非均匀介质中粒子运动唯象方程中动力学系数的对称关系在气体动力学理论框架内得到了证明。这些系数表征了热泳和热极化现象。通过具有滑移边界条件的流体动力学，可以计算热极化效应的大小。将理论计算与最近的热极化实验研究进行了比较。
Symmetry relations for the kinetic coefficients in the phenomenological equations of particle motion in non-uniform media are proven within the framework of the kinetic theory of gases. These coefficients characterize the phenomena of thermophoresis and thermal polarization. By means of hydrodynamics with slip boundary conditions the magnitude of the thermal polarization effect is calculated. A comparison of the theoretical calculations with recent experimental investigations of thermal polarization is carried out.
