在层流条件下，剪切应力与剪切速率成线性关系时的斜率值。计量单位为“mPa.s”。用范氏粘度计测量时，600r/min的读值与300r/min读值之差即为塑性粘度。
同时，对直圆管内宾汉流体屈服应力和塑性粘度对湍流流动的影响进行了探讨。
We performed numericai computations of Bingham fluid turbulent flow in a straight circular pipe. The conclusions are as …
常温时压力对表观粘度和塑性粘度影响很大，但随着温度升高，压力的作用逐渐减小。
The effect of pressure on the apparent viscosity and plastic viscosity is considerable at ambient temperature. However, this effect is reduced gradually with the increase in temperature.
随着塑性粘度的增加，宾汉流体和颗粒相的主流速度分布出现了与屈服应力带来的影响的相反趋势。
With the increasing of the yield stress, the velocities of Binghamand particle decrease, but with the increasing of the plastic viscosity, the velocities of Binghamand particle increase.
