本文根据分子动力学理论和Lennard-Jones（m-6）族三参数相互作用势的关系，对稀薄中性气体氢-甲烷混合物输运性质的实验数据进行了分析和归纳。采用加权非线性最小二乘法联合处理，恢复了9个电位参数。计算了200-1500 K温度区间内的粘度、互扩散系数和热扩散因子的参考数据表。使用参数误差矩阵评价了整个浓度区间内参比数据的误差，包括纯组分的误差。
An analysis and generalization of experimental data on transport properties based on the relations of molecular-kinetic theory and three-parameter interaction potentials of the Lennard-Jones (m–6) family have been performed for the mixture of rarefied neutral gases "hydrogen–methane." Nine parameters of the potentials have been restored in joint data processing using the weight nonlinear least-squares method. Tables of reference data for viscosity, the interdiffusion coefficient, and the thermal diffusion factor have been calculated in the temperature interval 200–1500 K. Errors of reference data in the entire interval of concentrations, including those of pure components, have been evaluated using the matrix of parametric errors.
