摘要
The entropy increase (EI) and the entropy increase per unit time (EIPUT) of the solute zone are chosen as new criteria of separation efficiency in chromatography and electrophoresis. It is verified by grand canonical ensemble (GCE) that the kinetic energy distribution of the solute is a common characteristic of the entropy and the distribution of solute zones.Under the assumptions. EI of the solute system is directly proportional to the logarithm of the difference between one and one half of the substantial separation ratio. the ratio of moles of a sparated solute to its total moles. and EIPUT is direchy proportional to corrected separation rate of separation system. EI or EIPUT is a important bridge between separation efficiency of chromatography or electrophoresis and operating parameters, especially. when nonequilibriumthermodynamics(NET) would be adopted.
利用熵和熵增率作为色谱和电泳分离效率的新判据，并通过巨正则统计分布方法证明了溶质的动能分布可以表征溶质区域分布和熵增的共同特性．在所假定的条件下，分析得出，熵增率正比于分离系统的校正分离比．墒增或熵增率构筑起一个表征色谱或电泳分离效率和可操作参数之间关系的桥梁．
