在渠道縱橫斷面優化方面，本文在利用已經比較成熟的縱橫斷面優化理論的基礎上，提出以工程總費用最小為目標函數，以渠道縱坡i為控制變量，以渠道不沖不淤流速及灌區允許地面比降為約束條件，通過縱橫斷面聯動優化的方法得到渠道的最佳工程可行的斷面參數。另外，針對部分地區的取土困難的狀況，本文採用積分法計算渠道工程土方量，從而大大提高了土方量的估算精度，有助於準確控制工程投資規模及資金投向。本文詳細闡述了該系統所採用的編程方法、系統構成、系統各組成模塊的開發過程以及灌區規劃所採用的優化方法及原理，最後應用本系統對泰州市翟家村機電灌區進行規劃設計，運行結果證明其操作比較簡便，界面友好，運行速度快，規劃成果合理，基本達到了系統預定的要求，具備較強的實用性。 -
As crude oil is extracted continuously in oil field, there are more and more low yield oil wells in old oil field, and the problem of void pumping is becoming more serious. rational control of the pump ' s work and rest time can save electricity, prevent the break of beam hanger caused by beating liquid, and reduce attrition of the pump
隨著油田原油的不斷開采，老油田的低產井越來越多，油井空抽現象也越來越嚴重，合理地控制抽油機的開機時間與停機時間長度，可以達到節電、防止擊液引起的油桿斷裂以及抽油機磨損減少的目的。 -
Three chefs work exclusively on the process, in which each step is essential : pumping up the ducks with air, soaking them with spices, coating them with honey glaze, blow - drying them, hanging them in the oven the result is a plump, crispy - skinned, juicy duck, which, after some skilled carving work by a chef, is ready for serving in the traditional way dipped in brown sauce and wrapped in a pancake with a section of spring onion
北平烤鴨是天廚的精神所在，三位師傅每天都忙於鴨子的吹氣腌漬上色風乾掛爐等瑣碎卻缺一不可的程序，烤出金黃飽滿皮酥肉嫩的鴨子，再經過師傅的巧手片成薄片，就可以沾著甜面醬與蔥段一起卷荷葉餅吃，汁多味美，日本餐飲雜志都經常介紹。 -
