<正>本文在磨削火花温度信号特征分析的基础上，构成二维模式向量，并按模式向量的分布，用势能函数，在自学过程中形成判别函数。研究结果表明，用势能判别函数对磨削烧伤能作出正确的判别。

On the base of characteristic analysis of grinding sparks temperature,this paper forms atwo-dimensional vector.Then,according to the behavior of the vector distribution, potential functionis generated during self-learning process.Research results prove that the grinding burn is correctly classified by the funct.
