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性小，因而过度的压，致单分子膜的崩塌。

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.

结现场试验,根据直线电泵运动特性,综考虑了液体的可压性、魏氏效应、液体连续流动条件和球阀的动力特性,建立了直线电泵球阀运动规律的精确运动微分方程组。
