首先提出将容错功能与实时功能相结合的响应系统概念及基于响应系统的软件容错支撑软件系统，其次，提出能克服N版本致命缺点即双重错误的基于一致性恢复块的软件容错方案最后通过由4台微机构成的仿真系统验证了基于响应系统的软件容错支撑软件系统的可行性．
First of all, the conception of response system which combines fault-tolerant function and real-time function and software fault tolerant support software system based on response system are proposed. Secondly, the software fault tolerance scheme based on consistency recovery block which can overcome the fatal defect of N- The simulation system of 4 computers verified the feasibility of software fault tolerant support software system based on response system.
