我们继续在[11]中进行的多孔介质和自由流体流动之间的表面边界条件的研究。根据多孔介质中平均压力梯度的方向，斜向或垂直于表面，可能出现两种不同的现象。给出了不同流动区域和边界条件匹配的一般结果，并给出了实例。本文详细地研究了压力梯度为法向时的界面层。
We continue the study undertaken in [11] of boundary conditions at the surface between a porous medium and a free fluid flow. Two different kinds of phenomena may appear, according to the direction of the averaged gradient of pressure in the porous medium, oblique or normal to the surface. General results about the matching of the different flow regions and boundary conditions are given, as well as examples. The interface layer in the case of a normal gradient of pressure is studied in detail.
