该清洗机利用淬火油等挥发性液体减压后沸点下降，和油、水、水蒸气等一起加热，其沸点亦下降的原理进行清洗。
The principle of the vacuum washing technology is based on the boiling point of volatile liquid like quenching oil will decrease by decompression and by heating with water and other organic liquid.
我们来画相图，蒸汽压下降，意味着凝固点降低，和沸点降低。
And we also drew a phase diagram to show how this vapor pressure lowering was going to imply freezing point depression and boiling point depression.
长期使用也能维持较高的沸点而其安全性较高，很少由于吸湿而出现功能下降。
It is safe for maintaining high boiling point for a long time without deterioration of quality from moisture absorption.
