Membrane affinity quantified by IAM and liposome/buffer systems was a more efficient predicator of α values than hydrophobicity from n-octanol/buffer system. Consequently, not only hydrophobic force but also attractive polar extra-interactions involved in the binding to IAM and liposomal membranes but not in an n-octanol phase, ascribed to the binding process within AM. The binding to ordered lipid membrane in the larger part determined drugs'binding to AM intracellular compositions, and the ordered phospholipid plasma membrane was a potential site for drugs'binding in AM.

The results indicated that both binary interactive parameters of water/isobutanol system from this work and the parameters of water/ethanol from literature can be used to precdict the liquid-liquid equilibria of water/ethanol/isobutanol. But the parameters of ethanol/isobutanol from the literature were not appropriate for the prediction. Furthermore, the model parameters from 30℃ can can be used to predict the liquid-liquid equilibria under 35 ℃. The model parameters of water/isobutanol are independent on the temperatures, so constant parameters irrelative to temperature can meet prediction accuracy. Othmer-Tobias/Bancroft equation was also used to fit the liquid-liquid data of water/ethanol/isobutanol system, but it didnt possess the performance of predicting the liquid-liquid equilibria.The partition coefficients of dipotassium glycyrrhizinat were determined in the liquid-liquid two-phase system of water/ethanol/isobutanol and corrected by experiential equation.

The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.
