Abstract : in this paper, an analytical study of the dynamics of the piston in a reciprocating internal combustion engine is conducted. the equations of reynolds and moving of piston are derived. a useful method of solution is obtained. the method is applied to s1100 diesel engine. the results of this study indicate that piston oil film is found to be sensitive to the piston - cylinder bore clearance, the location of the wrist pin and lubricant viscosity
文摘:對往復式內燃機活塞的動力特性進行了分析研究，導出了活塞潤滑的雷諾方程和活塞運動方程，給出了可供實用的求解方法，並採用這種計算方法對s1100柴油機進行了設計計算與試驗研究.研究結果表明，活塞潤滑油膜歷程與活塞& &缸套的間隙、活塞銷的位置、潤滑油的粘度等因素密切相關 -
Multi - bore and lateral wells can improve the oil recovery efficiency, increase productivity and reduce cost. the reasonability and perfection of drilling engineering design are the key and precondition to drill lateral wells. the principles &, methods of type selection, optimum design of well trajectory, selection of sidetrack ways, design of drill strings &, drilling fluid and completion design are introduced in this paper
從生產實際工作出發，論述了現行鉆井井史標準在貫徹實施中存在的問題，提出了應增加及改進修訂的一些項目內容，如填寫要求、鉆具、鉆頭、定向井及井控技術等，對井史標準的修訂及鉆井工藝技術信息資料的採集錄入存儲和利用，有一定的參考價值。 -
According to the theory of developing viscous crude with screw pump and combined with the reservoir characteristic and oil property, fault block 70 is developed reasonably and effectively through a series of corollary technique including chemical pre - processing in the formation, viscosity decrease in the well bore, down - hole anchoring of screw pump, optimized design of screw pump, reasonable determination of the turning rate of screw pump, frequency alternating control, heat exchange and viscosity decrease in well head, monitoring of screw pump
依據螺桿泵開采重油的理論，結合澤70斷塊稠油油藏的特點和原油物性，通過實施地層化學預處理、井筒降粘、螺桿泵井下錨定、螺桿泵優化設計、螺桿泵合理轉速的確定、變頻控制、井口換熱降粘、螺桿泵監測等一系列螺桿泵配套工藝技術，使澤70斷塊得以合理有效的開發。 -
Even a small bit of mud, snow, excess lubricating oil or grease in the bore can cause dangerously increased pressures, causing the barrel to bulge or even burst on firing, which can cause injury to the shooter and bystanders
即使極少量的泥沙、雪、過量的潤滑油或油脂都可能導致膛內壓力危險地升高，進而造成槍管鼓脹甚至炸裂，而這會嚴重傷害射手和旁觀的人。
