The fit is almost always partial rather than exact—and the echoes and patterns are often visible only at a distance.

即使共鸣，也仅是部分吻合而不是全部——共鸣的回响与发生形式经常只在一定范围内显现。

And then a method of partial discharge monitoring based on pulse current and a technique of fault diagnosis based on the minimum distance method to stator winding are presented.

接下来提出采用脉冲电流法完成定子放电故障信号的采集，应用基于最小距离法对定子局部放电样本进行故障识别。

And, coincidently, what is the partial of energy with respect to distance?

巧合的是，能量对距离的导数是什么？
