So must use information theory method depict and abundant the genetic diversity index system. in addition to, the introduce of molecule biology technology and the research of nucleotide sequence evolutive give a new method for population genetic, so must do deeply research about the analysis method of dna sequence data = the research main about the follows : there are three parts about the information model of population genetic : one about the shannon information entropy property of equilibrium population and the entropy change in the process of establish equilibrium ; another research is about the diversity measure - ment of genetic variation ; lastly, research the shannon information measurement about the disequilibrium gene variation. the result is : 1 to a definite gene distribution, the genotype entropy reach the maximum at the equilibrium population, the process of population from disequilibrium to equilibrium, the entropy get large and large
此外，分子生物技術的介入及核苷酸序列進化的研究都為群體遺傳學的深入研究提供了新的途徑，但關于dna序列數據的分析方法需要作進一步的研究。本研究主要體現在以下幾個方面： （一）關于群體遺傳學的信息論模型研究，主要分為三部分內容：一是群體平衡的shannon信息熵的性質和群體平衡建立的熵變性質；二是群體遺傳多樣性測度的研究；三是非平衡群體的基因變異測量shannon信息量的方法研究。得到了如下結論： 1 、平衡群體的shannon信息熵最大，群體平衡的過程是熵的增大過程。 -
The variation of the film composition can be monitored by using the method of spectrum analysis during the film deposition ( for the intensity of the persistent line is proportional to the particle density of the element in the vacuum chamber ). the measurement of the transmission spectrum of the film on a transparent substrate can be used to calculate the film parameters, such as refractive index, extinction coefficient and the thickness of the film. therefore, the combination of the two methods would be helpful to on line monitoring the film constituents and the optical paramenters in the preparation of thin films
在制備薄膜的過程中，利用光譜分析的方法，以放電光譜特徵譜線強度的變化來反映相應物質成分的變化，以連續光譜光源發出的光透射過薄膜的透射率的變化，來反映薄膜的厚度、折射率、吸收系數等光學參數的變化，從而達到在制膜過程中，對薄膜的成分、厚度等參數進行在線監控的目的 -
The monte - carlo method is applied to analyze the reliability of soil nail stability and to discuss the averages and variation coefficient of soil parameters on the reliability index based on an engineering example
研究各種參數的重要程度以及影響范圍，得出有意義的結論，並對土釘設計施工提出建議和要求。 -
In order to study the relationship between homogeneity and performance variation of asphalt mixture, based on digital image processing technology, using the regression method, the relationship between homogeneity of asphalt mixture and air void, dynamic stability and mechanical strength of asphalt mixture was quantitatively investigated via the index of homogeneity of asphalt mixture
摘要為了研究瀝青混合料均勻性與性能間的相互關系，基於數字圖像處理技術，通過瀝青混合料均勻性指標，利用回歸方法對瀝青混合料均勻性與空隙率、動穩定度及力學強度間的相互關系進行了定量研究。 -
This paper assesses and analyses disaster degree of flood - waterlogging disaster by use of three - factor influence assessment method. it establishes the synthetic disaster index model and analyzes the in fluence degree of different disaster factors on synthetic disaster condition by use of the method of continuous substitution. the study results show as follows. the variation of disaster degree has the features of quasi - period and of development by stages ; the factors of flood disaster condition are the main influence factors on variation of synthetic disaster condition ; the influence direction of different factors are not all the same, and the factors that enlarge disaster condition show the new characteristics of flood - waterlogging disaster ; because the waterlogging disaster is serious da ybyday, the control of waterlogging must be strengthened
運用三因子聯立評估法，評定了洞庭湖區洪災，澇災和洪澇災的災度，進行了相應的分析;構建了洪澇災情指數，並運用聯環替代法對各災情因素的影響進行了分析.分析得出:洞庭湖區洪澇災度具有階段性和準周期性等特徵;洪災災情因素是綜合災情變化的主導影響因素;各災情因素影響方向不完全一致，其中起放大作用的因素反映出洪澇災害的新特點;澇災日趨嚴重，應加強澇災治理
