摘　　要：吸取神经网络和专家系统两种方法的优点、弥补各自的不足,把启发式规则推理和神经网络诊断方法进行有机集成,建立一个集成专家系统,更加准确地模拟人脑的真实思维过程。以火电厂化学水处理为例,在采集了充分的故障数据后,结合典型的故障经验数据,进行了故障诊断的仿真试验,并给出实际应用效果,以此说明了该故障诊断专家系统的实用性。Absorbing the merits of neural network and expert system, to make up for their shortcomings. Establishing an integrated expert system by integrating the heuristic rule inference and the neural network diagnosis method organically, in order to simulate human brain＇s real thinking process accurately. Expert system based on neural network for a thermal power plan. In addition, the paper gathered the data of water treartment in chemistry, combined with the typical fault data, then formulated the fault diagnosis and gived the practical application effect. At last the paper showed the practicability of the sistem.
