摘　　要：针对安全仪表系统的各种安全评估方法适用性不明确的问题,基于白盒测试思想把安全评估方法抽象成具有特定功能的模块,测试该模块的过程就相当于衡量各种安全评估方法适用性的过程。最后,由比较结果给出各种安全评估方法的适用范围及其在特定环境下的置信度。Considering the uncertainty of various safety analysis techniques for safety instrument systems （SIS） , a white box testing-based solution to it was proposed to abstract safety assessment methods into special modules for testing,i, e. the process of judging applicability of various safety analysis techniques. The comparision results prove the application scope of various safety analysis techniques and their confidence degree in special environment.
