行波

The external inspirator is available to drive the resonator to produce traveling wave.Under resonant frequency the distortion of resonator reached a peak.

外激励驱动方式可以使扁环型谐振产生有效行波分量，在谐振频率下，谐振综合变形量最大。

The spatial variation of seismic ground motions is produced primaryly by the three factors of geometric incoherency effect,wave-passage effect, and local site effect.

导致地震动空间变异性原因主要在于:几不相关性效应、行波效应、局场地条件效应。

Fluid is conveied to bit nozzel through drill string from pump is a transient state flowing with pressure wave, which makes the fluid jetted out from nozzel has certain pulsation.

从钻井泵经过钻输送到钻头喷嘴流体是一种瞬态流动，存在着压力行波，使从普通喷嘴射出流体有一定程度脉动。
