本文研究了在近连续介质条件下，同时存在压力梯度和温度梯度的稀薄气体平面Poillille流动。计算一般气体-气体和气体-表面的分子相互作用。通过变分技术明确计算了对称Onsager矩阵的二阶滑移和唯象系数。滑移速度和努森层的贡献，质量和热流的第二个对称矩阵描述。
Plane Poiseuille flow of a rarefied gas was studied in the presence of both a pressure and a temperature gradient under near continuum conditions. Calculations are performed for general gas–gas and gas–surface interactions of the molecules. The second‐order slip and the phenomenological coefficients of the symmetric Onsager matrix were explicitly calculated by variational techniques. The slip velocity and the contributions of the Knudsen layer to mass and heat flows are described by a second symmetric matrix.
