根系伸展
英文
root extension-
The mesoproterozoic mafic dyke swarms are extensively distributed in the central north china craton, which are not deformed and metamorphic, emplacing the pre - existed fractures, so the dyke swarms become the conspicuous marks to reconstruct the mesoproterozoic tectonic stress field of the central ncc. the mafic dykes in the northern block are transtensional while the dykes in the central and southern blocks are extensional. the mesoproterozoic tectonic stress field could be simulated on the analysis of the distribution and mechanical origin of the mesoproterozoic mafic dyke swarms in the central ncc. the simulation result shows that the mafic dyke swarms were formed in the extensional tectonic setting in the ncc in the mesoproterozoic time, which are related to the extension of the mesoproterozoic yanliao - zhongtiao aulacogens cross the central ncc
克拉通北部地塊的鎂鐵質巖墻群為張剪性，而中部和南部地塊為張性。根據華北克拉通中部中元古代鎂鐵質巖墻群的分佈和成因機制分析，來恢復模擬中元古代的構造應力場。數值模擬結果表明鎂鐵質巖墻群在中元古代形成於伸展的大地構造背景，與橫穿華北克拉通中部的燕遼-中條拗拉槽系的伸展作用有一定的聯系。The paper can be divided into four chapters : the first chapter introduced the background for app to carry on green marketing. in the first part, it expounded the theoretical basis for green marketing, including the emergence of green marketing concept, the details, characteristics and necessity for enterprises to develop green marketing ; in the second part, it presented the development background of app and its contribution in introducing green papermaking into china ; in the third part, it elaborated the strategic significance of green marketing for app, i. e. not only meeting the demand of enterprises ’ long - term development but also the demand of social development ; in the fourth part, it discussed the choice of app to invest in market and analyzed china ’ s market structure, raw material structure, development bottleneck and market opportunity of top - level paper
再次，根據金光紙業的實際情況及綠色營銷的相關理論指導，對金光紙業開展綠色營銷提出了相關建議，包括:綠色產品研發、清潔生產、綠色產品推廣、綠色品牌的實施計劃等一套完整的綠色紙業計劃;通過產品線全面策略、專業化策略、延伸策略等進行綠色紙業產品組合策略實施並按照管理學上的「 5r 」操作原則實行全面管理和渠道管理;通過對各綠色營銷子系統的協調控制，以期達到綠色營銷整體績效最優;最後對金光紙業各品牌進行全面整合，使品牌資源累計共享，提高在市場上的競爭力。If the technicians applied technology in the wrong, even achieving the business logic, but probably leading to many vices including low performance, low scalability, close coupling, low software duplication. so how to assemble the j2ee technology reasonable and achieve a system with high performance and high expansibility is my research emphasis in the thesis. in order to solve the problems and implement efficient web application, the paper put forward ejs _ mvc model according mvc pattern and we can assemble component by using ejs _ mvc model, it can solve many problems of web application and improving system with clear flow and clear function partition, in addition, due to controller is the most importance in the ejs _ mvc model, so the thesis also discuss some problems about controller design ; if the model is not designed accurately, system performance will encounter fatal influence, so the article lucubrate ejb technology from ejb choice, ejb optimized design, database access, design pattern etc and bring forward some strategies and methods about how to build efficient business tier ; finally based on ejs _ mvc model, a example that contains simple business logic is developed according to the object - orient software engineering thinking and some strategies and methods proposed by the thesis, in the process of achieving system function, the emphasis is probing into how t o assemble and apply technology reasonable and providing a new thinking thread and method contributing to build high effective and flexible j2ee application
由於j2eeweb應用是由組件組成，因此為了解決上述問題，實現高效的應用，本文首先從如何合理組合組件入手，找到一種方法使各組件能具體分工而又緊密合作，在深入研究各組件基礎上，根據mvc模提出了ejs _ mvc模型概念，指出可按此模型組合各層組件，該模型可以解決傳統web開發中存在的問題，而且具有系統流程與系統功能劃分清晰，可擴展性、可維護性強等優點，另外由於控制器是ejsmvc模型的重中之重，它起到承上啟下的作用，它設計好壞直接關繫到整個應用的性能、伸縮性與擴展性，因此又探討了控制器設計的有關問題；另外如果模型設計不當的話，對系統性能造成的影響可能是致命的，因此本文又從ejb組件選擇、 ejb調優設計、數據庫訪問和設計模式等方面對ejb技術作了全面的分析研究，指出在業務層中如何避免太多網路遠程調用和提高業務層性能，特別是根據前面的分析總結出了業務層的優化分層組合模型，這個模型的使用無疑會使業務層具有較高的性能與伸縮性；最後選擇一個業務邏輯較簡單的系統，使注意力集中到運用的j2ee技術上來，按照ejs _ mvc模型與軟體工程流程以及本論文所提出的方法與策略實現業務邏輯，在實現過程中具體探討如何合理運用組合技術，就多層j2ee體系結構的設計思想作深入的探討實踐，為實現高效、靈活的多層j2ee應用提供一種新的思路及方法。Steel frame with welding joint easily occur brittle collapse because of having a low ductility at joints then ， a semi - rigid connected steel frame has large the energy absorption capacity which can resist dynamic loads and the using steel qualities of bracing system and joints are small so adopting a semi - rigid jointed steel frame is economical and stable but for semi - rigid connections are complex and variable ， in conventional analysis and design of steel structures ， it is usually assumed that the connections between columns and beams are either rigid or pinned the analysis of steel frames adopting the assumption can simplify the procedure of analysis and design ， but cannot precisely reflect structural practical circumstance and the errors of calculating results are large ， even ， get incorrect conclusions semi - rigid connection was referred to in chinese code for design of steel structures ( 2001 ， 10 ) ， however ， it isn ’ t specified how to apply semi - rigid joints in design in fact it cannot be carry out the purpose of the paper give a calculating method that accords practical engineering and easily put into effect worthwhile it is going to promote the development of semi - rigid jointed steel frame in design and heighten structural stability in the paper ， at first some commonly employed methods for the modeling of connection behavior are introduced richard abbott function modeling of connection is adopted for extended end plate bolted connection by the 34 test data comparing to regression analysis indicate richard - abbott function modeling of connection represents an excellent fit to test data then after a semi - rigid joint behavior can be modeled as a finite stiffness rotation spring ， base on rotation and displacement equation derive the element stiffness matrixes with semi - rigid connections where the effects ofj ointed flexibility geometric non - linearity and shear forces in the connection deformations have been considered in and fixed - end forces are modified finally, a program for calculating semi - rigid with incremental - iterative method has been
本文的目的就是為半剛性連接鋼框架的設計提供一種既符合工程實際又簡便易行的計算方法，供規范使用過程的補充、延伸或參考；同時，也將促進半剛性連接鋼框架設計技術的發展，為提高結構安全性能、節省工程成本發揮應有的作用。本文首先介紹了常見的幾種應用較為廣泛的樑柱連接彎矩轉角關系模型，在分析比較的基礎上，選用richard ? abbott函數模型作為外伸端板連接彎矩轉角關系模型，通過對34個外伸端板連接的實驗數據與回歸分析得到的參數比較可知，經回歸分析得到的此模型參數與實驗數據符合較好。然後用彈簧表徵連接點的轉動剛度，根據梁的轉角位移方程推導出半剛性連接的剛度矩陣，在單元剛度矩陣中考慮了節點柔性、幾何非線性和剪切變形的影響，並對固端力進行了修正，最後用增量迭代法編制有限元程序進行計算和分析。分享友人
