The amount of time between sample mixing and viscosity assessment is critical, especially for non-Newtonian liquids.
在试样搅拌时和粘度测定之间的时间数量是很严格的，特别是对于非牛顿体的液体。

In some common textbooks or reference books concerning on polymer rheology, the concept of true viscosity of non-Newtonian fluid is explained unclear, and parts of the calculation results are wrong.
The viscosity is one of the most important flow properties of blood, the blood is a non-Newtonian fluid. the viscosity of blood is change with the shear rate changes.
