补充资料：垂向分层理论
垂向分层理论
stratification theory of grains in vertical direction
ehuix旧ng feneeng Iilun垂向分层理论(stratifieation theory of grainsin vertieal direetion)对重选过程中矿粒群在介质中作垂向分层运动机理的阐释。在重选设备内堆置或铺置的动态矿粒群称作床层。借助介质的垂直流动、沿斜面流动或作回转运动使床层松散，是粒群发生分层转移的先决条件。分层是指矿物粒群按密度差形成不同的矿物层;颗粒的粒度以及形状对分层也有重要影响。对于分层的发生机理，曾经有过多种见解，但归纳起来不外两类观点。一类是动力学分层学说，认为分层是按个别颗粒在介质中的运动差异发生的(见自由沉降速度差分层学说、干涉沉降速度差分层学说);另一类是静力学分层学说，认为分层是粒群整体的内在不平衡因素引发的(见悬浮体密度差分层学说、位能分层学说和重介质分层学说)。前一类学说强调了流体动力对颗粒运动的影响，而忽略了颗粒间的静力作用;后一类学说的立论观点则忽视了流体动力对分层的影响，而将床层内颗粒或颗粒群间的静力差异视为分层的决定性因素。 (孙玉波)
