一、前言液体粘度和分子运动之间的关系十分复杂,至今还没有通用的理论,也没有一种满意的方式将液体粘度与其它物质特性相联系。因而,虽然有许多液休粘度的计算式,如:Tho-mas法,O-E法,Morris法,V-C-L法,E-D法,Antoine方程,Souder法和Andrade法等,但这些计算式有的限于一定的液体种类,有的限于狭窄的温限,有的虽应用范围广,但精确度还需要提高。因此,设法整理一个通用的且精度较高的液体粘度计算式,是一项有待继续的工作。 I. INTRODUCTION The relationship between liquid viscosity and molecular motion is very complex. There is no general theory so far and no satisfactory way to relate liquid viscosity to other material properties. Thus, although there are many formulas for calculation of liquid viscosity, such as the Tho-mas method, OE method, Morris method, VCL method, ED method, Antoine equation, Souder method and Andrade method, Liquid species, some limited to a narrow temperature limit, while others have a wide range of applications, but the accuracy also needs to be improved. Therefore, trying to collate a common and high accuracy liquid viscosity formula, is a work to be continued.
