摘　　要：本文研制了γ射线床层密度在线探测器,实现了跳汰机床层内沿垂直方向上三点处的床层密度测量,在此基础上,通过记录跳汰机床层密实期与松散期的密度值和脉动振幅,分析了密实期与松散期的密度差与床层松散度之间的关联关系,提出了用床层底层及上层同一点处的密度差构建床层松散度的二阶回归模型的方法。An on-line γ ray density detector was developed and the density values at three points in vertical direction of jig bed were obtained. By recording the density data in compact period and mobility period and the jigging amplitude of the jig bed, the correlative relation between the mobility and density differences in the compact period and the mobility period was analyzed. A mobility model was proposed, which establishes the quadratic regression model of mobility based on the density differences in compact period and mobility period.
