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

文中还对测误差作了析和估计,并介绍了测次波方法。

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

针对定长入射流，得到个自治动力系统，给出它次波共振叉图。
