| 摘 要： | 本文给出了作为发动机故障诊断前提条件的故障方程的严格定义，论述了故障方程中故障因子的独立性问题及故障方程的求解条件。这些论述对于正确建立故障方程、防止在引入故障因子问题上出现数学方法上和物理概念上的错误以及正确制定发动机故障诊断的技术方案具有重要意义。文中还对现有文献在这些问题上的不妥当观点进行了分析。

| Abstract: | The strict definition of fault equation which is the basis for engine fault diagnosis is given and the problems of the independence of fault factors and the conditions for resolving fault equation are discussed in the paper. These propositions are of great significance in correctly establishing fault equation, for avoiding mistakes in mathematics and physics in introducing fault factors, and for correctly working out the technical scheme for engine fault diagnosis. Some improper viewpoints on these problems are also analysed in the paper. |
