The equilibriumphasediagram and the density-composition diagram of the quaternary system were plotted using experimental data.
依据实验测定的平衡溶解度数据及对应的平衡固相，绘制了该四元体系的平衡相图及其密度-组成图。

A specific enthalpy method associated with the alloy equilibriumphasediagram is employed to account for the latent heat of phase change.
对于潜热处理，采用了基于合金平衡相图的比热焓法；
3
The local phaseequilibrium principle is recommended as well as the outline of the method of diffusion couples in determining the equilibriumphasediagram.
