低压气体粘度的实验数据及计算方法的研究

Study on experimental data and calculation methods for viscosity of dilute gases

作者首先对有关低压气体粘度的文献进行了系统检索,对现有实验数据及计算方法的现状进行了分析,整理出能基本反映当前水平的有关化合物的实验数据,选出了当前较好的数种计算方法。根据化合物结构决定物性的原则,研究了不同计算方法对各种结构类型化合物的适用性。据此对650种化合物的低压气体粘度,选用尽可能好的方法进行了计算,并对计算结果进行了讨论。

Based on a systematic searching of literatures about viscosities of dilute gases,an analysis on the status quo of the available experimental data and calculation methods was carried out. Thus,the experimental data,as a reflection of the present art, for the related compounds were sorted out and a set of currently acceptable calculation methods picked out. The applicability of these methods to compounds of different structures was studied according to the principle that the physical property of a compound is dependent on its structure. Dilute gas viscosities were calculated therefrom for 650 compounds by using the preferred methods as far as possible,and brief comments on the calcultated data were also given.
