摘　　要：应用张克武气体氩模型理论微分方程 ,导出液体粘度理论方程 ,并据理论分析引出“正烷烃沸点下的粘度值相同”等定理、定则 .本法经以 2 4 0种无机、有机、极性与非极性等 3 8种不同结构类型的 1 42 8个实验数据检验 ,平均误差1 .85% .其精度比著名的vanVelzen Cardozo Langenkamp法高 9倍以上 ,达到实验容许误差范围内 .解决了近百年来化学工程与凝聚态物理学交叉科学领域内无法精确计算的液体粘度这一关键难题 .建立了通用的精确的液体粘度理论模型 .Zhangkewu′s theoretical equation for gas viscosity (ZTEGV) derived from the differential equation for a model of argon gas is here extended to the liquid . A theoretical equation of liquid viscosity μ 2 is derived. One theorem and 2 rules are obtained by logical reasoning. The equation can be applied to both polar and nonpolar liquids, the average error is 1.85% from 1428 experimental data from 240 compounds of 38 structural types. Its accuracy is over 9 times higher than that of the famous van Velzen et al. method. It is far better than all other methods published. This paper solves one of the tremendous research tasks in cross science of chemical engineering and condensed matter physics.
