and measure the compressibility coefficient of the soil containing the hydrates of natural gas conveniently and accurately under different conditions, so the device is suitable for simulating the change rule of the compressibility of the soil containing the hydrates of natural gas under different working...
athe coefficient of volume compressibility is the slope of the volumetric water content function in the positive pore pressure range and in physical terms it describes how much a saturated soil volume will swell or shrink for a given change in pore pressure 容量压缩性系数是容量水含量作用的倾斜在...

The proposed estimates can also be used to find the equivalent bulk modulus of the fluid–air mixture in the partially saturated porous material. We note that if the fluid–gas mixture in the porous material is treated as a two-phase system, then the equivalent compressibility of the mixture ...
