摘　　要：单粒子事件对航天工程的威胁越来越严重．研究星载计算机软件防护加固技术，在软件上采取抗干扰设计、容错设计、提高程序的自我保护能力，以减少由于单粒子事件引起的软错误、减少航天器故障、提高可靠性和安全性具有重要的意义．Single Event Upset is seriously imperilling spacecraft engineering. The technology of protecting with softwitre of the computer at space vehicle had been put forward. This paper lays emphasis on overcoming interference with software, fault tolerant technique, prigraming self -protecting and so on, for the space vehicle trouble and soft-error caused by SEU. That will has significance for reliability of spacecraft engineering.
