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计,并介绍了测量分数次波的一种方法。

Resonance of surface waves of a given length is shown to be possible over bed waves with synchronous , subharmonic, or ultraharmonic wave lengths.

针对定长，得到一个自治动力系统，给出它的次波共振分叉图。
