考虑柱压降对流动相线速的影响，建立起考虑柱压降的气液分配色谱质量平衡模型，在此基础上导出色谱流出曲线的一级、二级及三级中心距的表达式，并通过实验加以验证．
Considering the influence of column pressure drop on the linear velocity of mobile phase, a mass balance model of gas-liquid partition chromatogram considering the column pressure drop is established. Based on this, the expression of the first, second and third center distance of the chromatographic outflow curve is derived, And through experiments to verify.
