    在實際的管理實踐中，我國目前採用一些已有的國家標準或部頒標準及其它的一些行業標準來對水工建築物的建設進行約束，雖然這些標準從某些方面對水工建築物的建設作出了具體規定，但隨著時代的發展，其內容有很多已不適應現實要求，而且這些標準政出多門，所涉及到水工建築物建造標準的內容比較分散，沒有形成一個完整的體系。
  2. Optimal periodic control with the lowest operational cost by limiting total substrate discharge mass was studied. through adding new state variable and using supplement functions, the problem with restriction conditions was converted into nonrestriction problem. in addition, the dynamic searching method of optimal step coefficient was developed to modify the conventional gradient method, consequently the calculation problem of the multivariable optimal periodic control was able to be resolved better. it was found that the operational costs of optimal control under various initial states are distinctly different. a new concept of optimal control under optimal initial state was presented. it is pointed out emphatically that to the treatment system without optimal control condition, the suboptimal control with extensive practical value can be realized according to the results of optima control

    著重研究了在限制有機物排放總量時，使其運行費用最低的最優周期控制問題.通過增加新的狀態變量和用補償函數法，將本課題的有約束條件問題化為無約束條件問題，並提出了最優步長參數的動態搜索法來修改傳統的梯度法，從而較完善地解決了多變量最優周期控制的計算問題.研究中還發現了不同初始條件下最優控制所需要的運行費用也大不相同，進而提出了最優初始狀態下最優周期控制的新概念，這對保證出水質量的同時進一步降低污水處理成本來說具有更重要的意義.本文還強調指出：對于尚不具備實現最優控制條件的處理系統，可根據最優控制的研究結果實現具有廣泛實用價值的準最優控制
  3. The main work of this paper was as fellows : ( 1 ) generalized the development of pre - stressed steel structure in our nation and abroad, and pointed out the main problem in practice ; ( 2 ) presented the mechanism of pre - stressed steel structure and revealed its applicable range ; ( 3 ) established the optimization design model for pre - stressed steel structure, which accounts for constraints on stresses and displacements of structure ; ( 4 ) brought forward the optimization design method, which combined linear programming and the principle of full restriction, through which we can obtain the magnitude of each time pre - stress and the optimized sections of each members of structure ; ( 5 ) analyzed the best times of pre - stress and pointed out that 2 ~ 3 times is preferable ; ( 6 ) conducted optimization design on large - space steel roof, horizontal parallel steel truss with local cables, horizontal parallel steel truss with global cable, and ultra - static steel truss, the result of which indicated that the multiple pre - stress structure is very economic ; ( 7 ) compared different schemes of cable placement for horizontal parallel steel truss, and the results showed that the local cable only unloaded the second girders, but had no response on the first girders and stomach poles, while global cable could unload the second girders and the stomach poles outside of turning point of cable, thus proving that global cable is more economic than local - cable

    本文的主要工作是：對國內外預應力鋼結構的發展歷史及現狀作了綜述和總結，指出當前預應力鋼結構工程實踐中存在的主要問題；闡述了預應力鋼結構的受力機理，並指出預應力鋼結構的適用范圍和特點；在考慮結構應力和變位約束的條件下，建立預應力鋼結構優化設計模型；提出多次預應力鋼結構優化設計方法和步驟，採用線性規劃和滿約束準則相結合的優化方法，可優化設計出施加的每一級預應力的大小，並得到結構各部分的優化截面；對多次預應力最佳的施加次數作了分析，並建議以2 3次為宜；為驗證文中理論和方法，分別對大跨多次預應力鋼屋架、局部布索的水平平行弦鋼桁架、整體布索的水平平行弦鋼桁架和局部布索的超靜定鋼桁架等算例進行了優化設計，經濟效益明顯；對水平平行弦鋼桁架的幾種施加預應力的方案進行比較，對于局部布索，預應力只對下弦起到卸載作用，對上弦和腹桿基本不起作用；而整體布索預應力除對下弦卸載外，對索折點以外部分腹桿也起到卸載作用，經濟效益好於局部布索。
  4. The dissertation accounts for that the basic reason that the accounting policy choice characterized of opportunism is the native defect of the contractual theory. another important factor is that the inside and outside mechanism of restriction of accounting policy choice is out of balance

    筆者認為，契約理論下的會計政策選擇之所以具有機會主義特徵與契約理論自身的缺陷有關，同時會計政策選擇內外約束機制的失衡及其會計質量水準不高也是重要的因素。
  5. Generally, structure ' s stresses, not internal force, can be obtained by analyzing discrete structures with routine solid elements, but internal forces of structure such as moment, axial force and shear force are required in the design criterions which are working in the design of hydraulic structures and industrial and civil structures. a convenient method based on the equilibrium condition of internal force and element ' s stresses is presented in this paper. this method can directly solve constraining internal forces on the designated sections, and then solve the moment, axial force and shear force on the corresponding sections

    一般情況下用常規的實體單元對結構進行離散后求解得到的是結構的應力而非內力，而現行水工結構及工業與民用建築結構設計規范的設計準則主要是建立在結構內力（如彎矩、軸力、剪力等）基礎上的，本文採用了一種根據單元應力及內力平衡條件直接求解指定截面上的約束內力，並進而求解相應截面上的彎矩、軸力、剪力等的方法，該方法不需要對應力進行擬合。
  6.
