摘　　要：推理机是专家系统的重要组成部分,直接影响专家系统的实用性和判断的正确性。文章探讨了农机液压系统故障诊断专家系统的推理机实现问题,研究了基于故障树理论的不精确推理方法,经过系统开发验证,该推理方法应用于故障诊断专家系统中,具有较高的诊断效率和准确性。Reasoning mechanism which affects application and correctness oi expert system is an important element of expert system. The paper introduces, reasoning mechanism of expert system in hydraulic system of farming machine. The paper studies, not precisely reasoning method based on fault tree theory in reasoning mechanism. According to the testifying of exploration of the expert system, the reasoning method has high diagnosing efficiency and correctness when it is applied in fault diagnosing expert system.
