本論文通過物理試驗與理論分析對輸水管道系統中的氣體特性、壓力水流沖擊截留氣團和包含氣體釋放和液柱分離現象的含氣水錘進行了深入研究。The paper is on how to set up lab platform of vapour spewing to uppercooling water surface to coagulate directly and to observe and analyse which vapour coagulate on the water surface, the results enable people to know the security system of nuclear power. the range of the pressure parameters of prz is from 0. 2mpa to 0. 6mpa, and the range of the initial temperature parameters of cmt is from 23. 5 to 78. 5, all of the testing points are 30 and there are fifty thousand testing data. many results of vapour spewing to uppercooling water surface vertically to coagulate can get. for example : coagulating can make the water of cmt surge forcefully when vapour spews to uppercooling water surface, too many vapour - bubbles come into being and strike the water of cmt owing to rupture continually, all these will strengthen the surge because of the vapour pressure of cmt
實驗中prz飽和蒸汽壓力變化范圍為: 0 . 2mpa - 0 . 6mpa ， cmt中水初始溫度變化范圍: 23 . 5 - 78 . 5 ，實驗中測試工況30個左右，實驗測試數據50萬余個，得出了很多與非能動安全系統相關的蒸汽垂直噴向過冷水表面凝結時的結論：蒸汽垂直噴入過冷水表面凝結時會造成cmt中液面的強烈波動和振蕩，產生大量蒸汽汽泡，汽泡不斷破裂對cmt中液體帶來很大沖擊，勢必引起cmt中液體的振蕩，造成cmt汽空間汽壓不均勻，加強cmt液體的振蕩和波動。Sintering speed increased greatly with the help of great quantity of heat of the molten iron, the great quantity of heat sent out from the carbonizing reaction and a little quantity of liquid, this sintering type is an instantaneous sintering, the sintering compacting can carry completely in a few minutes, the degree of sintering compacting is very high.
