【摘要】 介绍了固体火箭发动机质量评判的特点。以带有两种典型伤情缺陷的固体火箭发动机为例 ,对主观 Bayes非精确推理方法在固体火箭发动机质量评判中的应用进行了分析研究 ,给出了非精确推理框图 ,并简要介绍了确定推理规则中的充分性度量 LS、必要性度量 LN和前提的可信度 C( E,S) ,以及计算多种伤情缺陷作用下发动机禁用的后验概率的方法更多还原

【Abstract】 The characteristics of the quality determination consultant for solid rocket motor are presented.Based on a solid rocket motor with two typical flaws and damages,analysis is carried out on the application of Bayes approximation reasoning in the quality determination consultant for solid motor,and the reasoning network is given.It is briefly introduced how to define the sufficiency measure ( LS ) and the necessity measure ( LN ) of the reasoning rules,the evidence credibility measure ( C(E,S) ),and how to use approximate reasoning to calculate the forbidden posterior probability of solid rocket motor with multiple flaws and damages.更多还原
