In this study, on the basis of information theory and statistical methods, we use mutual information, n-tuple entropy and conditional entropy, combining with biological characteristics, to analyze the long range correlation and short range correlation in human Y chromosome palindromes.

本文中，我们利用信息论和统计学的方法并结合生物学的特征研究人类Y染色体回文序列的互信息、'n字'熵、条件熵，定量分析了回文序列的长程关联和短程关联，发现其中既存在长程关联，也存在短程关联，并且它们主要是由序列中的重复序列引起的。

In this paper the thymus DNA of calf and the pBs plasmid are the main objects of our studies in ultraweak luminescence. By means of PIAS(Photon-counting image acquisition), ultraweak luminescence detector and Lambda Bio 40 of UV/VIS spectrophotometer, we studied the UL of DNA induced by the three oxygen free radicals: singlet oxygen Oa, hydroxy radical and superoxide anion(O2 ). We found that the OH can greatly increase the UL intensity of DNA.

本论文以小牛胸腺DNA和质粒pBs为实验材料，利用光子图像探测系统(Photon-counting image acquistion，PIAS)、微弱发光测量仪和UV／VIS分光光度计和生物统计学的成组比较法原理对单线态氧(~1O_2)、羟自由基、超氧阴离子(O_2~-)三种氧自由基诱导DNA超弱发光的变化过程进行了研究，结果发现这三种氧自由基中·OH能诱导DNA的超弱发光发生显著的增强变化，而其他两种氧自由基对DNA的超弱发光并无显著诱导作用。

The thesis introduces the basic thoughts and contents of the robust statistics first, then applied the robust statistical methods to the analyzing of the residents' income and expenditure data of Tianjin City on this foundation, and then makes contrast with the traditional statistical methods, thus embodies the advantage of the robust statistical methods sensitively when the actual data doesn't obey the theoretical assumptions.

本文首先介绍稳健统计学的基本思想及其内容，在此基础上还将运用稳健统计方法对天津市居民收入和支出数据进行系统而全面的实证分析，并与传统的统计方法进行对比，从而从感性的角度来体现稳健统计方法在实际数据并不服从理论假定时所具有的不可比拟的优势。

In this paper,two nonlinear anisotropic diffusion filtering methods are presented and they are based on the multispectral anisotropic diffusion models proposed by Pope and Acton.We build a couple of new diffusion coefficients in partial derivative equation based on Tukey's biweight estimator error norm by recurring to the relationship between robust statistics and anisotropic diffusion incorporated with the nonlinear time-dependent cooling technique for gradient threshold.

在Pope和Acton提出的两个多光谱图像各向异性扩散滤波模型的基础上，通过各向异性扩散和稳健统计学的联系，建立了基于B iwe ight Estim ator误差模型的扩散系数，同时利用非线性退化技术对梯度阈值的改进，提出了两个基于各向异性扩散方程的非线性滤波方法。

Population and sample, data collection and the election of variables and properly understanding of simple hypothesis, etc.

本章对实证会计研究中的总体与样本，数据的收集与变量的选取，使用简单原假设应注意的问题等，都从统计学的角度作了较深入的阐述，其中有些新意。

In view of the fuzzy characteristics of real world, fuzzy set theory and statistics with vague data are combined to generalize key theorem and bounds on rate of uniform convergence of learning processes as the base of statistical learning theory in this thesis.

摘要考虑到现实世界的模糊性，本文结合模糊集理论和模糊统计学的知识，对作为统计学习理论基础的关键定理和学习过程一致收敛速度的界进行推广，给出了模糊学习理论的关键定理和一致收敛速度的界。

This Paper mainly studies on 967 students abroad who were born, had studied Jived, worked in Su Zhou in the period from 1894 to 1949, analyzing their first time and age of going abroad, the countries and specialties they studied, the degrees and their outstanding achievements attained through the ways of history, sociology and statistics.

本文以近现代(1894年～1949年期间)在苏州出生、学习和生活过的967名苏州留学生的资料为主要研究对象，采用历史学、社会学、统计学的方法，分析了他们首次出国的时间、年龄、留学国家、留学专业、专业学位获得情况以及留学后取得的重要成就。

To explore factors of knowledge transfer and the relations between the factors and capacities of knowledge transfer (the maturity of knowledge management) in enterprises, the theories and methods of management and statistics were employed in the present study. Based on the analysis of processes in knowledge transfer and the core of knowledge management that refers to individuals, groups and organizations, a three-component model of knowledge transfer, which is the general model in this study, was obtained.

本研究主要探讨企业知识转移过程中的影响因素及其与转移能力的关系，基于管理学、统计学的理论与方法，从分析企业知识转移的根本过程出发，以个体、群体、组织为研究核心，从现有知识转移模型中推导出知识转移三元模型，通过10家企业的实证性研究，对这一理论模型进行了验证。

Note that all these demographic projections are no more than extrapolations of recent trends, together with some assumptions about the role of economic advancement and family planning in stemming the rate of population growth.
