The results of research show GED can display features-tailed more exactly than student's t distribution and gauss normalized distribution. Meanwhile, two models of EGARCH and PARCH are better than others GARCH model.

实证分析结果表明，与正态分布和t分布相比，GED分布能较好的反映股市收益率回报序列的厚尾特征，同时使用GARCH类模型预测VaR值时，EGARCH和PARCH模型要优于其他模型。

In the empirical analysis part, statistical descriptions on the sample funds are made firstly, which show that the actual distribution of each sample fund"s daily net value return possesses the characteristic of leptokurtosis. So it is necessary to add student T distribution and GED to capture such leptokurtosis characteristic other than normal distribution. Secondly, ARCH test shows that there exists volatility clustering in each sample fund"s daily net value return, so GARCH related models should be used to describe such volatility clustering characteristic.

实证分析部分首先对样本基金进行统计描述，得出其收益序列均存在尖峰厚尾特征，不服从正态分布，因此有必要在下面的VaR计算中加入T分布和GED分布来捕捉这种尖峰厚尾特征；并且经ARCH检验后得出收益序列存在明显的波动聚集性的特征，因此可以选择GARCH类模型来描述这种特性，经过模型筛选，得出最适合我国开放式股票型基金的收益波动性模型为GARCH(1，1)模型。

We first check the VaR of the automobile physical damage insurance via P-P Plot and Q-Q Plot, we compare normal, log- normal, index and student t distribution to discover the amount of losing money and probability above were unable to mix rightly.

经由P-P Plot 及Q-Q Plot来检定汽车车体险损失的风险值，我们同时比较了常态、对数常态、指数分配及t分配等四种分配函数。

So people want to prove which asset classes are likely to satisfy the subadditivity.

Mainly belonged to Loranthaceae. Plants of Phacellaria Benth. and their hosts were mainly distributed in tropical and subtropical area. Plants of Phacellaria Benth. maybe originated in tropical area in the south of China before Tertiary. Their ancestors were parasitic on ancestors of some plants of Loranthaceae by chance during Tertiary. It took them millions of years to form a sturdy relationship between parasites and hosts. Ph. rigidula was a hemi-parasitic subshrub. In area observed, its host was mainly Taxillus caloreas var. fargesii.

的硬序重寄生(Ph.rigidula)及其寄主植物做为研究植物与植物间协同进化的材料，对重寄生属植物的起源、与其寄主的分布、硬序重寄生的形态学特性、解剖学以及化学成分进行了研究，结果表明：重寄生属植物主要寄生在桑寄生科植物上，分布区与其寄主的基本一致，均主要分布在东南亚和中国南部的热带与亚热带地区；重寄生属植物可能起源于第三纪之前某一时期的华南热带地区，随后向周边地区扩散。
