This machine is comprised of screen box , vibration source and damper , vibrating frame and screen box are connected with 4 - 12 group soft rubber damp - ers fixed up and down , and the centrifugal force is generated therein , the floating ampli - tude is controlled by the damper , by which , material realizes a process of throw and lami - nation filtration downward , and therefore reach - ing the optimized grading and screening ef - fect 本机由筛箱.振动源及减震器三大部分组成.振动机架与筛箱连接有4 - 12组软橡胶减震器上下固定,产生离心力,由震器控制浮动振幅,使物料有一个向下抛震和向下分层过滤的过程,从而达到最佳分级过筛的效果

In the simulation of friction reduction on a flat plate , since the effects , including the order of magni tude of several interact ions between water and microbubbles and correlated coefficient models of interactions , on the results are unknown , which are rather important in establishing the simplified model put into the theory and engineering practice , the results about them are presented as the preparation for the further study 在平板微气泡减阻中，由于水-微气泡之间的各种相互作用力的量级，以及这些作用力的系数模型对计算结果的影响是未知的，而这一点在建立简化模型开将期应用于理论和工程实践中是相当重要的，因此本文对此进行了计算，以为深入研究作准备。
