  5. Statistically, it makes a quantitive analysis on the evolvement of the country economic structure in xi ' an city, the economic benefit of the changes in industry structure, the effect on labor resource collacation in industry structure and the effect of the increasing income of countrymen in industry structure changes, which discloses a rule of the industry structure evolvement in country. the putting forward of the non - agriculture industry in country, especially the rapid increase in country industry will promote the rise of the country industry level for a long term. the country industry structure influences a lot the increase of the farmer ' s income which is also affected by agriculture structure and planting structure, but less. the non - agriculture industry plays a main role in the increase of farmer ' s income. for the low level of the townlization and industrialization, developing industry, construction and commercial in country is very feasible to resolve the problem of spare labors in country. it is strengthening labors transferring and reducing the modulus of labor over the infield that farmers income could be kept increasing. after a theoretical analysis and twenty years practise in the regulation of country economy structure after the reform and opening policy in xi ' an, a new thought of regulating country economy structure in xi ' an is put forward that a strategic regulation must be taken in country economy structure and the agriculture structure must be optimized. moreover, an expanding agriculture must be developed and transfer the spare labors in country effectively. so the government function during the regulation of country economy structure is transferred to : the first one, making the stress policy in the regulation of country industry structure. 2ndly, strengthening the force in regulating country industry structure ; 3rdly, making a plan on the regulation of country industry structure ; 4th promoting the optimizition and upgree of industry relying on sci - tech progress ; 5th enhancing the townlization and optimizing the country industry structure ; last one, improving the quality of labors in full scale

    本文在概述經濟結構理論的基礎上,第一次系統地研究了西安市農村經濟結構調整,用數據統計的方,定、定性地分析了西安市農村經濟結構演變的軌跡,分析了產業結構變動的經濟效益、產業結構勞動力資源配置效應、產業結構變動的農民收入增長效應,揭示了農村產業結構演變的規律。提出農村非農產業,尤其是高速增長的農村工業,對促進農村產業水平的提升起著長?推動力的作用;農民收入增長直接受農村產業結構的影響大,農業產業結構、種植業結構對農民收入有影響,但作用不可高估;非農產業是農民增收的主要支撐力,解決農村余勞動力在城鎮化、工業化水平不高的情況下,切實可行的選擇是在農村發展工業、建築業、商飲業等非農產業;農民收入要保持快速增長態勢必須加大農村勞動力轉移力度,減少耕地承載勞動力的系數。通過理論分析,結合西安市改革開放后20多年的農村產業結構調整的實踐,提出了西安市農村產業結構調整的發展思路及目標、原則,明確指出了政府在農村經濟結構調整過程中的職能轉變的重要方面:一是制定農村產業結構調整的傾政策,二是加大對農村產業調整的投入力度,三是制定產業結構調整的規劃,四是依靠科技進步促進產業化和升級,五是加快城鎮化過程,化農村產業結構。
  6. 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
