1·This model is equally valid in regions of compressional tectonics.

此模型同样适用于挤压构造地区。

2·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。

3·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。

4·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。

5·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。

6·An acoustic log that USES the attenuation of compressional and shear waves to locate fractures.

利用纵波和横波的衰减确定裂缝位置的一种声波测井方法。

7·The concept of tectonic level was initially put forward to describe the region of compressional deformation.

构造层次的概念最初是针对挤压变形区提出来的。

8·Sand box analog models have been proved to be an efficient tools for researching the compressional structure.

砂箱物理模拟实验已被证明是研究盆地挤压构造的有效工具。

9·And the velocity of slow compressional-wave (P-wave) is in direct proportion to the porosity and the density of fluid.

而慢纵波的速度则和孔隙度和流体的密度成正比。

10·For clean sandstone, the acoustic dispersion of compressional wave exists obviously when its porosity is more than 28%.

对纯砂岩，当孔隙度大于28%时存在明显纵波声频散。
