摘要
给出一种专家系统中的推理方法，它将逐步匹配的推理方法转化为逻辑值的数值计算，避免了逐步匹配的弱点。其推理时间至多为Ｏ（ｎ２），推理空间为Ｏ（ｎ２）。并在ＰＣ机上实现这种推理方法。
An inference method in the expert system was proposed, which transformed the step by step matching inference method into the numerical computation of logical value and thus avoided the former′s weakness. The inference time is O(n 2) at most and the inference space is O(n 2). This inference method has been implementated in PC computer.
