compressibility

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DPPC单分子膜在高膜压时之可压缩性小，因的压缩，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赖于地层流体粘和压缩性，是为地层孔隙、渗透率和射孔孔眼半径的函数。
