potential density meaning in Chinese

势位密度
位势密度

In connection with the difference and distribution characteristic of the samples in sample space rs based on dga , a new self - adapted weight fuzzy omean clustering model of fault diagnosis of the power transformer based on the potential function is proposed . meanwhile , from the aspect of geometry characteristic of fc - divided in s dimension sample space , a method is proposed for the purpose of getting an effective adjacent radius , adaptive cluster number c and original cluster center of x sample set . for the diagnosis sample x , the property measure and diagnosis rule are proposed , which under the condition of potential density function that determine c number of optimal fuzzy cluster p1
根据以变压器dga数据为特征量的样本空间各样本差异特性以及样本在空间r ~ s的分布特性，首次提出了基于势函数自适应加权的变压器绝缘故障诊断的模糊c -均值聚类模型；同时，从s维样本空间的f ~ c -划分几何特性出发，提出了一种求取样本集的类势有效邻域半径和自适应求取聚类数和聚类中心初值的方法；对一个待诊断样本，设计了基于类势密度函数意义下的属性测度和诊断准则。
