摘　　要：利用前人所提出的对应态基团贡献法(Corresponding State Group Contribution,简称CSGC),回归了包括烷烃、烯烃、炔烃、酮、酯、萘、环氧化合物、含磷化合物、含硫、含氮、含硅等20类291种纯物质(共2,042个数据点)在不同温度下的液体黏度值,得到94个基团对临界温度和临界压力的贡献值以及方程的11个模型参数,总平均相对误差为6.13%.并且用10种未参与回归的物质(共79个数据点)对方程进行了验证,平均误差为67.9%.An exist equation that combined corresponding-state and group-contribution method is used to estimate liquid viscosity of pure compounds, 94 Group-contribution parameters and 11 model parameters were obtained by correlating experimental liquid viscosity at different temperature （ a total of 2042 data points ） of 291 compounds 20 classes including Alkanes, Alkenes, Alkynes, Alkone, Esters, Naphthalene, Epoxy, as well as compounds containing Sulfur, Nitrogen, Phosphorus, Silicon, et al.The overall average deviation is 6.13%.The average deviation is 6.79% for estimation of 10 （a total of 79 data points ） compounds beyond regression range using the obtained parameters.
