本文给出了Ne-氦、Ne-Ar两种二元混合体系粘度的绝对测定结果，以及三种纯组分粘度的绝对测定结果。测量是在20°C和30°C下借助我们的高精度摆盘粘度计进行的；它们覆盖了高达35atm的压力范围(密度从0到0.09g/cm~3)。对于Ne-He混合物，密度效应基本上可以以与温度无关的线性校正的形式表达，对于Ne-Ar混合物，密度效应可以以二次校正的形式表达，两者都适用于过量粘度Δμ=μ-μ0，其中μ0只是温度的函数。
The paper gives the results of the absolute determination of the viscosity of two binary systems of mixtures: neon—helium and neon—argon, together with those of the viscosity of the three pure components. The measurements were performed with the aid of our high‐precision oscillating‐disk viscometer at 20° and 30°C; they covered a range of pressures up to 35 atm (densities from 0 to 0.09 g/cm3).The density effect can be expressed, essentially, in the form of a temperature‐independent, linear correction in the case of the Ne–He mixtures, and in the form of a quadratic correction in the case of Ne–Ar mixtures, both applied to the excess viscosity Δμ = μ—μ0 in which μ0 is a function of temperature only.
