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单分子在高时之可小，因而过度，会导致单分子塌。

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,根据直线电机采泵运动特,综合考虑了液体可、魏氏效应、液体连续流动条件和球阀动力特,建立了直线电机采泵球阀运动规律精确运动微分方程组。

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.

最小测试差不是依赖于地层流体粘度和，而是为地层孔隙度、渗透率和射孔孔眼半径函数。
