此外，表面波的形态及其演化还对初始扰动比较敏感。

Moreover, the shape and evolution are sensitive to initial disturbance.

表面波是一种沿两媒质之界面传播的波。

A surface wave is one that propagates along an interface between two media.

采用该传感器测试了激光超声表面波、兰姆波和纵波，获得了很好的波形。

The sensor was applied to detect several kinds of laser ultrasonic, such as surface acoustic wave, Lamb wave and longitudinal wave, well-defined waveforms were obtained.
