摘　　要：本文从微观分子相互作用的角度,考察了液固吸附色谱三元流动相方程lnk'=α+c_1C_B_1+c_2C_B_2+b_1lnC_B_1+b_2lnC_B_2中各系数的物理意义,研究了系数间的相互制约关系,同时提出了系数c_1、c_2的计算方法。In this paper, the parameters in the retention equation Ink' = a +c_1*C_(B_1)+ c_2 * C_(B_2) +b_1*ln C_(B_1) +b2 * lnCB2 in ternary solvent system in LSC weresystematically investigated in view of the molecularinteractions. b1 and b2 are displacement parameters and c1 and c2 stand for the interactions in the ternarysolvent. b1 and b2 play a significant role in parame-ters c's equations in LSC. We also propose amethod to calculate the parameters c1 and c2.
