本文採用瑞斯納中厚板理論求解彈性地基板，建立雙參數地基與中厚板相互作用的控制微分方程，結合胡海昌的解耦函數，運用雙五次b樣條函數作為試函數的離散型最小二乘加權殘值法分析了雙參數地基上的中厚板的彎曲問題，並將結果與有限元線法、有限條法、級數精確解等進行比較，證明本文方法具有足夠的精確性與實際的可行性。The main contributions of this dissertation are listed as the followings : l ) deducing and proving the " three in one " theory of natural monopoly, that is, from the angles of economies of scale, economies of scope and economies of network, giving an explanation of natural monopoly ; 2 ) putting forward the concept of " strict superadditivity " and proving that total value function and total revenue function of network economy have strict superadditivity ; 3 ) summarizing the emerging characteristics in the market definition of natural monopoly, that is, in the monopoly industry, " market " tends to be more and more smaller than " industry " ; 4 ) expounding that the objective patterns of regulatory reforms of the railway industry in china are explicit regulation with partly characteristics of implicit regulation ; 5 ) proving the idea that the structural reforms of the railway industry in china should be hierarchical ; 6 ) demonstrating the theoretical bases for whether infrastructure management should be separated from transpo rt operation ; 7 ) expounding and proving that the interior of the railway industry in china should implement the differential property rights reform pattern
本文的研究特點在於： （ 1 ）在規模經濟、范圍經濟的基礎上進一步推導並證明了網路經濟與自然壟斷的關系，即自然壟斷可以從規模經濟、范圍經濟、網路經濟三個角度來解釋論述； （ 2 ）明確提出了一個與鮑莫爾、潘澤與威利格等人提出的「成本劣加性」相類似的概念? ?價值優加性，並證明了網路經濟的總價值函數和總收益函數具有嚴格優加性； （ 3 ）概括了自然壟斷市場界定中所出現的新特徵，即在壟斷產業中， 「市場」正越來越小於「產業」 ； （ 4 ）進一步論證了中國鐵路產業規制創新的目標模式是兼有部分內生規制特點的外生規制； （ 5 ）在中國鐵路產業的結構改革中應體現分層次的思想； （ 6 ）明確論述了內容提要鐵路路網公司等自然壟斷環節是否分割的理論基礎; （ 7 ）提出並進一步證明了中國鐵路產業內部應實行差異化的產權改革模式。A part can be located rapidly in a huge assembly tree by its attribute information, thus the part can be edited in design context. at last, author develops a set of tool with ug / open application programming interfaces and menu tools. using the tool, visible parts in a view can be selected automatically and invisible parts can be blanked or closed automatically according to user ' s requirement
快速操縱大裝配，利用組件過濾器和控制開關快速打開大裝配，減少大裝配的打開時間；利用組件的屬性信息操縱大裝配樹，快速定位查找裝配體中某一組件以便在裝配的上下文中編輯組件，修改組件的設計；最後利用ug的介面函數和菜單定義工具二次開發實現了大裝配體在某一視圖中可見組件的自動選取，自動隱藏或關閉不可見組件，減少了內存中加載組件的數量，能在某一視圖中快速操縱大裝配。First the thesis elaborate the basis principles of land sustainable use, according to the natural and social economy situation, the characteristics of the land use, the aids and the principle of evaluation, we work out an index system form four aspects of productivity, protection, viability, acceptability. the weigh of indexes are defined by means of analytic hierarchy process, the standardization of indexes are defined by effective function, then, we use multi - aid decision model which mainly reflects that indictors influence on aim and multi - aid liner function which mainly reflects aim the degree of land sustainable use during 1996 and 1999 in taigu
論文從土地資源可持續利用的基本理論入手，結合太谷縣的自然、社會經濟狀況與土地利用的特點，依據評價的目標和原則，從生產性、資源保護性、經濟可行性、社會可接受性四個方面，採用專家咨詢法建立了太谷縣土地資源可持續利用評價指標體系，採用層次分析法確定了指標權重，應用功效函數法進行評價指標的標準化處理，運用反映評價指標因子對評價目標的影響程度的多目標突變決策模型和反映評價目標的可持續利用程度的多目標線性加權相結合的方法，對太谷縣1996年到1999年的土地利用情況進行了評價。This article gets some good results on the two - order markov chains on the base of the studies of one - order markov chains : in infinite experiment, the frequency of times of stationary state is accessing to transition probability. the indication function which is the times of appearance is a special function, so this paper in forth chapter continue to study more general function regarding to two - order markov chains, which is the property of the function of two - order markov chains. in chapter five, this paper study the convergence of cesaro averages for two - order morkov chains
