This model is equally valid in regions of compressional tectonics.

此模型同样适用于挤压构造地区。

Normally the shear velocity is about half of the compressional velocity.

一般地说横波速度大约是纵波速度的一半。

It is of importance to interpretations of seismic data from compressional basins.

这对于挤压型盆地中的地震资料解释具有重要意义。

The result shows that the principal compressional stress field is in the SW NE direction.

结果表明，该区域应力场主压应力方向为SW - NE向。

The compressional stress mainly comes from SW, and the NE direction ACTS as a resistance.

挤压应力主要来自南西方向、北东方向起阻挡作用。
