在dcs側，通過組態的方法，在不增加新測點的前提下實現了汽包集中下降管管孔處主應力的在線計算；在mis側，採用基於數據庫的客戶機/服務器結構，服務器端程序對從dcs系統來的數據進行初步的處理並存儲在oracle數據庫中，客戶機端程序完成數據的最終處理及結果的顯示 -
Sgk - b250 plastic pipe belling machine attribute semiautomatic opportunities for the single - use. such models use infrared heating, molding method adopts expand the headers to finalize the design, orifice size precise shape. the control panel don ' t have the conversion switch to control over the type of solvent for expansion socket ( vertical ) and ring - for flexibility expansion socket ( r ). expanding way is very easy choice and technics adaptability is strong, the main electrical control components are imported, system performance is stable and reliable
B250塑料硬管擴口機，屬半自動型作單機使用，擴管時管材由人工搬至擴管工位：這種機型採用紅外線加熱方式：成型方式均採用擴管頭定型方式，管口成型尺寸準確：該機型在控制面板上沒有擴溶劑型承插口（直口）和擴彈性密封圈型承插口（ r口）的轉換開關，擴管方式選擇十分方便，工藝適應性強：主要的電器控制元件均採用進口元件，系統性能穩定可靠。 -
The research indicates that the orifice jet in mixing conditions has many different points from the pipe jet. focusing on the jet ejected from the orifices of different diameters and lengths, this paper studies the orifice jet when the fluid upstream of the orifices is in mixing conditions. the main purpose is to qualitatively study the effect of orifice diameters and lengths on the spread of the jet
射流是在工程實際中廣泛存在的一種流動現象，噴嘴出口的流動狀態對射流的發展有很大的影響，前人對射流的研究主要集中於噴嘴前流體是完全發展管流的情形，本文研究了全混狀態下的板式射流，研究結果表明全混狀態下的板式射流具有很多不同於管射流的特點。 -
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。
