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。

With the rapid development of economic integration and constant improvement of degree of openness in the most of countries, intercourse of the trade and financial field becomes more and more frequent. Under this kind of background, economic fluctuation is easy to take place because of external shocks through foreign trade, international capital flow and other channels. So, the research of economic cycle can not be taken only in closed environment. Focusing on the open e conomy, the discussion of influence on the economic cycle fluctuation from external shocks have rather important significance.

随着全球经济一体化的迅猛发展，各国经济开放程度不断提高，各国间贸易与金融领域的交往也日趋频繁，在这种背景下，通过对外贸易、国际资本流动等渠道本国的经济将会受到外来冲击的影响而发生波动，因此，对经济周期的研究不能仅停留在封闭条件下，着眼于开放经济的背景，探讨外来冲击对一国经济周期波动的影响具有相当重要的意义。

Under the condition that coking process and ratio of coal,rank of coal were in a relative stable condition,qualitative analysis was done to the relationship among ammonia yield and residual ammonia exhausted gas entering into saturator or not,gas desulfurization unit location,the primary cooling way,blending moisture,gas collection temperature and so on,the various factors affecting degree to the yield of ammonia were concluded,in order to organize production scientifically and rationally,and provide a reference to the same industry to solve the problem of the ammonia output fluctuation.

通过对焦化厂硫铵工序的长期跟踪研究，明确了造成硫铵产率波动的主要因素，在焦化流程和配煤比、煤种相对稳定的情况下，对硫铵产率与剩余氨水蒸氨尾气是否进入饱和器、煤气脱硫装置位置、煤气初冷方式、配煤水分、煤气集合温度等因素之间的关系进行了定性分析，得出了以上各种因素对硫铵产率的影响程度的结论，以便科学合理地安排硫铵的生产计划，并为同行业解决硫铵产量波动的问题提供参考。

In this work the unhomogeneity of microstructure in product strips has been studied, and the methods to control grain size with the hot rolling technological parameters are given. The capacity to control the property unhomogeneity of hot strips has been greatly improved after using the methods. According the statistics of production, the the property unhomogeneity over 99% strips is less than 80 MPa in a batch of coils, and less than 40MPa in a coil.

The basic regulation on the changes in amount of organisms in animals was expressed by the fact that the percentages of erythrocytes being infected increased rapidly op to 96-98% 2-4 hours after infection, then it dropped down and followed by dropping and re-rising, attaining its climax up to 8 hours after infection. Finally, it reflected a fluctuating cycle of 14-16 boors.
