Density, surface tension and rheological characteristics are the essential properties of the non-Newtonian fluid. Pycnometer, surface tensiometer, and rheometer were adopted respectively to measure the density, surface tension and rheological characteristics of 0.25%, 0.50%, 0.75% PAM aqueous solutions at 293.15K. The parameters of equations were fitted in terms of the experimental data.
密度、表面张力和流变性质是非牛顿流体的基本性质，本文采用比重瓶、表面张力仪和流变仪分别测定了293.15K温度下质量浓度依次为0.25%、0.50%和0.75%PAM水溶液的密度、表面张力和流变性质，并对数据进行了关联，拟合了方程参数。
-
Correlation e-quation between the pycnometric and densimetric determination of relative density was obtained by regression analysis of test data.
用这两种方法测得的结果一致与否，为探求这两者之间相关关系的密切程度和表现形式，通过测定系列香精的密度，并对所得数据进行线性相关和回归分析，得出了比重瓶法与密度仪法所得结果的相关方程。
