The difference in weight divided by the density of the liquid is the connected, or effective, pore volume.

前后两次重量的差值除以流体密度就得到样品中连通孔隙（也就是有效孔隙）的体积。

The continuum equation with conserved volume type was used to avoid divergence because of the big difference in density between gas and liquid.

采用了体积守恒形式的连续性方程，以防止由于气液两相密度差大而引起的数值求解中的不收敛现象。

To separate the liquid and gas phase, the separator makes use of the difference in density between them, and takes advantage of ESP high speed rotating, which used to power a separating device.

液气分离器就是充分利用电泵机组的高转速、气体和液体之间悬殊的密度差异进行液气离心分离。
