为了检查简单密度方程和粘性方程的适用性在里面，到非电解质答案，密度和粘性的半理想答案理论在 298.15K 为第四级的系统 mannitol-sorbitol-D-glucose-H2O 和它的第三的分系统 mannitol-D-glucose-H2O 和 sorbitol-D-glucose-H2O 被测量。结果被用来为密度和粘性测试简单方程的适用性多部件非电解质答案。在预言并且测量的结果之间的协议好。

英文摘要：

To check the applicabilities of the simple density equation and viscosity equation in the semi-ideal solution theory to nonelectrolyte solutions, the densities and viscosities were measured for the quaternary system mannitol-sorbitol-D-glucose-HzO and its ternary subsystems mannitol-D-glucose-H2O and sorbitol-D-glucose-H2O at 298.15K. The results were used to test the applicability of the simple equations for the density and viscosity of the multicomponent nonelectrolyte solution. The agreements between the predicted and measured results are good.
