Both the and DtV$ for the glycyl dipeptides increase with increasing molality of sodium acetate. The interactions between charged center or glycyl units of the peptide and ions dominate those between alkyl groups of the peptide and the ions. The interaction between the peptides and sodium acetate is mainly pairwise. The results were interpreted successfully by the cosphere overlap model.

果皮、果肉中的丙二醛质量摩尔浓度前期上升，后期下降，但峰值出现的时间和前期增幅都不同，自交琯溪蜜柚的峰值来得早，增幅也大。

The osmotic coefficients and saturated vapor pressures have been calculated at the different temperatures .The experimental values of the osmotic coefficients for the Li_2SO_4-H_2O system were consistent with the values in the references. The results revealed the rules of the changing in osmotic coefficients and saturated vapor pressures with ion strengths and the molality fractions of Li_2B_4O_7 at different temperatures. The isopiestic equilibrium molalities were correlated by using the modified and the extended Zdanovskii rules for non-ideal mixtures, and obey well the Zdanovskii rules. The ion interaction parameters of Pitzer model have been determined by using the two methods for Li_2SO_4-Li_2B_4O_7-H_2O at 298.15K system.
