ZN: Air compressioncoefficient in standard condition;
气体在标况下的压缩系数；
2
With water saturation going up (oil saturation going down), acoustic compressioncoefficient is becoming small.
随着含水饱和度的升高(含油饱和度的降低)，其声学压缩系数越小。
3
The soft soil has characteristics of high water content and low anti-shears strength and high compressioncoefficient and low penetrability and high sensitivity.
