So according to the technology regulation of reclamation engineering, hydraulic calculation must be carried out in the design of final closure. this paper firstly introduces the progression and present situation of reclamation engineering, emphasizing on the features of present reclamation and on the experiences and theories of home and abroad ; using fortran perfects the hydraulic calculation program of the closure and makes the program to meet different conditions ( such as considering flood, the variation of time interval, multi - entrance, multi - reservoir capacity ), and after comparing and analyzing a great deal of schemes, the reasonable computation scheme was brought up ; the interface of the program was carried out by the programming language vb to make the process of calculation become easier and more distinct, so the result can be analyzed and handled more directly ; vb is used in the later management of the result to plot the graphic chart of the isoline of the maximum of hydraulic element ( the velocity of flow, the drop height and the rate of flow ) automatically ; finally it was applied in the reclamation project of dongbidao of fuqing
本文首先介紹圍海工程的發展進程與國內外圍海的開發現狀，重點介紹了我國目前圍海工程的特點及在圍海工程實踐中積累的經驗和理論；利用fortran語言完善堵口工程龍口水力計算程序，使程序可以滿足圍海工程復雜工況下（如考慮內港洪水、計算時段的變化、多口門、多庫容、多水閘）的龍口水力計算，並進行大量方案的比較和分析，提出合理計算方案；利用面向對象的可視化編程語言vb進行界面開發，使計算過程有良好的人機界面，更直觀地對計算結果進行分析和處理；計算結果的后處理採用vb編程實現龍口水力要素最大值等值線圖的繪制；並運用所編軟體對福建省福清市東壁島圍墾工程進行龍口水力計算，為堵口合龍提供科學依據。Firstly the paper summarized the methods of passing over of neutral section and its application status quo in the domestic and oversea. as the research object of the paper, the reason of over - voltage caused by the method of ground transfer by vacuum breaker is analyzed though simulation and experiment. and based on the analyze, a method of automatic passing over of neutral section using thyristor vale to controlling the phase of electric power is presents
本文首先綜述了國內外自動過電分相的方式及應用研究現狀，並以地面開關轉換方式為本文的研究對象，通過模擬和實驗，分析了這種方式產生過電壓的機理，以此為基礎，提出了以晶閘管閥控制電網電源投入時刻的自動過分相方案。I see you can say nothing : in the first place, you are faint still, and have enough to do to draw your breath ; in the second place, you cannot yet accustom yourself to accuse and revile me, and besides, the flood - gates of tears are opened, and they would rush out if you spoke much ; and you have no desire to expostulate, to upbraid, to make a scene : you are thinking how to act - talking you consider is of no use
我看你無話可說，首先你身子依然虛弱，還得花好些工夫才能喘過氣來其次，你還不習慣于指控我，辱罵我此外眼淚的閘門大開著，要是你說得太多，淚水會奔涌而出，你沒有心思來勸說，來責備，來大鬧一場。你在思索著怎樣來行動你認為空談無濟於事。
