Wave distortion will occur when finiteamplitude ultrasonic waves propagate in elastic solids, resulting in the production of higher order harmonics.
有限振幅的超声波在固体中传播时会发生波形畸变,伴随着高次谐波的出现。

The finiteamplitude solitary waves in stratified fluids of finite depth, in which the density varies with depth in lower layer but keeps uniform in upper layer, are investigated.
