| 1 | In-situ lunar dust deposition amount induced by lander landing in Chang’E-3 mission显示文摘China first in-situ lunar dust experiment is performed by a lunar dust detector in Chang’E-3 mission. The existed dust(less than 20 μm in diameter) properties, such as levitation, transportation and adhesion, are critical constraints for future lunar exploration program and even manned lunar exploration. Based on the problems discussed above, the in-situ lunar dust detector is originally designed to characterize dust deposition properties induced by lander landing as a function of environmental temperature, solar incident angle and orbit short circuit current on the northern Mare Imbrium, aiming to study lunar dust deposition properties induced by lander landing in depth. This paper begins with a brief of introduction of Chang’E-3 lunar dust detector design,followed by a series of experimental analysis of this instrument under different influencing factors, and concludes with lunar dust mass density deposition amount observed on the first lunar day is about 0.83 mg/cm^2, which is less than that observed in Apollo 11 mission because the landing site of Chang’E-3 has the youngest mare basalts comparing with previous Apollo and lunar landing sites. The young geologic environment is less weathered and thus it has thinner layer of lunar dust than Apollo missions’;hence, the amount of kicked-up lunar dust in Chang’E-3 mission is less than that in Apollo 11 mission. | ZHANG HaiYan WANG Yi CHEN LiPing ZHANG He LI CunHui ZHUANG JianHong LI DeTian WANG YongJun YANG ShengSheng LI XiongYao WANG WeiDong | 2020 | Science China(Technological Sciences)2020，63，3： | 9 |
| 2 | Calibration of Mars Energetic Particle Analyzer (MEPA)显示文摘The first Mars exploration mission of China(Tianwen-1)is scheduled to be launched in 2020;a charged particle telescope,the Mars Energetic Particle Analyzer(MEPA),is carried as one of the payloads on the orbiter.The MEPA is designed to measure solar energetic particles(SEPs)and galactic cosmic rays(GCRs)in the near-Mars space and in the transfer orbit from Earth to Mars.Before the launch,the MEPA was calibrated in ground experiments with radioactive sources,electronic pulses,and accelerator beams.The calibration parameters,such as energy conversion constants,threshold values for the triggers,and particle identification criteria,were determined and have been stored for onboard use.The validity of the calibration parameters has been verified with radioactive sources and beams.The calibration results indicate that the MEPA can measure charged particles reliably,as designed,and that it can satisfy the requirements of the Tianwen-1 mission. | ShuWen Tang Yi Wang HongYun Zhao Fang Fang Yi Qian YongJie Zhang HaiBo Yang CunHui Li Qiang Fu Jie Kong XiangYu Hu Hong Su ZhiYu Sun YuHong Yu BaoMing Zhang Yu Sun ZhiPeng Sun | 2020 | Earth and Planetary Physics2020，4，4： | 2 |

| 4 | Study on Pars Orbitalis Symmetry of UCLP Patients in Mixed Dentition Period显示文摘[Objectives] To analyze pars orbitalis symmetry of UCLP patients in mixed dentition period,and provide better theoretical basis for studying craniofacial shape and clinical treatment. [Methods]3 D reconstruction of CBCT images of 20 UCLP patients in mixed dentition period was conducted,and 13 mark points were selected from 3 D image for fixed-point measurement to analyze 3 D shape of pars orbitalis. [Results]( i) Horizontal symmetry of pars orbitalis. The width of pars orbitalis of UCLP patients at sites So,Lo,Oi,Or,So F,Z of fracture side was all equal to that at nonfracture side,and there was not statistical difference( P > 0. 05).( ii) Sagittal symmetry of pars orbitalis. Sagittal development of pars orbitalis of UCLP patients at sites So,Lo,Oi,Or,So F,Z of fracture side was equal to that at nonfracture side,and there was not statistical difference( P > 0. 05).( iii) Vertical symmetry of pars orbitalis. The height of pars orbitalis of UCLP patients at sites So,Lo,Oi,So F,Z of fracture side was higher than that at nonfracture side,and there was not obvious statistical difference( P > 0. 05).[Conclusions] There was not significant asymmetry in pars orbitalis of UCLP patients in mixed dentition period. | Ran LI Cunhui FAN Pinyi YAO Xinying HAN Xiaoxu FANG Zhonghui TIAN Xiaolin XU | 2018 | Medicinal Plant2018，9，1： | 0 |
| 5 | Comparative effects of rosuvastatin and atorvastatin on the risk of new-onset diabetes mellitus in patients with acute coronary syndrome receiving percutaneous coronary intervention:a retrospective cohort study显示文摘Background:Statins are frequently prescribed to reduce cardiovascular morbidity and mortality by lowering low-density lipoprotein cholesterol levels.However,the use of statins leads to an increased incidence of new-onset type 2 diabetes mellitus(NODM).Our study aims to compare the effect of rosuvastatin versus atorvastatin on NODM in patients with acute coronary syndrome(ACS)who underwent percutaneous coronary intervention(PCI)within 18 months of follow-up.Methods:A retrospective cohort study was conducted on patients with ACS who underwent PCI and were treated with rosuvastatin or atorvastatin between June 2012 and June 2017.The survival functions between the 2 groups were estimated using the Kaplan-Meier method and compared using the log-rank test with NODM as the endpoint.Cox proportional hazards models were used to calculate hazard ratios(HRs)and 95%confidence intervals(CIs)for the risk factors of NODM.Results:In total,220 patients received rosuvastatin and 168 atorvastatin.The cumulative incidence of NODM in the rosuvastatin group was lower but did not reach statistical significance,compared with that in the atorvastatin group(7.27%vs.12.50%,respectively;log-rank P=0.08).Using Cox proportional hazards models,baseline fasting blood glucose level was associated with a statistically significant increase in the risk of NODM(HR:4.56;95%CI:2.83–7.36;P<0.01).Conclusion:Long-term use of moderate rosuvastatin had a similar incidence of NODM compared with atorvastatin in patients with ACS receiving PCI. | Cunhui Jia Rui Tian Mengzhi Zong Fangyun Luan Wenjun Wang Chuanbao Li | 2022 | Emergency and Critical Care Medicine2022，2，4： | 0 |
