低渗透介质 meaning in Chinese

least permeable medium

The influence of the boundary on the seepage flooding in low permeability porous media ca n ' t be ignored when the thickness of boundary layer reaches a critical value . the larger the thickness of boundary layer is , the more obvious the nonlinear flow is . 4 . factors affecting boundary layer are studied systemically , the mathematical expression of porous flow based on the experiment is derived
吸附边界层的厚度大到一定程度将对低渗透介质中渗流规律产生影响，边界层厚度越大，非达西现象越明显； 4 、系统研究了影响边界层的因素，并在实验的基础上，推导了考虑边界层影响下的渗流力学表达式。
