In the production practice, will encounter a large number of non-sine wave.
在生产实践中，会遇到大量的非正弦波。

Even if it worked with three-phase sine, three-phase line current would have non-sine aberrance and produce harmonic wave-electricity.
即使在三相正弦激励的作用下，三相线电流也将发生非正弦畸变，产生谐波电流。

In this paper, the functional influence of input voltage non-sine of Varible-frequency voltage source on Electric Power Dynamometer motor discussed. and methods of improving them were also given.
