摘　　要：针对航天电子系统中的电子元器件选用的途径———采用抗辐射加固器件和采用高性能商用器件进行了比较分析;阐述了空间飞行器采用抗辐射加固器件的优点和存在的问题,探讨了采用高性能商用器件的几种途径,抗辐射加固、冗余设计、筛选测试,以及存在的问题和面临的风险;以神舟四号飞船中商用器件的使用作为筛选测试的空间应用实例,给出了其在轨飞行的试验结果;并提出了商用器件的筛选测试必将成为商用器件空间应用的一个新的发展趋势。This paper analyses the two components selection approaches of using the radiation-hardened components and Commercial-Off-the-Shelf (COTS) components in space electronic systems, expounds the advantages and the problems of radiation-hardened components used in spacecraft, and discusses the several approaches, the problems and risks of COTS components in space application. Through the several approaches such as redundant design, radiation-hardened design, or screening and test, COTS components can be used to meet the requirements of high performance for spacecraft. As the application example of the screening and test of COTS, the onboard experimental results of Chinese Shenzhou-4 spaceship with a COTS are presented. The screening and test of COTS components will become a new tendency of COTS in space application.
