本文报道了用双泡装置在0°-120°C温度范围内测定了四个霓惰性气体二元系的扩散系数。实验值可用公式He-Ne，log10D12 = 1.631 log10T − 4.0051；Ne-Ar，log10D12 = 1.672 log10T − 4.6357；Ne-Kr，log10D12 = 1.757 log10T − 4.9332；Ne-Xe，log10D12 = 1.690 log10T − 4.8308来描述。目前的数据与其他工作人员的结果以及通过研究粘度系数的组成关系而得出的扩散系数值符合得很好。从导热系数的组成依赖关系得出的值大体上是一致的，但这种方法提供的扩散系数数据几乎不像粘度那样可靠。
Diffusion coefficients of all four neon–noble‐gas binary systems are reported as determined with a two‐bulb apparatus over the temperature range o°‐120°C. The experimental values, reduced to 1 atm pressure and trace composition of the heavier component, can be described by the expressions He–Ne, log10D12 = 1.631 log10T − 4.0051; Ne–Ar, log10D12 = 1.672 log10T − 4.6357; Ne–Kr, log10D12 = 1.757 log10T − 4.9332; Ne–Xe, log10D12 = 1.690 log10T − 4.8308. The present data are in favorable accord with the results of other workers and with diffusion coefficient values that are derived from studies of the composition dependence of the viscosity coefficient. Values derived from the composition dependence of the thermal conductivity coefficient are in fair agreement in general, but this method does not provide nearly as reliable a means of obtaining diffusion coefficient data as does viscosity.
