compressional wave meaning in Chinese

压缩波

There are two kinds of elastic waves in solids a compressional wave and a transverse wave .
在固体中有两类弹性波，一类是压缩波，另一类是横波。
Centered compressional wave
有心压缩波
Numerical results show that if appropriate delay times of sources are exerted on elements of phased array , direction of acoustic beam radiated from the phased array can be steered so that the refracted compressional wave and the refracted shear wave can be excited effectively
结果表明，只要在相控线阵的各阵元之间施加合适延迟时间的激励信号，就可以调整辐射器的辐射声束的方向，以有利于激发滑行纵波和滑行横波；只要采用相对较低的频率或使用加权相控线阵，就可以增大相控线阵的辐射主瓣角宽，以利于在任意地层有效激励滑行纵波。
