  1. 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。
  2. This paper describes the basic features and components of data warehouse system, and deals how to use description - driven technology to integrate different data warehouse systems, how to implement the change from one data schema to another, how to clean dirty data in data transformation process, and how to exchange data among different components or systems. at last, this paper takes two products to illustrate how to implement systems following these principles and methods. these two products are the e - chain system as an application in commerce domain, and the ftedws system as an application in engineer test domain
