文摘:針對水石流顆粒粗，粘性小的特點，提出了利用水槽進行分段模擬水石流的設想，首次通過幾何變率解決難度較大的阻力相似問題，改變了以往過度加糙的方式;通過變粒徑比尺的方法消除了模型沙級配不連續相似的問題，較好地實現了固體物質級配相似，達到了泥石流的密度相似和輸沙相似.通過水槽概化模型試驗實例，對本方法進行了驗證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，用數據統計的方法，定量、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最大，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量，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斜政策，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優化和升級，五是加快城鎮化過程，優化農村產業結構。In this paper a numerical method for equations of transport and biodegradation in the fractured media is discussed. because the equations consist of terms related to advection, diffusion, biochemical as well as the term of exchange betwen the fracture and the porous media, it is very difficult to find their solution. in order to find more efficient method for solving these equations, several numerical methods for the equations without biochemical terms are discussed first. the numerical results show that the cubic spline method can be used to solve advection flow dominated problem which often occurred in the fractured media. then, the equation with both advection - diffusion term and biochemical term are discussed. the splitting - operator is used to decouple the advection and diffusion terms with biochemical term in the equations. the way to determine the smaller time step for solving fast biochemical terms is introduced through comparing the order of characteristic time of biochemical term with that advection ( diffusion ) term. numerical simulation results show that good agreement between analytical solution and experiment result is attained
本文討論了含裂隙介質地下水污染物輸運與生物降解非線性方程組數值求解方法.方程含有對流項、擴散項、生長、死亡、吸附、解吸、趨化和孔隙與裂隙介質界面間的交換項的非線性偶合，使演算法十分困難.本文討論了無生化過程時的幾種求解方法，數值結果表明：用三次迎風插值法對常見的對流項占優勢，且場變量有較大梯度的問題較適用.在討論有生化反應過程時，利用對流項與生化反應項的特徵時間量級估算，給出了求生化過程作用子步的時間步長估算辦法.用上述方法所得到的模擬結果與解析解、無化學反應和有化學反應的實測值對比，吻合很好分享友人
