The thermodynamic properties, microscopic functions, and diffusivity of liquid Zn-Cd alloys have been predicted by the molecular interaction volume model (MIVM). These properties were also predicted by the self-association model (SAM) (O. E. Awe et al., Appl Phys A. 2017;123:363). Considered the deviation between the predicted values and the experimental values, the MIVM is more reliable and convenient than the SAM. Different from the results of SAM, the asymmetry of properties against concentration calculated by MIVM shows a relatively large reduction, which agreed with the experimental results. Moreover, some cross-over phenomena, which occurred in the conclusions analysed by SAM, were not found in the results from MIVM. The results of this study serve as a supplement to the thermodynamic description of the Zn-Cd system.

通过分子相互作用体积模型（MIVM）可以预测液态Zn-Cd合金的热力学性质，微观功能和扩散系数。这些性质也通过自缔合模型（SAM）进行了预测（OE Awe等人（Appl Phys A.2017; 123：363）。考虑到预测值和实验值之间的偏差，MIVM比SAM更可靠，更方便。与SAM的结果不同，MIVM计算得到的浓度对性质的不对称性降低幅度较大，与实验结果吻合。而且，在SAM分析的结论中发生的一些交叉现象在MIVM的结果中未发现。这项研究的结果可作为Zn-Cd系统热力学描述的补充。
