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单分子膜在高膜时之可缩性小，因而过缩，会导致单分子膜崩塌。

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.

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