In escherichia coli, arog gene encodes phenylalanine - sensitive 3 - deoxy - d - arabino - heptulosonate - 7 - phosphate synthase isoenzyme arog that catalyzes the first committed step of shikimate pathway. here we study the essential amino acid residues involved in the formation of feedback inhibition site of arog, and the effects of n - terminus on feedback inhibition and its quaternary structure, and the importance of the structural " d2 " symmetry to allosteric inhibition

    本博士論文工作以大腸桿菌k - 12來源的arog為研究對象，通過定點突變、反饋抑制實驗和酶學動力學參數的測定，深入地研究了arog的反饋抑制位點的特性，並對arog的n -末端在反饋抑制機理和維持穩定四級結構中的作用，以及蛋白質結構的「 d2 」對稱性對酶功能的重要性等進行了具體的研究。
  4. This paper includes a number of contributions on how to harmonize the macro and micro, global and local, random and structural, order and disorder, simple and complex, and so on, which is the significant task for the complexity exploration. it is research course that is more important than others, but still several conclusions have been drawn as follows : regional speciality lies in spatial complexity, the process of spatial complication starts from symmetry rebuilding in macro - level while symmetry breaking in micro - level which accounts for emergence of complex regularity, and the target of geographical evolution seems to reconstruct the symmetry laws of nature

    標度律是全文的邏輯核心，通過它們將城市系統的宏觀與微觀、整體與局部、有序與無序、隨機與確定、簡單與復雜、對稱與對稱破缺等對立問題有機地統一起來。盡管如此，本文還是得出了一些基本結論:所謂地理學的區域獨特性實則空間復雜性，微觀層面的對稱破壞與宏觀層面的對稱重組是「突現」和空間復雜化的動力根源，城市系統自組織演化的優化目標似乎就是重建大自然的對稱律。
  5. At the same time, according to the excellent capability of ip curves, we study fitting and description of objects, determination of invariants of objects, symmetry detection and recognition of objects based on ip curves. in all, the main contributions in the dissertation are as follows : ( 1 ) a method of determining automatically the scale of the multiscale edge detection is proposed based on the variant distance of the variogram function, and a method of segmenting texture images is also presented. the variograin values are taken as stochastic and structural properties of texture images and variant distance is taken as the size of image window

    同時，基於隱含多項式曲線良好的物體描述與識別能力，對物體邊界輪廓的擬合、描述、不變量特徵的提取、識別以及物體對稱性檢測作了系統的研究，主要成果及創新之處有： （ 1 ）基於變差函數的變程，提出了圖像多尺度邊緣檢測中尺度大小的自動確定方法；將變差函數的變差值作為紋理的統計和結構特徵，依據變程確定窗口大小，給出一種新的紋理圖像的分割方法。
  6. The study of the statement and extant problems in china analyzes that although china possesses a unique and rich culture resources, the people has a low awareness of the protection of the culture resources ; the distribution of the culture resources lacks competition at the international level ; the irrational distribution of the culture resources restricts the development of the culture resources. based on the above - mentioned achievements, the paper states the categories of china ' s culture markets and its consumption groups. after illustrating the statement of the market capacity of china ' s culture industry by a model, the author points out that in spite of the fast development of china ' s culture markets, the course of its development, which moves along a horizon of low level balance between supply and demand, is in a state of non - symmetry and has structural conflictions

    根據以上研究成果，本論文得出了以下基本結論：我國的文化消費由於收入水平的不同，不同的消費群體之間有著很大的差別，且區域間的文化消費不平衡，出現了由東向西的「擠壓傳遞放應」 ；我國文化產業的市場空間沒目前雖然發展很快，而且有著巨大的發展空間，但是在其發展過程中是一種低水平總體上的供求平衡，處于非對稱狀態，存在著結構性矛盾；我國居民在文教娛樂服務消費擴大的同時，其內部結構並不完全合理，這其中的消費，絕大部分是教育消費，而教育支出的過于龐大，實際上已經制約了居民的其它文化消費。
