我们研究胶体悬浮液中相对运动的性质。通过仔细区分吉布斯定义的混合物的热力学压力和达西在多孔介质中测量的压力，我们解决了不同实验的结果和解释之间的明显矛盾。我们表明，菲克和达西定律，两个经验方程被认为是描述不同的和互补的物理现象，实际上是一个单一的，统一的热力学方程，可以更普遍地用来描述胶体系统中的运输的特定限制。重要的是，这个方程涉及宏观可测量的量。我们用它来提供新的解释超滤实验。
We examine the nature of relative motion in colloidal suspensions. By distinguishing carefully between the thermodynamic pressure of a mixture, defined by Gibbs, and the pressure measured by Darcy in porous media, we resolve apparent contradictions between the results and interpretations of different experiments. We show that Fick’s and Darcy’s laws, two empirical equations thought to describe different and complementary physical phenomena, are in fact particular limits of a single, unifying thermodynamic equation which can be used more generally to describe transport in colloidal systems. Importantly, this equation relates macroscopically measurable quantities. We use it to provide new interpretations of experiments in ultrafiltration.
