在小、中、大口径连续柱逆流色谱仪上测定了15种两相溶剂体系在不同流速(F-c)下的固定相(S-F)保留率。 S-F回归分析表明，流量的平方根与固定相保留百分比之间呈线性关系，即S-F=A-B根F-C，其中A表示溶剂体系中溶剂组成的差异，B表示相同组成的溶剂体系中溶剂体积比的差异。 (C) 1999 年由 Elsevier Science B.V. 出版。保留所有权利。
The retention percentages of the stationary phase (S-F) at various flow-rates (F-c) of 15 two-phase solvent systems were determined in three types of counter-current chromatographic apparatus equipped with small-, middle- and large-bore coiled columns. The regression analysis of S-F showed a linear relationship between the square root of the flow-rate and the retention percentage of the stationary phase, i.e. S-F=A-B root F-C where A indicates the difference in the solvent composition of the solvent system and B indicates the difference in the volume ratio of the solvents for the same composition of the solvent system.
