摘　　要：空间环境中影响嵌入式星载计算机的主要因素包括温度、湿度、气压、光照、电磁干扰和空间高能粒子的辐射等;随着我国空间探测事业的发展,人们对星载系统可靠性的要求越来越高;容错技术是提高星载计算机系统可靠性的重要方法,为保证容错设计的正确性和容错机制的效率,需要采用辅助的技术对容错系统进行验证;故障注入技术是评测星载计算机容错机制的一种有效方法。The impact of space environment on--board computer embedded key factors including temperature, humidity, pressure, light, electromagnetic interference and high energy particles of space radiation. With the development of space exploration, people on the reliability of satellite systems have become increasingly demanding. Fault-tolerant technology is to improve the reliability of computer systems onboard an important method for fault--tolerant design to ensure the accuracy and efficiency of fault--tolerant mechanisms, need to adopt technology-assisted verification of fault--tolerant systems. Fault injection evaluation board computer technology is an effective method for fault tolerance.
