With the wide development of the mixed Poisson distribution in the medical, financial and insurance applications, it is receiving increasing attention. But, according to the author to understand, at present, studies on the Mixed Poisson distribution of the literature are relatively small, the most important reason is that it does not have a Mixed Gaussian distribution of a wide range of applications. However, with advances in computer technology and the development of statistical techniques, Mixed Poisson distribution analysis of statistical data will play an increasingly important role, thus the system in detail study of Mixed Poisson distribution model parameter estimation is necessary.

随着混合泊松分布在医学，金融保险等领域的应用越来越广泛，因此它越来越受到人们的重视，但是据作者了解，目前，对混合泊松分布研究的文献是比较少的，其中最重要的原因是它没有混合正态分布的应用范围广泛，但是随着计算机技术的进步和统计技术的发展，混合泊松分布将在统计数据分析中扮演越来越重要的角色，因而系统，详细的研究混合泊松分布模型的参数估计是非常有必要的。

Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.

为了解住在台湾的中国人其牙齿的大小，齿列弓幅径及形态，为齿科人类学上的特微，以期能对儿童牙科，齿颚矫正科之临床及齿科基础医学能有所贡献，抽取12岁学童男女各30名共60名，可接受为正常咬合之上下颚齿列模型，测量其上下颚(1)左侧正中门牙到第一大臼齿共计12颗恒牙之牙冠近远心径，(2)齿列弓宽径、长径及齿槽基底宽径、长径，(3)齿列弓之形态，以上资料经统计分析作t-test检定，并与诸学者对日本人、北美白人、中美及南美印第安人人种的研究结果作检讨得知；(1)男女性恒牙的近远心径无明显差异，但男性上颚第大臼齿比女性者大，下颚正中门牙比女性者小；(2)男性的齿列弓幅径比女性者为大，尤以齿槽基底宽径及长径最显著；(3)国人男子的牙齿近远心径比其他四人种者为小，特别是国人的上颚犬齿，下颚正中门牙及第一大臼齿最小。

There are totally five chapters in the paper. Chapter 1 is the introduc-tion,and extreme value theory and methods and modelling for returns fat tails are introduced systematically in Chapter 2.This chapter also presents mean excess function and de Haan's moment estimate to decide on the reasonable exceedance threshold. Chapter 3 describes in detail non-linear time series mod-els such as GARCH models and the corresponding statistical inferences,and it also gives modelling and statistical analysis methods for returns series. Chap-ter 4 uses the models in Chapter 2 to analyzes the daily returns for Shanghai complex index and Shenzhen complex index in the Shanghai and Shenzhen stock markets. Chapter 5 applies the models in Chapter 3 to the volatility analysis of the two stock indices returns.

论文总共五章：第一章是引言部分；第二章系统介绍了极值理论方法和收益率厚尾的建模方法，给出了平均剩余函数法和de Haan矩估计相结合的方法确定合理的超越门限；第三章详细论述了非线性时间序列模型GARCH类模型及其统计推断，并且给出了收益率时间序列波动的建模和统计分析方法；第四章利用第二章的模型对国内沪深两市大盘指数上证综指和深证综指日收益率数据分布的厚尾进行了实证分析；第五章将第三章的模型应用到两个股指日收益率时间序列的波动分析。
