A computer-assisted method is presented for simultaneous optimization of pH and ion con-centration selection for the optimal separation in reversed-phase HPLC.The method is based on apolynomial estimation from nine preliminary experiments according to two-factor rectangular design.This is followed by a two-dimension computer scanning technique.Resolution is used as the selectioncriterion.Good agreement was obtained between predicted data and experimental results.

研究了一种8090Al-Li合金中平衡相T2(Al6CuLi3)和δ(AlLi)数量变化对合金室温力学性能的影响。结果表明,合金经过双级时效(210-300℃,4h+回复处理+160℃,100h)后,T2相的大量析出会使合金的强度有所降低,塑性有一定程度升高,而δ相的大
