaminated because of the Cherno- byl Accident, the contents of 134Cs and 137Cs in urine were measured using a Ge(Li) γ-spectrometer. The internal doses were calculated based on data from the ICRP Publications. The effective doses from 134Cs and 137Cs were estimated to be 61 μSv and 98 μ Sv, respectively. The sum of 159 μSv was lower than the total effective dose (310 μSv), from the inhalation and ingestion of natural radionuclides. The dose of 131I was also reviewed referring to the UNSCEAR 2000 Report. The equivalent effective dose of 131I was estimated to be 2.9 mSv, 18 times more than the amount of 134Cs and 137Cs. Therefore, it is considered that the earlier estimation of internal doses of 131I is important in evaluating radiation injuries from a nuclear reactor accident. | ZHAO Shuquan HUANG Shibin LIU Shiming HU Heping WU Mingyu XIANG Xiqiao ZHU Guoying | 2007 | Nuclear Science and Techniques2007，18，2： | 5 |
| 10 | Tunable Co/ZnO/C@MWCNTs based on carbon nanotube-coated MOF with excellent microwave absorption properties显示文摘The development of global information technology makes human life intelligent,and the large-scale use of various electronic devices increases the electromagnetic radiation in the surrounding environment.This has created a requirement for the development of high-performance electromagnetic wave absorbers to eliminate electromagnetic pollution.However,the preparation of electromagnetic wave absorbers with excellent electromagnetic loss capability remains a great challenge.Here,we present a method to prepare Co/ZnO/C@MWCNTs(CZC@M)composites by pyrolysis of ZnCo-MOF@MWCNTs(MOF@M).Specifically,MWCNTs are uniformly distributed on the CZC surface to form multiple heterogeneous interfaces,which will lead to an increase in polarizability.In addition,changing the amounts of MWCNTs in the composite can modulate its dielectric constant and impedance matching properties.Impressively,at only 10%sample content,the minimum reflection loss of-41.75 d B and the maximum effective absorption bandwidth of 4.72 GHz are obtained at thicknesses of 2.4 mm and 2.2 mm,respectively.Overall,the results reported in this work provide a new design strategy for the synthesis of high-performance electromagnetic wave absorbers with potential applications in the elimination of electromagnetic pollution. | Zirui Jia Mingyue Kong Bowen Yu Yingzhuo Ma Jiaying Pan Guanglei Wu | 2022 | Journal of Materials Science & Technology2022，，32： | 5 |
| 11 | Distribution, sources and burial fl ux of sedimentary organic matter in the East China Sea显示文摘Distribution of total organic carbon(TOC),total nitrogen(TN),stable isotope ratio of organic carbon and nitrogen(δ13 C andδ15 N)in 31 surface sediments were examined to quantitatively discriminate the source and burial of sedimentary organic matter(SOM)in the East China Sea(ECS).Results show that high content of TOC and TN occurred in the southern inner shelf and the northeast area due to the transport of organic matter(OM)from the Changjiang(Yangtze)River southwards by the Zhejiang Fujian Coastal Current(ZFCC)and the delivery from the old Huanghe(Yellow)River estuary by the Subei Coastal Current(SbCC),respectively.The signifi cant relationship of TOC to clay provided evidence that the fi ne-grained sediment was the primary carrier for SOM from the inner shelf to open sea.The TN varied proportionally to the TOC with the neglected intercept,suggesting that most of nitrogen measured was related to the SOM and the infl uence of the sorption of inorganic nitrogen was insignifi cant.The seaward enrichment ofδ13 C and seaward depletion of C/N andδ15 N illustrated the decrease of terrestrial OM(TOM)and the increase of marine OM(MOM).The close of average C/N ratio to the Redfi eld ratio indicated the minor role of terrestrial plant debris in the SOM.Distribution of bulk OM properties was ascribed to the terrestrial and marine input by the shelf circulation and phytoplankton with the contributions of 76.1%MOM and 23.9%TOM to SOM,respectively.The burial fl ux of OC ranged within 0.34–7.56 mg/(cm 2∙a)(averaged 2.80 mg/(cm 2∙a))and enriched along the shore and in the fi ne-grained area,manifesting the signifi cant input of the land-based sources and the eff ect of shelf mud depositional process on the fate of SOM.The sharp seaward decrease of burial fl uxes of terrestrial and marine OC gave evidences that the majority of organic carbon were settled in the inner shelf with the small fraction of them further transported eastwards. | WU Xiaodan WU Bin JIANG Mingyu CHANG Fengming NAN Qingyun YU Xinke Saren Gaowa | 2020 | Journal of Oceanology and Limnology2020，38，5： | 5 |
| 12 | Influence of nanoparticle concentrations on flow boiling heat transfer coefficients of Al_2O_3/R141b in micro heat exchanger by direct metal laser sintering显示文摘Al_2O_3/R141 b + Span-80 nanorefrigerant for 0.05 wt.% to 0.4 wt.% is prepared by ultrasonic vibration to investigate the influence of nanoparticle concentrations on flow boiling heat transfer of Al_2O_3/R141 b + Span-80 in micro heat exchanger by direct metal laser sintering. Experimental results show that nanoparticle concentrations have significantly impact on heat transfer coefficients by homogeneity test of variances according to mathematical statistics. The heat transfer performance of Al_2O_3/R141 b+ Span-80 nanorefrigerant is enhanced after adding nanoparticles in the pure refrigerant R141 b. The heat transfer coefficients of 0.05 wt.%, 0.1 wt.%, 0.2 wt.%, 0.3 wt.%and 0.4 wt.% Al_2O_3/R141 b + Span-80 nanorefrigerant respectively increase by 55.0%, 72.0%, 53.0%, 42.3% and 39.9% compared with the pure refrigerant R141 b. The particle fluxes from viscosity gradient, non-uniform shear rate and Brownian motion cause particles to migrate in fluid especially in the process of flow boiling. This migration motion enhances heat transfer between nanoparticles and fluid. Therefore, the heat transfer performance of nanofluid is enhanced. It is important to note that the heat transfer coefficients nonlinearly increase with nanoparticle concentrations increasing. The heat transfer coefficients reach its maximum value at the mass concentration of 0.1% and then it decreases slightly. There exists an optimal mass concentration corresponding to the best heat transfer enhancement. The reason for the above phenomenon is attributed to nanoparticles deposition on the minichannel wall by Scanning Electron Microscopy observation. The channel surface wettability increases during the flow boiling experiment in the mass concentration range from 0.2 wt.% to 0.4 wt.%. The channel surface with wettability increasing needs more energy to produce a bubble. Therefore, the heat transfer coefficients decrease with nanoparticle concentrations in the range from 0.2 wt.% to 0.4 wt.%. In addition, a new correlation has been proposed by fitting the experimental data considering the influence of mass concentrations on the heat transfer performance. The new correlation can effectively predict the heat transfer coefficient. | Jianyang Zhou Xiaoping Luo Cong Deng Mingyu Xie Lin Zhang Di Wu Feng Guo | 2017 | Chinese Journal of Chemical Engineering2017，25，12： | 4 |
| 13 | Acute carbon monoxide poisoning in Shandong, China: an observational study显示文摘Background: Carbon monoxide (CO) poisoning remains a major cause of accidental injuries and multiple studies have indicated that CO is also associated with significantly severe or long-term toxicity to the central nervous system. Given that CO poisoning causes serious morbidity and mortality, a better understanding of epidemiological features and clinical characteristics of acute CO poisoning in China is crucial.Methods: We collected the clinical data of acute CO poisoning in patients between November 2019 and April 2020 across Shandong province, China and analyzed its characteristics focusing on the weekly amount and the severity of the confirmed cases.Results: A total number of 21,088 acute CO poisoning cases were diagnosed. The overall incidence of acute CO poisoning was approximately 0.021%. On severity rankings, 63% of confirmed cases (n=13,378) were mild, 27%(n=5635) were moderate, and 10% (n=2075) were severe. Interestingly, the coastal cities had more confirmed cases than the inland/suburban areas in Shandong. Meanwhile, the number of confirmed cases was negatively correlated with the local mean daily temperature (P=0.0167).Conclusions: Mild acute CO poisoning cases accounted for the majority of all confirmed cases during the winter of 2019. In Shandong province, which is located in east China, residents of the coastal cities are more susceptible to CO poisoning than residents of inland cities. | Lina Zhang Di Wu Mingyue Xu Yonghui Bian Youcun Wang Guangkai Gao Qing Sun | 2022 | Chinese Medical Journal2022，，13： | 4 |
| 14 | rAAV/ABAD-DP-6His attenuates oxidative stressinduced injury of PC12 cells显示文摘Our previous studies have revealed that amyloid β(Aβ)-binding alcohol dehydrogenase(ABAD) decoy peptide antagonizes Aβ42-induced neurotoxicity. However, whether it improves oxidative stress injury remains unclear. In this study, a recombinant adenovirus constitutively secreting and expressing Aβ-ABAD decoy peptide(rAAV/ABAD-DP-6His) was successfully constructed. Our results showed that rAAV/ABAD-DP-6His increased superoxide dismutase activity in hydrogen peroxide-induced oxidative stress-mediated injury of PC12 cells. Moreover, rAAV/ABADDP-6His decreased malondialdehyde content, intracellular Ca2+ concentration, and the level of reactive oxygen species. rAAV/ABAD-DP-6His maintained the stability of the mitochondrial membrane potential. In addition, the ATP level remained constant, and apoptosis was reduced. Overall, the results indicate that rAAV/ABAD-DP-6His generates the fusion peptide, Aβ-ABAD decoy peptide, which effectively protects PC12 cells from oxidative stress injury induced by hydrogen peroxide, thus exerting neuroprotective effects. | Mingyue Jia Mingyu Wang Yi Yang Yixin Chen Dujuan Liu Xu Wang Lei Song Jiang Wu Yu Yang | 2014 | Neural Regeneration Research2014，9，5： | 3 |
| 15 | The Variation of Stone Cell Content in 236 Germplasms of Sand Pear(Pyrus pyrifolia)and Identification of Related Candidate Genes显示文摘Stone cells have been described to substantially influence pear fruit quality,as lignin and cellulose are the main components of stone cells.However,there are limited studies on the relationship between the variation and molecular basis of stone cells,lignin and cellulose content among different pear varieties.Here,to reveal the variation of stone cell content within different cultivated species,we collected 236 germplasms of sand pear(Pyrus pyrifolia)at 50 days after flower blooming(DAFB),the key stage of stone cell formation.In our results,we measured the content of stone cells,lignin and cellulose and found that these contents ranged from2.82%to 29.00%,8.84%to 55.30%and 11.52%to 30.55%,respectively.Further analysis showed that the variation coefficient of stone cell,lignin and cellulose content was 39.10%,28.03%and 16.71%,respectively.Additionally,a significant correlation between stone cell,lignin and cellulose content were detected,and the correlation coefficient between the contents of stone cell and lignin(0.912)was higher than between the contents of stone cell and cellulose(0.796).Moreover,the average lignin content(29.73%)was higher than the average cellulose content(18.03%)in stone cells in pear fruits,indicating that lignin is the main component of stone cell in pears.Finally,on the basic of the transcriptome data,we identified 10 transcription factors belonging to bHLH,ERF,MYB,and NAC transcript families,which might be involved in lignin formation in stone cells.qRT-PCR experiments verified coincident trends between expression of candidate genes and stone cell content.This research laid foundation for future studies on genetic variation of stone cells in pear fruits and provided important gene resources for stone cell regulation. | Jiaying Zhang Jiaming Li Cheng Xue Runze Wang Mingyue Zhang Kaijie Qi Jing Fan Hongju Hu Shaoling Zhang Jun Wu | 2021 | Horticultural Plant Journal2021，7，2： | 3 |
| 16 | Vegetation and soil wind erosion dynamics of sandstorm control programs in the agro-pastoral transitional zone of northern China显示文摘To combat soil erosion and desertification,large-scale sandstorm control programs have been put in place since 2000 in the agro-pastoral transitional zone of northern China.Vegetation dynamics as well as soil wind erosion control effects are very important for assessing the ecological success of sandstorm control programs in China.However,no comprehensive evaluation of vegetation dynamics and soil wind erosion control effects in this region has been achieved.In this study,we illustrate the vegetation and soil wind erosion dynamics of sandstorm control programs in the northern Shanxi Province using remote sensing data and soil wind erosion models.There was a significant increase in vegetation cover for 63.59% of the study area from 2001 to 2014 and a significant decrease for 2.00% of the study area.The normalized difference vegetation index (NDVI) showed that the largest increase occurred in autumn.Soil wind erosion mass decreased from 20.90 million tons in 2001 to 7.65 million tons in 2014.Compared with 2001,the soil wind erosion moduli were reduced by 43.05%,36.16%,and 62.66% in 2005,2010,and 2014,respectively.Spatially,soil wind erosion in most of the study area was alleviated between 2001 and 2014.The relationship between NDVI and soil wind erosion mass showed that the increased vegetation coverage reduced the soil wind erosion mass.In addition,wind was the main driving force behind the soil wind erosion dynamics.The results indicate that the vegetation coverage has increased and soil wind erosion mass has been reduced following the implementation of the sandstorm control programs.However,the ecological effects of the sandstorm control programs may vary over different periods.While the programs appear to be beneficial in the short term,there may be unintended consequences in the long term.Research on the sustainability of the ecological benefits of sandstorm control programs needs to be conducted in the future. | Zhitao WU Mingyue WANG Hong ZHANG Ziqiang DU | 2019 | Frontiers of Earth Science2019，13，2： | 2 |
| 17 | Safe and Stable Lithium Metal Batteries Enabled by an Amide-Based Electrolyte显示文摘The formation of lithium dendrites and the safety hazards arising from flammable liquid electrolytes have seriously hindered the development of high-energy-density lithium metal batteries.Herein,an emerging amide-based electrolyte is proposed,containing LiTFSI and butyrolactam in different molar ratios.1,1,2,2-Tetrafluoroethyl-2,2,3,3-tetrafluoropropylether and fluoroethylene carbonate are introduced into the amide-based electrolyte as counter solvent and additives.The well-designed amide-based electrolyte possesses nonflammability,high ionic conductivity,high thermal stability and electrochemical stability(>4.7 V).Besides,an inorganic/organic-rich solid electrolyte interphase with an abundance of LiF,Li3N and Li-N-C is in situ formed,leading to spherical lithium deposition.The formation mechanism and solvation chemistry of amide-based electrolyte are further inves-tigated by molecular dynamics simulations and density functional theory.When applied in Li metal batteries with LiFePO4 and LiMn2O4 cathode,the amide-based electrolyte can enable stable cycling performance at room temperature and 60℃.This study provides a new insight into the development of amide-based electrolytes for lithium metal batteries. | Wanbao Wu Yiyang Bo Deping Li Yihong Liang Jichuan Zhang Miaomiao Cao Ruitian Guo Zhenye Zhu Lijie Ci Mingyu Li Jiaheng Zhang | 2022 | Nano-Micro Letters2022，14，3： | 2 |
| 18 | The novel amyloid-beta peptide aptamer inhibits intracellular amyloid-beta peptide toxicity显示文摘Amyloid β peptide binding alcohol dehydrogenase (ABAD) decoy peptide (DP) can competitively antagonize binding of amyloid β peptide to ABAD and inhibit the cytotoxic effects of amyloid β peptide. Based on peptide aptamers, the present study inserted ABAD-DP into the disulfide bond of human thioredoxin (TRX) using molecular cloning technique to construct a fusion gene that can express the TRX1-ABAD-DP-TRX2 aptamer. Moreover, adeno-associated virus was used to allow its stable expression. Immunofluorescent staining revealed the co-expression of the transduced fusion gene TRX1-ABAD-DP-TRX2 and amyloid β peptide in NIH-3T3 cells, indicating that the TRX1-ABAD-DP-TRX2 aptamer can bind amyloid β peptide within cells. In addition, cell morphology and MTT results suggested that TRX1-ABAD-DP-TRX2 attenuated amyloid β peptide-induced SH-SY5Y cell injury and improved cell viability. These findings confirmed the possibility of constructing TRX-based peptide aptamer using ABAD-DP.

| 19 | Overview to the Hard X-ray Modulation Telescope (Insight-HXMT) Satellite显示文摘As China’s first X-ray astronomical satellite, the Hard X-ray Modulation Telescope (HXMT), which was dubbed as Insight-HXMT after the launch on June 15, 2017, is a wide-band(1-250 ke V) slat-collimator-based X-ray astronomy satellite with the capability of all-sky monitoring in 0.2-3 Me V. 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 |
| 20 | Effect of liquid-solid ratio on the morphology,structure,conductivity,and electromagnetic characteristics of iron particles显示文摘Using a ball-milling technique,polymorphous iron particles were prepared by changing only the liquid-solid ratioλ.Effects of λon their morphology,structure,conductivity,and electromagnetic properties were studied.The results show that an increase ofλfrom 0 to 0.25 causes a nonlinear decrease of the conductivity in the ranges of 88.50-2.25 S cm-1 and a regular variation of the electromagnetic parameters,corresponding to the as-obtained iron particles.This is ascribed to a combination of the increased shape anisotropy and the decreased fresh surface with active atoms deriving from the weakened welding-on action and the enhanced micro-malleation action in the ball-milling process.Hereinto,the iron flakes formed at wet-milling with λ=0.08-0.25 have lower conductivity,higher permittivity and permeability,and more excellent absorption property compared with the irregular iron particles obtained at dry-milling withλ=0.It is a consequence of the synergistic effect of dielectric relaxation loss,exchange energy and conductance loss originating from the flake-shape structures.This indicates that the morphology,structure,conductivity,and electromagnetic properties of the products can be effectively controlled by changingλ. | TONG GuoXiu HUA Qiao WU WenHua QIN MingYue LI LiangChao GONG PeiJun | 2011 | Science China(Technological Sciences)2011，54，2： | 2 |
