However, because of its nonlinear characteristics, the switching power supply resulting input current contains a large number of odd harmonics, which cause serious harmonic pollution for the grid.
然而由于其非线性的特性，导致其输入电流中含有大量奇次谐波，对电网造成了严重的谐波污染。

The completeness and higher-order squeezing properties of generalized odd and even coherent states of a Q-deformed non-harmonic oscillator are investigated.
给出了Q变形的非简谐振子广义奇偶相干态的完备性证明，并且研究了它们的高阶压缩特性。
