| 1 | Mathematical prototypes for collocating geostationary satellites显示文摘Collocating geostationary satellites sharing the same position is much demanded for satellite operation recently,the separation strategies are adopted to safeguard the satellites collocated of leaving the relative distance beyond collision with different sets of orbit parameters.This paper presents the mathematical prototypes which establish the allowable relative distance with uncertainty of orbital determination(OD),as well as the orbital element offset for each pair of collocated satellites,and puts forward algorithms to build such relationship to face the challenge of putting three satellites sharing the same position,the algorithms to allocate the longitude,eccentricity and inclination for each satellite are also given to ascertain that the mathematical prototypes are the guide specification to design collocation strategy for geostationary satellites. | LI HengNian GAO ZhaoZhao LI JiSheng LI QuanJun XUE Dan LI DongLin | 2013 | Science China(Technological Sciences)2013，56，5： | 6 |
| 2 | On the technologies of Hα imaging spectrograph for the CHASE mission显示文摘The Hα imaging spectrograph(HIS) is the scientific payload of the first solar space mission, the Chinese Hα solar explorer(CHASE), supported by the China National Space Administration(CNSA). The CHASE/HIS achieves, for the first time in space, Hα spectroscopic observations with high spectral and temporal resolutions. Separate channels for the raster scanning mode(RSM) and continuum imaging mode(CIM) are integrated into one, and a highly integrated design is achieved through multiple folding of the optical path and ultra-light miniaturized components. The design of HIS implements a number of key technologies such as high-precision scanning of the optical field of view(FOV), high-precision integrated manufacturing inspection, a large-tolerance pre-filter window, and full-link solar radiation calibration. The HIS instrument has a pixel spectral resolution of 0.024 ? and can complete a full-Sun scanning within 46 s. | Qiang Liu Hongjiang Tao Changzheng Chen Chengshan Han Zhe Chen Gui Mei Liang Yang Qinglong Hu Hongwei Xin Xiansheng Li Hongyu Guan Donglin Xue Mingchao Zhu Changhong Hu Qinghua Ha Yukun He Cheng Fang Chuan Li Zhen Li | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 2 |

| 4 | Oxidation behaviors of carbon fiber reinforced multilayer SiC–Si_(3)N_(4) matrix composites显示文摘Oxidation behaviors of carbon fiber reinforced SiC matrix composites(C/SiC)are one of the most noteworthy properties.For C/SiC,the oxidation behavior was controlled by matrix microcracks caused by the mismatch of coefficients of thermal expansion(CTEs)and elastic modulus between carbon fiber and SiC matrix.In order to improve the oxidation resistance,multilayer SiC–Si_(3)N_(4) matrices were fabricated by chemical vapor infiltration(CVI)to alleviate the above two kinds of mismatch and change the local stress distribution.For the oxidation of C/SiC with multilayer matrices,matrix microcracks would be deflected at the transition layer between different layers of multilayer SiC–Si_(3)N_(4) matrix to lengthen the oxygen diffusion channels,thereby improving the oxidation resistance of C/SiC,especially at 800 and 1000℃.The strength retention ratio was increased from 61.9%(C/SiC–SiC/SiC)to 75.7%(C/SiC–Si_(3)N_(4)/SiC/SiC)and 67.8%(C/SiC–SiC/Si_(3)N_(4)/SiC)after oxidation at 800℃for 10 h. | Xiaolin DANG Donglin ZHAO Tong GUO Xiaomeng FAN Jimei XUE Fang YE Yongsheng LIU Laifei CHENG | 2022 | Journal of Advanced Ceramics2022，11，2： | 1 |

| 8 | Skeletal muscle cell apoptosis following motor nerve injury versus sensory nerve injury显示文摘Skeletal muscle atrophy inevitably occurs in denervated skeletal muscle,and cell apoptosis plays an important role in skeletal muscle atrophy and degeneration.The present study established rat models of simple nerve injury by transecting the ventral or dorsal spinal nerve root and observed rat skeletal muscle cell apoptosis following simple motor nerve injury versus simple sensory nerve injury.Following skeletal muscle denervation for 10 weeks,cell apoptosis was detected in skeletal muscle,which was accompanied by obvious changes in rat behavior and electrophysiological responses.In addition,changes in cross-sectional area and average gray-scale of motor endplates of the gastrocnemius muscle were analyzed following sciatic nerve injury and motor nerve injury.Cell nuclei in denervated skeletal muscle tissue were more densely arranged than in normal skeletal muscle tissue.Cell nuclei were most dense in the sciatic nerve injury group,followed by the motor nerve injury group and the sensory nerve injury group.Fas/FasL expression and the number of apoptotic cells increased in denervated skeletal muscle,and apoptosis-related changes were observed.These findings suggested that motor and sensory nerves provided trophic actions following skeletal muscle and motor nerve injury,resulting in a greater influence on skeletal muscle atrophy than sensory nerve injury.Therefore,reconstruction of motor nerves should be preferentially considered for treating denervation-induced skeletal muscle atrophy. | Zhao, Lei Xu, Ruisheng Jiang, Shenyang Lue, Guangming Yan, Zhiqiang Sun, Junming Wang, Ling Xue, Ye Jiang, Donglin | 2011 | Neural Regeneration Research2011，6，3： | 0 |
