摘　　要：确定性方法在测发控系统故障诊断专家系统中的应用,先由专家给出每个规则和原始证据的确信度因子,经网络推理,把原始证据确信度因子与规则组合确信度因子,沿推理网络传播给非原始证据,求出其解。其在不确定性推理网络中采用Min和Max算子分别表示证据的合取和析取的逻辑组合,并给出相应组合函数。The certainty-fact method was applied to the fault-diagnose expert system in test and emission system. All the rules and the certainty factors of original evidence were given by experts at first, and then, the original evidence certainty factors and the rule combination certainty factors were spread through the net to unoriginal evidence through the net inferences; at last, the conclusion could be gained. In the indefinite inference net, the Min and Max arithmetic operators separately figured the logical combination of the ＂and＂ and ＂or＂ operation of the evidence, and the relevant combinational function was given.
