摘要
二元牛顿液体的粘度系数与一元牛顿液体粘度系数相似.与激活能和温度的关系可用指数形式表示。对二元牛顿液体而言.激活能与其中一种液体浓度有关.本文导出了这一函数关系.对含水甘油进行了讨论。计算了0℃到40℃各种浓度甘油溶液的粘度系数.并与实验数据进行比较.结果表明.在一定温区内.理论值与实验值基本一致.
The coefficient of a binary solution, like that of a single liquid, can be expressed as an exponential function of activation energy and temperature. For a binary liquid, the activation energy is related to the concentration of one component. The relation is derived and applied to water-containing glycerine. The coefficients of the glycerine solution of various concentration at temperatures from 0℃ to 40℃, are calculated and compared with experiments, it turns out that within a certain range of temperature, the theory is approximately consistent with experimental results.
