| 6. | This paper analyzes the factors to influence the information entropy and establishes the information entropy change model via economic data 根据同期的社会经济数据,分析了影响信息熵变化的因素,并建立信息熵变化模型。 |
| 7. | Among three kinds of extractant , the entropy of tbdooda extraction is biggest , that of tbopda is least . lt means that configuration entropy makes the greatest contribution to the whole entropy change of extraction 只有tbopda适宜于从hllw中问收分离钢系和澜系元素,对三价崩谰苹取分配比高。选择的稀释剂为40煤油辛醇。 |
| 8. | But the population genetic that based on the statistic model ca n ' t explain the entropy change disciplinarian in the process of evolution , and the genetic diversity index system not enough prefect 但目前建立在统计学基础上的群体遗传学尚未阐述清楚进化过程群体的熵变规律,而且遗传多态性分析的指标体系不够完善,因而必须用信息论方法科学描述和丰富遗传多样性的指标体系。 |
| 9. | By using theories from the relevant disciplines such as geography , mathematics , physics , ecology , and system sciences , this thesis develops a framework employing the concept of system entropy to represent the state function of the man - earth relationship system . in this framework the entropy change is used to show the development change of the system , and the entropy flow to express the flow among the spatial parts of the system . following the framework , and based on a large set of household data from surveys , the thesis makes a quantitative analysis of the village - level man - earth relationship system from a micro - perspective 借助地理学、数学、物理学、生态学、系统科学等有关学科理论,根据实地调查的大量农户数据,从微观视角对村域人地关系系统进行了定量分析,用人地关系系统熵来表征人地关系系统的状态函数,用熵变来反映人地关系系统的发展变化,用熵流来表示人地关系系统各空间型式地域主体之间的流动。 |
| 10. | 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,分子生物技术的介入及核苷酸序列进化的研究都为群体遗传学的深入研究提供了新的途径,但关于dna序列数据的分析方法需要作进一步的研究。本研究主要体现在以下几个方面: (一)关于群体遗传学的信息论模型研究,主要分为三部分内容:一是群体平衡的shannon信息熵的性质和群体平衡建立的熵变性质;二是群体遗传多样性测度的研究;三是非平衡群体的基因变异测量shannon信息量的方法研究。得到了如下结论: 1 、平衡群体的shannon信息熵最大,群体平衡的过程是熵的增大过程。 |
