The modulation index can be increased by using distorted wave forms that contain only triplen (multiples of three) harmonics.

通过使用只含有三谐波的波形作为载波可以提这个调节指数。

The error estimation of the quasi-synchronous sampling harmonics anal-ysis and the method used for measuring the subharmonics of periodic signalsare also discussed.

文中还对测量误差作了分析和估计,并介绍了测量分数谐波的一种方法。

In this superradiance harmonics, the temporal width of harmonics is extremely short, the ratio of high harmonic fundamental wave is much higher than the known superradiance harmonics.

在这种机制里，谐波脉冲的时间宽度极；谐波与基波的比例比已知的超辐射谐波得多。
