The traditional economy theories, such as the monetary theory of keynes, friedman and harrod - domar growth model, discussed the role of finance in economy growth from different aspects. in addition, the dispute between finance deepening theory and finance restrain theory is what government should do in the financial development. the theory of modern financial development studies how the financial structure works on the industrial structure by researching on the evolvement of financial institutions and financial markets
根據馬克思在《資本論》中的闡述，可以得出金融資源參與產業資本循環是社會化大生產的必然要求的結論;在傳統西方經濟學理論中，凱恩斯的貨幣經濟理論、弗里德曼的新貨幣數量說和哈羅德-多馬模型等理論分別從不同角度論述了金融在經濟增長中的作用;金融深化理論與金融約束理論之爭引導人們開始探索政府在金融發展中的作用問題，而當代金融發展理論則從金融機構與金融市場的形成機制角度，探討了金融結構對產業結構的影響。Secondly, the penalty coefficient may converge to infinity in many situations when the iterative point is closely near the bound of feasible set, while the parameters are bounded if the solution set of constrained optimization is nonempty, which is available for numerical computation
另外在很多情況下，罰函數法中的罰因子當迭代點接近可行域邊界時趨于無窮大，而參數控制演算法中，只要約束優化問題有最優解，則參數是有界的，這對數值計算是有利的。Based on modern optimization theory and optimal control theory, this dissertation studies some questions as follows : 1. the optimization model of parameter identification of three - dimensional geologic history numerical simulation, algorithm and its application geologic history numerical simulation is a basic content of basin numerical simulation, and the porosity is the major parameter in the evolution and development process of oil - bearing basin. according to the sedimentation and burial mechanism, the physical and chemical principles of oil geology, the mudstone porosity ' s non - linear parabolic partial differential equation has been established
本文應用現代最優化及最優控制理論，對如下一些問題進行了研究： 1 、三維地史數值模擬的參數辨識優化模型、演算法及應用地史模擬是盆地數值模擬的一個基礎性的研究內容，地層孔隙度是含油氣盆地地史演化發育過程中的重要參數，根據地層沉積埋藏機理和石油地質的物理化學原理，通過引入數學物理方程概念，建立了泥巖三維孔隙度場方程，根據問題的特點，給出了方程的定解條件，對方程的動邊界也給出了處理方法，並且證明了解的存在性與惟一性，在此基礎上建立了以當今實測數據為擬合準則的三維地史數值模擬的參數辨識優化模型，這是一個含有二階偏微分方程約束的泛函極值問題。According to the design theory of the cable - stayed bridge and to the feature of the cantilever construction the authors propose a construction control method called optimum completion state method ( ocsm ) for rc cable - stayed bridges in the proposed method, the optimum completion state is regarded as the final target of the construction control, and the optimum construction state at each construction stage is taken as the technical route the key of the method is to properly choose or adjust the cable forces the objectives function of optimization is to minimize the elevation error of the girder under the constraint condition that the internal forces ( bending moments ) of the girder are bounded the optimization variables are the cable forces on the basis of the above principles, a optimum model for a construction step is established and cable force adjustments can be found for each construction step in this model, the creep and shrinkage effects of concrete have been considered a bridge example is given which shows that the final state of the bridge is very close to the design aim and that this method is much better than the so - called double - control method the example is a good illustration of the soundness and practical value of the proposed method
根據現代斜拉橋結構設計理論和懸臂施工方法的特點，提出了以最佳成橋狀態作為施工控制的最終目標，以實施最佳施工階段為技術路線，以索力調整為核心內容的斜拉橋施工控制理論，簡稱為最佳成橋狀態法；以斜拉橋主梁標高誤差最小為目標函數，以主梁內力（彎矩）為約束條件，以索力為優化變量，建立了最佳施工階段的索力調整計算模型；推導了考慮徐變收縮效應的索力調整計算公式；用最佳成橋狀態法對一實橋工程進行了施工控制全過程計算研究，得到的成橋狀態與設計目標相當接近，優于該橋以「雙控」為控制目標的實測結果，有力地證明了本文方法的正確性及其工程實際價值Currently most works on pc employ the sensitivities of the stability energy margin to the generator power injections, which exist some disadvantages and the cause of potential divergence in computation are analyzed. the amount of pre - assigned harmful contingencies in large power systems is a real chanllenge for pc. in this thesis, it is settled soundly through grouping these contingencies into some subsets according to each unstable mode ( um ) provided by eeac, and identifying the worst contingency among each subset by stability energy margin provided also by eeac
預防控制研究大多基於控制參數相對于系統暫態穩定裕度的靈敏度系數，本文分析了此類方法存在的不足和可能迭代不收斂的原因；依據eeac的暫穩裕度量化指標和失穩模式概念，解決了起關鍵作用的暫穩約束的識別問題，克服了當前該領域中僅能研究小規模系統和或少量預想事故約束的局限。分享友人
