摘　　要：研究数字化反应堆保护系统软件的可靠性对提高保护系统的整体可靠性具有重要的意义。本文在分析、整理HTR-PM保护系统软件开发过程中记录的测试数据基础上,研究并提出了基于错误严重程度的软件可靠性模型。软件测试过程中不同严重程度的错误其检测难度不同,导致检测率随时间的变化趋势不同,本文提出了严重程度比函数的概念以表述这一现象,并对不同严重程度错误的检测数据分别建模,使软件可靠性模型的预测结果更具有工程应用价值。The research on software reliability of digital reactor protection system（RPS）plays an important role to improve the reliability of RPS.Based on analyzing the fault data set collected during the software development of HTR-PM RPS,a new software reliability model involving the fault severity was studied and established.In the practice detecting faults with different severities usually have different levels of difficulty,and the trend of detecting rate with different severities varies with time.In this paper the severity ratio function（SRF）was proposed,and separate models were developed to deal with faults with different severities.This can achieve better prediction and reflect the software reliability in more aspects for engineering application.
