摘要
文章计算了废清液蒸发过程中液相组成及密度，在证实计算方法可靠的情况下，对青岛碱厂废清液蒸发过程进行了预测，给出了预测结果，同时计算补充了２０℃Ｎａ＋，Ｃａ∥Ｃｌ－－Ｈ２Ｏ体系的相图数据及等密度线，举例说明了等密度线的应用。
The concentration and density of waste clear liquid in the evaporation process is calculated.After the calculation method is proved to be reliable,the evapo-ration process of the waste clear liquid from Qingdao Soda-making factory is predicted and the results are given.At the same time,the calculation data of the phase diagam and isodensity lines is Na +,Ca ∥Cl --H 2O system at 20℃ is supplied.An example is cited to show the application of isodensity lines.
