补充资料：分层的动态曲线
分层的动态曲线
kinetic curve of stratification
feneeng de dongtoi qux旧n分层的动态曲线(kinetie curve of stratifiea-tion)用于表述重选过程中底层重矿物的回收率随时间而变化的图形。由颗粒分层转移的概率统计关系得知，单位时间内进入底层的重矿物量与上部混合层中存留的重矿物量成正比。据此可写出重矿物回收率。随时间t变化的分层动态关系式: d￡ 夭二=K(1一￡) dt式中K为比例系数。上式积分后得 ￡=1一e一K，根据该式绘出的分层动态曲线如图，图中。，为某瞬时t重矿物在下层的回收率。____…上… -一，一 -厂 重选分层的动态曲线 (孙玉波)
