可以做练习来检验一下的，实际上很简单，假定有围绕x轴一起旋转的流体。

An exercise that you can do, which is actually pretty easy to check, is say that we have a fluid that is just rotating about the X-axis uniformly.

就其流变性而言，聚合物溶液和碱—表面活性剂—聚合物（ASP）复合体系均属粘弹性流体，但在中等剪切速率的简单剪切流动条件下，其流变性可用幂律模式描述。

The compound of Alkali Surfactant Polymer (ASP) is a kind of viscoelastic fluid, its rheological behavior can be formulated by power law model in simple shear flow within medium shear rate.

六通阀和DIV的同步协调运行使得建立一个简单的样品流路和连续流体经过分离柱的系统成为可能。

Synchronized movements of the six-way valve and DIV made it possible to establish a simple flow path of the sample and a continuous liquid flow through the column.
