| 摘 要： | 研究基于模型故障诊断中的测量点优选问题。首先，分析了模型故障诊断中导致诊断效率低下的原因。在此基础上，开发了４种优选测量点的诊断技术，在诊断过程中避免不必要的测试，从而提高了诊断效率，一个典型诊断系统的诊断过程表明，测点范围在原有基础上可缩成１／３到１／２左右。

| Abstract: | This paper studies the selection problem of measuring points in model based diagnosis. First, we analyze the causes of low efficiency in model based diagnosis, and then ,four diagnosis methods to optimal selecting measuring points are developed which avoid inefficient testing in diagnosis process to increase diagnosis efficiency. The diagnosis result of a typical diagnosis system shows that the number of measuring points can reduce to two thirds or half of original one. |
