The whole thesis was made up of seven parts. the first part provided the background, significance and aims of this research ; the second part briefly reviewed the progress and the trend of the researches about the relative fields at home and abroad, then concluded that the present researches were mainly focusing on mineral cities and the qualitative description of mineral economics, which lack in quantitative analysis and utilized models ; the third part defined mineral region according to two indexes, and discussed the theoretical basis of the economic sustainable development of mineral region ; the fourth part systematically analyzed the current situation of the economic sustainable development of huangling county, emphatically discussed the coincidental relationship between mineral exploitation and economic development as well as the reasons for the recession of mineral economic ; the fifth part, drawing on the experience of transforming industry and renewing economic in mineral cities ( region ) at home and abroad, put forth the foundation train of thought of the economic sustainable development huangling county, and programs and smocks the economic development of huangling county using the method of systematic dynamics, presented the model of the economic sustainable development of counties by comparative analysis of three plans ; the sixth part provided some policed suggestion and measure for the economic susta inable development of huangling county

    全文分為七個部分:第一部分:提研究的背景、意義與目的;第二部分:簡要回顧了國內外相關領域的研究進展與趨勢,指當前研究主要集中在礦業城市與礦業經濟的定性描述,缺少定量分析和應用模型;第三部分:依據兩組指標定礦業區域,探討礦業區域經濟可持續發展的理論基礎;第四部分:對黃陵縣域經濟可持續發展現狀進行系統分析,重點探討了礦產資源開發與經濟發展的耦合關系及其礦業經濟衰退的原因;第五部分:在借鑒國內外礦業城市(地區)產業轉型與經濟新生經驗的基礎上,探討了黃陵縣域經濟可持續發展的基本思路,並用系統力學方法對黃陵縣域經濟發展進行規劃與模擬,通過三種方案的對比分析,提縣域經濟可持續發展模式;第六部分:黃陵縣域經濟可持續發展的政策建議與措施;第七部分:主要結論及進一步研究的問題。
  2. To completely avoid producing elements jointed at their corner nodes and checkerboard patterns, which frequently occur when the topology optimization of plane continuum is studied, the theory of topology analysis of plane continuum in topology optimization process and the simple algorithm for programming are studied. according to algebraic topology theory, the boundary of elements and plane continuum are operated as a one - dimensional complex. by use of the adjacency vector in graph theory, the structural topology is described and the topological operation is achieved on a computer. by above, the structural topological feature in the evolutionary process is gained. these methods are effcient and reliable. under topology constraints, according to the results of stress analysis, by deleting elements and moving nodes at the boundary, more satisfactory results can be gained by using a few numbers of elements and iterations. to demonstrate the efficiency of these methods, solutions including some well - known classical problems are presented

    避免目前平面連續體結構拓撲優化過程中經常現的單元鉸接以及「棋盤格」等現象,研究了連續體結構拓撲優化過程的拓撲分析方法,以及在計算機上實現的簡便演算法.根據代數拓撲理論,單元及連續體的邊作為1 -復形進行算.利用圖論中的鄰接向量概念,在計算機上實現了結構的拓撲描述及拓撲算,得到了結構在拓撲演化過程中的拓撲特性,方法簡單、可靠.在一定的拓撲約束下,根據應力分析結果,採用刪除單元、單元退化、移節點等方法,可以用較少單元得到更為滿意的結果,提高計算效率.為演示方法的有效性,給幾個包括常見經典問題的解答
