在298.15K下，测量了NaCl、KCl及其不同摩尔比下的混合物的水溶液的粘度及密度，浓度从很稀直至饱和、甚至过饱和．通过在现有的扩展Jones─Dole型方程中加入摩尔浓度的立方项，所得Jones─Dole型方程可在更高浓度范围内很好地表达所研究体系的粘度．随着浓度的提高，更高浓度次项需加入．用简单加和规则计算了混合物溶液的粘度，其结果与实验值在低浓度下相近，可解释为，有足够的水用来水化离子，离子间的作用对粘度几乎无影响；随着浓度的增加，计算值比实验值越来越小，因为离子间的作用越来越明显，并且各自的浓度由于彼此的存在和作用而提高．
At 298.15 K, the viscosity and density of the aqueous solutions of NaCl, KCl and their mixtures at different molar ratios were measured at very dilute to saturated and even supersaturated concentrations. By adding the cubic term of molarity to the existing extended Jones-Dole equation, the Jones-Dole-type equation can express the viscosity of the studied system in a higher concentration range. As the concentration increases, the next higher concentration need to be added. The viscosity of the mixture solution was calculated using the simple addition rule. The result is in agreement with the experimental value at low concentration. It can be explained that enough water is used to hydrate the ions and the interaction between the ions has almost no effect on the viscosity. With the concentration , The calculated value is smaller and smaller than the experimental value because the interaction between ions becomes more and more obvious and the respective concentration is increased due to the existence and action of each other.
