  1. This thesis takes the process of the futures delivery as the object of the research, analyzes and investigates the physical delivery system. firstly the thesis introduces the connotation, status and functions of the futures delivery in the futures market, and then makes a deep research in the futures delivery systems concerned such as the designing of the grade of the listed commodity at par as well as the premium and discount, the selection of the delivery locations and the regulation on the designated delivery warehouses, as well as the management and circulation of the warehouse receipts. on the basis of the above - mentioned analysis, this paper makes some constructive suggestions and recommendations on the improvement and innovation of the futures delivery to be taken by the chinese futures market at the present stage

    本文首先闡明了期貨交割在期貨市場中的經濟內涵、樞紐地位和功能保障作用；然後，從合約設計出發，用均衡原理揭示了期貨交割制度與品種活躍和風險控制的有機關系；進而，對比中外交割制度，通過比較，認清了中外現貨基礎、誠信和法制等環境因素的差距，明白了「拿來」的內容和如何構建中國特色的交割制度；從而，就小麥國家標準的歷史局限性，標準和替代交割品級及其升貼水的設計原則，交割標準把握的出發點和落腳點，交割倉庫設置和管理的目標和狀況，標準倉單沾滯的根源等期貨市場交割制度及相關規定，進行了深入而細致的剖析。
  2. 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。
