利用Shuanglin Chen模型及马中庭计算式对Zn-Mn-Me和Zn-Ti-Me两系列三元合金镀液的组元活度及活度相互作用系数进行了计算。结果表明，Me为Ni和Cu时，均使呈色元素Mn或Ti的活度提高，Ni的影响程度比Cu显著得多，而Me为Ti和Mn时，Ti降低了Mn的活度，而Mn则提高了Ti的活度。通过与实验结果比较表明，镀液中溶质组元的活度与呈色效果之间有着必然的联系，即，凡是可以提高呈色元素活度的添加元素均有利于镀液综合性能的提高，从而最终优化呈色效果。因此，Mn、Ni和Cu均为彩镀液的有利元素，Ti的利弊与添加的相对量有关。
The activities and activity interaction parameters of two kinds of ternary alloy baths, Zn-Mn-Me and Zn-Ti-Me, were calculated by use of Shuanglin Chen model and Zhongting Ma expression. The results indicate that the activity of color generation element Mn or Ti increased as addition of Ni or Cu, where the effect of Ni is superior to Cu, however, the addition of Ti decreased the activity of Mn in Zn-Mn bath, and the opposite behavior for Mn in Zn-Ti. There is an inevitable relationship between the activity of components and color generation effectiveness. That is to say, the additives which can increase the activities of color generation elements would be in favor of improving the combination properties of hot-dip bath, and finally of color generation effectiveness. Therefore, Mn, Ni, and Cu are favorable elements for coloring hot-dip bath, and the advantages and disadvantages of Ti are related with its concentration, which is consistent with the results of technology experiments.
