摘　　要：为方便测试性试验过程的实施,针对测试性验证试验中故障样本不可注入或注入成本太高的问题,提出了一种故障样本等价的计算方法。在对故障样本进行功能等价划分和测试等价划分的基础上,考虑到两个等价划分的不足,对所涉及的三种关联矩阵进行了定义,并根据测试点上不同测试对应的功能属性设计了一种满足实际需求的故障样本等价算法,并用实例说明了该方法的计算过程和可行性。Aiming at the problem that the fault sample injection cost is too high or the fault sample cannot be injected in testable verifiable tests, a calculating method of fault sample equivalence was presented for the sake of test and verification during the testing process. Based on the function equal division and the test equal division of the fault sample, the deficiency in the two equal division me- thods was taken into account, the three related matrixes were defined, and a fault sample equivalence algorithm was designed according to different functional properties corresponding to different tests at the test points. The calculating process was illustrated by the example.
