摘要
视待碎物料为离散体(粉体),比照粘性流体研究方式,通过剪切试验,探讨随着离散体运动速度加快,其粘性系数(剪切力)将发生变化,进而研究离散体在不同的运动速度条件下,其剪切力的变化规律。
Compared with the method of study viscous fluid, crushed material is deemed to discrete body （powder）. With the increasing of discrete body movement speed, through the shear test methods, the viscosity coefficient （shear） of crushed material will change, the change law of shear stress was studied that the discrete body under the condition of different velocity.
