The effect is termed harmonic distortion . 这种作用就称为谐波畸变。
We have stated a rule for consonance in terms of the coincidence of harmonics . 我们已经叙述了用谐波的符合来表示谐合的规则。
The time harmonics can be considered as voltages of higher frequencies applied to the windings . 时间谐波可以看作是施加在绕组上的较高频率的电压。
These stray currents usually have a higher frequency (50-60h2 harmonics) than those used in the ip frequency technique . 这些游散电流的频率(5060H2及其谐波)通常比IP频率域法中用的频率要高。
