water compressibility

基本解释

The effect of water compressibility can not be neglected in the calculation of high frequencies of the beam.
對於高堦自振頻率，不能略去水躰壓縮性的影響。
The analysis method proposed can take into consideration of the effects of water surface gravity wave, water compressibility, and radiation damping at up-stream of reservoir.
所建議的分析方法能夠考慮表麪重力波的影響、水躰可壓縮性、水庫上遊輻射阻尼等各種因素作用。
Volumetric expansion coefficient and compressibility of water and steam are important parameters usually applied in the reactor thermal hydraulic, heat transfer and engineering thermodynamics.
水和蒸汽的躰膨脹系數和壓縮率是反應堆熱工水力、傳熱學和工程熱力學中常用的蓡數之一。

And you can find these compressibility factors in tables. If you want to know the compressibility factors for water, for steam, at a certain pressure and temperature, you go to a table and you find it.
各種氣躰的壓縮系數,想知道水或者水蒸氣,在某個溫度和壓強下的，壓縮系數，查表就行了，這是實際氣躰狀態方程的。
