initial surge 中文意思是什麼
initial surge
解釋
初生涌浪-
The dam protected height is determined as 15m higher above reservoir water level during initial reservoir impounding period in order to preventing surge damage caused by landslide
李家峽水電站壩前號滑坡屬有蠕滑活動的老滑坡，體積為1845 104m ~ ，為預防滑坡涌浪危害，初期蓄水期間壩前設防高度15m 。 -
Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly - varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, in hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed
若這些海上建築物的上部結構底高程較低，在惡劣海況下當大波浪在其面板下面通過並與之接觸時，面板下面除了作用有強度變化較緩慢的波壓力外，在波峰剛接觸到面板時尚存在著歷時很短但強度極大的沖擊壓力，這種極強沖擊荷載會引起建築物的整個上部結構失穩或造成局部破壞。 -
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。
