By application of thermodynamics on the theory of microcirculation in tissues one must implicate the fact that both phenomena convection and diffusion through semipermeable membranes take place in "non opened" compartments. Based on this precondition the present paper shows that the known calculations by Kedem and Katchalsky and others are insufficient in order to describe the above mentioned processes and that the reflection coefficient delta is not relevant to the real movement of molecules through capillary walls. Furthermore, the basic equation of the microcirculation is to be improved by a diffusion component in order to represent a better approximation of the exchange situation in tissues.
通过将热力学应用于组织微循环理论，必须考虑到这样一个事实，即对流和通过半透膜的扩散这两种现象都发生在“非开放”隔室中。基于这一前提，本文表明，凯德姆和卡察尔斯基等人的已知计算不足以描述上述过程，且反射系数δ与分子通过毛细血管壁的实际运动无关。此外，微循环的基本方程需要通过一个扩散分量来改进，以便更好地近似组织中的交换情况。
