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(wú)困難地推廣到多個(gè)個(gè)體在一個(gè)封閉系統(tǒng)中競(jìng)爭(zhēng),僅有極少數(shù)個(gè)體最終獲勝的情形,文章所得結(jié)果對(duì)于該類(lèi)復(fù)雜系統(tǒng)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(qū)交通閉塞,經(jīng)濟(jì)落后,交通方式單一、規(guī)劃建設(shè)滯后,嚴(yán)重制約了區(qū)域經(jīng)濟(jì)的發(fā)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(jìn)行固液分離的各種場(chǎng)合,如城市生活污水、造紙、紡織、印染、化工污水等的過(guò)濾,尤其適用于造紙白水的處理,達(dá)到封閉循環(huán)重復(fù)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(yè)內(nèi)部,由于部門(mén)間相對(duì)獨(dú)立,構(gòu)建系統(tǒng)時(shí)缺乏統(tǒng)一的規(guī)劃和標(biāo)準(zhǔn),所以造成了現(xiàn)有的應(yīng)用系統(tǒng)是分散、異構(gòu)、封閉的系統(tǒng),相互之間不能共享信息,形成了一個(gè)個(gè)“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(shù)與軌跡規(guī)劃問(wèn)題,提出了基于射線的島嶼關(guān)系自動(dòng)判斷和區(qū)域加工單元的自動(dòng)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(guān)系,研究了平面任意區(qū)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(shù),提出了刀具路徑優(yōu)化方法,提高了雕刻加工的質(zhì)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(yōu)化后的結(jié)構(gòu)參數(shù)建立了優(yōu)化后炮閂閉氣結(jié)構(gòu)的裝配體三維幾何實(shí)體模型和有限元模型,對(duì)優(yōu)化后的炮閂閉氣結(jié)構(gòu)剛強(qiáng)度和閉氣性能進(jìn)行了準(zhǔn)靜態(tài)及動(dòng)態(tài)多體接觸彈塑性有限元分析。
