The minimal relative retention α’ and the required relative retention α’min of the pair of substances being most difficult to separate in a multicomponent mixture have been discussed on the basis of the fundametal retention equation ln k’=b0+b1CB+b2.n CB and resolution criterion. The selection principle to optimize elution composition means that selected a value must be greater than α’min and that the capacity factor of last peak should be held to a minimum. A rapid method to select optimum elution composition has been established in which it is necessary to do a few experiments. An example for the 5 pairs of phenylthiohydantion amino acids （PTH-AA） using the ternary mobile phase of methanol, ether and hexane is also demonstrated in this paper. The results show that theoretical prediction is good in agreement with the experiments.

采用溶胶凝胶技术制备了掺杂纳米CeO2.的纳米玻璃。XRD分析表明 ,掺杂CeO2.纳米玻璃为无定形。SEM分析表明 ,掺杂纳米CeO2.纳米玻璃中掺杂的纳米粒子分布均匀 ,无团聚现象 ;玻璃各成分之间混合均匀 ;采用不同溶剂所制备的纳米玻璃的致密程度不同。热分析表明 ,掺杂纳米CeO2.的纳米玻璃在 68℃附近有 1个吸热峰 ,故在该温度时 ,应长期保温 ,使样品中溶剂充分挥发 ,当温度达到 5 0 0℃附近时 ,样品几乎不再失重 ,仅发生致密化。
