摘　　要：利用二维扩散模型，计算了连续环状萃取色谱床在不同操作条件下的流出曲线，并对不同操作条件、平衡常数、传质系数以及轴向和圆周向扩散系数对流出曲线的影响作了讨论．The concentration profiles at the outlet for different operating conditions have been calculated by using a two dimensional dispersion model of continuous annular extraction chronlatography. The effects of operating conditions, equilibrium constant, mass transfer coefficient and axial or annular dispersion on the type of concentration profiles at the outlet are discussed.
