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.

Among them,the variations of Pelshenke fermentation time,vitreousness,grain hardness,mixing time,SDS sedimentation volume were large,while those of starch content,protein content was small,variations of AWRC and amylose content were determined by wheat vrieties and environments,but variance of swelling power,SDS sedimentation volume mainly by varieties,PPO activity by environments.2 All quality indices except protein content,PPO activity,mixogram bandwidth in 7 minutes,amylose content and swelling power were high correlated with AWRC.

从安徽不同生态条件下选取的小麦样品其品质性状存在很大的差异。变异较大的有Pelshenke值、籽粒角质率、硬度、和面图指标、SDS沉降值等，变异较小的是总淀粉含量、蛋白质含量等。AWRC、直链淀粉相对含量既受品种差别的影响，又受环境的影响；麦粉膨胀势、SDS沉降值的差异则主要受品种的影响。而PPO活性则主要受环境的影响。
