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性小，因而过度的，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.

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