Vapor over a boiling liquid is condensed and flows back into the vessel to prevent its contents from boiling dry. 气体通过沸腾的液体被压缩然后流回防止它蒸干的容器。
In this connection, the intense boiling of a superheated liquid can lead to the formation on the liquid surface of a rapidly expanding two-phase flow layer. In the vessel the gas and liquid phase being squeezed there may emerge the first pressure peak. 其中过热液体的剧烈沸腾,在液体表面形成高速膨胀的两相流层,挤压容器内气相与液相,导致出现第一个压力峰;
