Liquid-liquid heat exchangers with separation type vacuum phase transition have beenapplied to recover the low temperature heat in refinery for years.

数套工业装置已投用多年，其中中国石化抚顺石油化工公司石油二厂的真空相交换热工业装置每小时可为厂生活区供应１００～１３０ｔ洁净热水。

We investigate the phase transitions of Abelian lattice gauge theories at finite temperature with the variational cumulant expansion.

应用交分累积展开方法系统地研究了（２＋１）维和（３＋１）维的Ｚ（２）、Ｚ（３）、Ｕ（１）阿贝尔格点规范理论在有限温度下的相交。

The feasibility of this new operation was proved by the experiments in which two columns and three columns in periodic liquid material exchange were used as operation unit respectively and the system of ethanol-isopropanol(volume ratio of 1) ethylbenzene-para-xylene(volume ratio of 1) were chosen.
