One problem, as the producers of the rocky series know only too well, is that sequels are subject to the laws of diminishing returns
這個問題就連《洛奇》系列電影的製片人也一樣熟悉,那就是這些結局都會受到收益遞減規律的制約。At present, liaohe oilfield is in its middle and late stages of exploration and development, which means it is more difficult to keep a stable production. in recent years, a series of stimulation measures such as reperforation, water plugging and so on have been taken in different parts of the field to improve oil production and relax the natural depletion
目前,油田勘探和開發均已進入中、後期,穩產難度越來越大,為了阻止原油產量的遞減,近幾年遼河油田在全油區都不同程度地加大了進攻性措施的工作量,對油井採用了補層、堵水等一系列技術措施,大大的提高了油井的產量,有效的緩解了全油田產量的自然遞減。Especially, when the isocline of x is monotone decreasing in 0 < x < 1, the svstem has no limit cycle and is globally stable ; next, we construct a saddle bifurcation at the boundary equilibrium and a degenerated bogdanov - takens bifurcation at the interior equilibrium by choosing appropriate parameter values in the following two sections, where our work are based on the theory of central manifolds and normal torms. we prove that is a codimention 3 focus - type equilibrium. system ( 6. 1 ) will have two limit cycles at some appropriate bifurcation parameter values, and have homoclinic or double - homoclinic orbits at some other appropriate bifurcation parameter values ; at last, we study the qualitative properties of the system at infinite in the poincare sphere
因為系統在( 0 , 0 )點處沒有定義,這給研究其在( 0 , 0 )附近的動力學性質帶來了困難,我們應用文獻[ 17 ]中關于研究非線性方程奇點的系列理論和方法,圓滿解決了這一問題,給出了第一象限內當t +或t -時,在全參數狀態下系統的軌線趨于( 0 , 0 )點的所有可能情況,其相圖也得以描繪;並且,系統不存在極限環的幾個充分條件我們也予以列出,當x的等傾線在0 x 1范圍內遞減時,系統不存在極限環,全局漸近穩定;然後,我們以中心流形定理和正規型方法為主要工具,巧妙選擇參數,分別構造了一個余維2的鞍點分岔和一個余維3退化bogdanov - takens分岔,證明了平衡點是余維3的焦點型平衡點,存在參數, m ,的值使得系統( 6 . 1 )有兩個極限環,還存在參數, m ,的另外值使得系統( 6 . 1 )有同宿軌或雙同宿軌。Xf series parallel shaft helical gear units have the feature of small volume, light weight, heavy transmission torque, steady startup, low consumption, various mounting types and flexible in input and output etc.
Xf系列平行軸斜輪減速機具有體積小重量輕傳遞扭矩大起動平穩低損耗安裝方式多樣,輸入輸出靈活等特點。At the same time j2ee platform technologies are discussed deeply, such as j2ee platform technologies, communication technologies, ejb component technologies and so on. the design model based on the mvc frame is applied in the system development, so that the separation between the present logic and the business logic in the application is realized. finally, according to the problems found in the development process, the paper explains particularly the kay technologies in the realization : the uniform naming service is realized by realizing the service locator partten using the value object pattern, all the status data is encapsulated into a serializable object, then transferred among the client, sessionbean and entitybean in order to decrease the potential network traffic caused by reference of entitybean ; in order to improve the performance of data storing and taking, we introduce the facade model to escapsulate the ejbs which delegate the data model
本論文結合了杭州市財政局的會計人員從業資格管理系統的升級項目,研究了基於j2ee的ejb組件模型的多層分散式體系結構的設計與實現:深入探討了三種分散式處理技術( rmi , corba , com )的區別,將j2ee平臺的ejb技術與windowsdna體系的com +技術從多個角度進行了比較;詳細闡述了在系統開發過程中j2ee平臺的幾項核心技術(如: j2ee平臺的服務技術、通信技術、 ejb組件技術等)的應用;引入了源於mvc三部件框架的設計模式,實現了應用中表現邏輯與業務邏輯的分離;最後,結合在開發過程中遇到的問題,詳細解釋了開發過程中實現的關鍵點:用servicelocator模式實現了統一的命名服務管理;運用valueobject模式將所有狀態數據包裝成一個可序列化對象vo ,然後在客戶機、 sessionbean與entitybean之間傳遞,減少了使用實體bean造成的潛在網路通信量;以及引入sessionfacade模式,用sessionbean封裝了entitybean ,改善了數據存取的性能。We find that the transitivity of limit of a sequence of fuzzy relations is preserved if the involved t - norm and t - conorm are continuous. also some ideal results are obtained when the sequence is monotonic and the involved t - norm and t - conorm are left continuous t - norm and right continuous t - conorm respectively. in addition, some results are still available without continuity
我們指出:對連續的;模及t余模,若模糊關系序列具有某種傳遞性性質,則其極限具有同類性質;對左右連續的,模及『余模,在序列單增或單減時得到一些較為理想的結果;在沒有任何連續性的前提下,單增序列的s負傳遞性可保證其極限的s負傳遞性,單減序列的t傳遞性可保證其極限的t傳遞性。分享友人
