摘要
论文在建立推理机制之前，先将源故障案例进行分组并提取出相应的检索规则，同时对各油色谱组分进行权重赋值，最后利用欧式距离方法进行目标案例与源案例的匹配。通过该方式不但大大减少了匹配的次数，同时提高了旺配的正确率。
Before establishing the reasoning mechanism, the source fault cases were grouped and extract the corresponding retrieval rules, at the same time assign the weigths to gases dissolved in transformer oil, match target case and source case by euclidean distance method at last.In this way not only greatly reduces the number of matches at the same time to improve the accuracy rate of matching.
