However, because the compressibility of DPPC monolayer is low at high surface pressure, DPPC monolayer is easy to cause film collapsing due to overcompression.

然而DPPC单分子膜在高膜压时之可压缩性小，因而过的压缩，会导致单分子膜的崩塌。

The minimum underbalance is independent of viscosity and compressibility and of reservoir fluids.It is a function of the formation porosity, permeability and radius of perforation channels.

最小测试压差不是依层体压缩性，而是为层孔隙、渗透率射孔孔眼半径的函数。

The condensability of liquid,the Westphal's effect and the continuous flow condition are not only comprehensively considered,but also the dynamic property of the ball valve being established.

结合现场试验,根据直线电机采油泵运动特性,综合考虑了液体的可压缩性、魏氏效应、液体连续动条件球阀的动力特性,建立了直线电机采油泵球阀运动规律的精确运动微分方程组。
