In addition , this model can be generalized easily in the case that many units competing in an obturating system and only one or few will win finally 本模型可以無困難地推廣到多個個體在一個封閉系統中競爭,僅有極少數個體最終獲勝的情形,文章所得結果對于該類復雜系統的建模具有普適意義。
Now it is transport obturated , economic failed behind , transport manner singleness and programming lagged in chongqing ' s southeast district . these badly restict the area ' s economic development 目前渝東南地區交通閉塞,經濟落后,交通方式單一、規劃建設滯后,嚴重制約了區域經濟的發展。
Widely applicable to the various necessaries occasions for solid - liquid separation such as life municipal sewage , papermaking , textiles , dyeing and chemical effluent filtration , especially in the white water treratment of papermaking , it will achieved the obturating and recycling pupose 廣泛適用于需進行固液分離的各種場合,如城市生活污水、造紙、紡織、印染、化工污水等的過濾,尤其適用于造紙白水的處理,達到封閉循環重復使用的目的。
Due to some relative independence between departments in enterprise , and short of consolidated plan and standard when designing application systems , there must be some information islands in the application systems , which are separate , heterogenous , obturated and unshared 在企業內部,由于部門間相對獨立,構建系統時缺乏統一的規劃和標準,所以造成了現有的應用系統是分散、異構、封閉的系統,相互之間不能共享信息,形成了一個個“信息孤島” 。
We put forward an algorithm for self - discrimination of island relation and an automatic intersected method of the region machining unit , which can judge the relationship among any plane obturate contour line effectively and swiftly . we also study the tool path generation technology of two - dimensional machining , basso - relievo machining , three - dimensional lifting - pen machining . meanwhile , we put forward an optimize approach of tool path , which improve the efficiency of engraving 研究了圖像的刀具路徑生成技術與軌跡規劃問題,提出了基于射線的島嶼關系自動判斷和區域加工單元的自動分割方法,有效、快速地判斷了平面任意封閉輪廓線之間的關系,研究了平面任意區域填充加工、浮雕加工、三維提筆加工的刀具路徑生成的技術,提出了刀具路徑優化方法,提高了雕刻加工的質量和效率。
5 ) the 3 - d geometry and finite element model of the assembly of the optimized obturator of the breech mechanism is set up in terms of the optimized structural parameters . quasi - static and dynamic finite element analysis of stiffness , strength and obturating performance of the optimized obturator of the breech me chanism is performed 利用優化后的結構參數建立了優化后炮閂閉氣結構的裝配體三維幾何實體模型和有限元模型,對優化后的炮閂閉氣結構剛強度和閉氣性能進行了準靜態及動態多體接觸彈塑性有限元分析。
