Abstract: In view of fuzzy knowledge itself intrinsic relation，one kind of mixed inference technology is proposed which unifies fuzzy inference and reversion inference.This paper introduces the design thought of this technology，realizes the algorithm with fuzzy knowledge，gives emphasis to elaborate the inference process which the fuzzy inference and the reversion inference unifies，realizes one more ideal and not definite inference，which effectively enhances the efficiency of inference machine.

Key words: fuzzy inference, reversion inference, fuzzy rules

摘要： 针对模糊知识的内在联系，提出了一种模糊推理与逆向推理相结合的混合推理技术，介绍了该技术的设计思想，结合模糊知识实现了算法，重点论述了模糊推理与逆向推理相结合的推理过程，实现了一种较为理想的不确定性推理方法，有效地提高了推理机的执行效率。
