摘　　要：分析了国际科技界著名的气体粘度方程的基本不足和缺陷后,应用有机分子的半金属结构理论中的两个定理,以气体粘度的微观机理为基础,提出无机与有机纯质的通用型的气体粘度理论方程,经用极性与非极性包括量子气体在内的32种结构类型128种纯质520个实测值检验,平均误差仅1．20％,其精度比REID,PRAUSNITZ院士推荐的著名公式(CHUNG,LUCAS和REICHEN- BERG等的公式)高2．0-3．5倍,极显著地优于文献中各式。After the analytical defects of gas viscosity equations known in international technological science, a general theoretical equation of gas viscosity for inorganic and organic pure substances is proposed by using the 2 theorems in semi - metal structural model of organic molecules and based on micro - mechanism of gas viscosity. This equation can be applied to both nonpolar and polar gases including quantum gas, with an average error of about 1.2% from 520 experimental values, 128 pure substances of 32 structure types. Its accuracy is 2.0 - 3.5 times higher than that of Chung method, Lucas method and Reichenberg method, recommended by Reid et al. It is far better than all other published methods. From relating micro - mechanism of gas viscosity, physical regularity is presented for interacting forces of micro - particles in gas. A mathematical analytical form of relative values among micro - particles forces is proposed based on the theory of argon model. There is no the fact in the scientific developing history. One draw lesson from it to research other respects in future. It is considered to be an important creation.
