Approaching the parameters of distillation operation through phase law and diagrams, the relation of vapour-liquidequilibrium shows directly.
综合相图、相律及相平衡关系，分析精溜操作中的状态参数，使抽象的相平衡内容具体、直观。
2
A concise physical picture is furnished by chemical potential curve about the law of phase equilibrium, saturated vapour pressure of curved liquid surface, evaporation and condensation etc.
通过曲线描述，提供了关于相平衡、弯曲液面饱和蒸气压以及蒸发、凝结等规律比较直观的物理图像。

Next, the physical properties and vapourliquidequilibrium data must BE collected, and finally the type of absorBEr is chosen and designed.
