secondary steam 中文意思是什麼
secondary steam
解釋
二次蒸氣-
Presents the steady - state programming with constant coolant average temperature and constant live steam pressure, an ideal programming for marine nuclear power plant ( npp ), under which, both the coolant average temperature and the live steam pressure of nuclear steam supply system ( nsss ) are constant when the steady state operating condition is varied, and points out that in comparison with the steadysate programming with constant coolant average temperature, the ideal programming can improve the overall operating performance of npp effectively, especially in low - load range, for instance, raise the heat efficiency of npp, decrease the operating noise of main coolant pump, and improve the conditions of design, operation and control of the secondary loop system
雙恆定運行方案是船用壓水堆核動力裝置的理想運行方案.在這種運行方案下，當裝置穩態功率變化時，冷卻劑平均溫度與蒸汽壓都保持不變，與通常採用的冷卻劑平均溫度恆定運行方案相比，有效地改善了核動力裝置的總體運行性能，特別是在低負荷運行時，可以提高裝置經濟性、降低主泵運行噪聲、改善二迴路系統的設計、運行和控制條件，這對于提高船用核動力裝置的運行可靠性和安全性具有實際意義 -
To the steam generator a heat exchanger, which converts the feed water in the secondary circuit to high - pressure steam at about 67 bar or 6 700 kpa and deliver it to the " conventional island " via steam pipe for driving the turbine and generator
內的高壓水帶到蒸汽發生器即熱交換器，蒸汽發生器會將二迴路給水轉化為約67巴或6 700千帕的高壓蒸汽，再經過蒸氣管送到常規島，以推動渦輪發電機。 -

The experiment took water as the medium and experiments on two jet modes were carried out under the falling film vacuum evaporating. the experimental results indicated that the two ejectors in series compensation method could adjust the variational work situation due to the decrease of primary steam or secondary steam and insure the normal production. at the same time, the ejector ' s best work situation founded in the experiment would provide reference for ejector ' s design and usage
本實驗建立了一套降膜真空蒸發裝置，以水為介質，對變工況下單級和串聯噴射熱泵蒸發進行了實驗，結果表明兩級串聯補償噴射裝置能對由引射蒸汽和工組蒸汽壓力降低所造成的混合蒸汽壓力降低進行調節，達到了變工況下正常生產的目的。 -
The water then passes through steam generators to deliver heat to the secondary circuit. the steam generator produces steam on the secondary side to drive the turbine and generator
產生的熱能，然後流入蒸汽發生器，通過熱交換，在二迴路產生蒸汽，以推動渦輪發電機，把熱能轉化為電力。 -
The break was assumed to be a single tube double - ended and three - tube double - ended shear break. the diameter of the break orifice is 0. 876mm and 1. 518mm respectively. the characteristic responses of main thermal - hydraulic parameters, such as primary pressure, secondary pressure, break flow rate, pressurizer level, secondary side level of steam generator and so on, were presented in this thesis
試驗再現了核電廠蒸汽發生器單根傳熱管雙端斷裂事故和三根傳熱管雙端斷裂事故發生后的熱工水力現象，給出了事故過程中一次系統壓力、二次系統壓力、破口流量、蒸汽發生器二次側水位、穩壓器水位、元件表面溫度等主要參數的瞬態響應。
