本文说明了处于斯托克流态、含有若干互不影响的球体的切变流内,加入另一球体时,所引起的扰动场具有如下的性质:在任何与流速变化方向垂直的平面上,切力总和为零。这种平面上的扰动速度,其值为一常数,平面位于球心一侧的数值为正时,则在另一侧其值为负。由此可知,所有球体不会使切应力发生变化,仅能使切应力减小1-2.5C,C为悬液浓度。本文最后建议:C不很小时,爱因斯坦公式可改为:η=η_0/(1-2.5c) This paper shows that in the Stokes flow state, a shear flow containing several spheres that do not affect each other, the disturbance field caused by adding another sphere has the following properties: on any plane perpendicular to the direction of the flow velocity variation, The total shear force is zero. The perturbation velocity in this plane is a constant value, and when the value of the plane on the side of the center of the sphere is positive, the value is negative on the other side. It can be seen that all the spheroids will not change the shear stress, only to reduce the shear stress 1-2.5C, C for the suspension concentration. Finally, we suggest: when C is not very small, the Einstein formula can be changed to: η = η_0 / (1-2.5c)
