So two methods are used to remove the local relation. One is that extremal index is introduced to POT model. The analysis showed that the introduction of extremal index improves validity and veracity of VaR based on POT model. Still VaR based on POT model introducing extremal index is invalid in low confidence level. The other is to filter returns series using GARCH model.

为此引入两种方法来消除超阈值的局部相关性：一是将极值指标引入到POT模型中，实证分析发现极值指标的引入不仅改善了POT模型估计VaR的有效性，而且还提高了POT模型估计的准确性，尽管如此在较低的置信水平上即便引入极值指标，POT模型估计VaR仍是无效的；二是用GARCH模型对收益率序列进行过滤处理。

In this thesis, we mainly study one of the topics in graph theory with applications: the extremal values of unicyclic graphs and unicyclic chemical graphs of the first general Zagreb index;the extremal values of bicyclic graphs of the second Zagreb index;the extremal values of unicyclic graphs of the general Randic index.

本论文主要研究了图论及其应用中的一个方面：图论在化学中的应用-单圈图以及化学单圈图的第一广义Zagreb指标的极值，双圈图的第二Zagreb指标的最小值以及单圈图的广义Randi指标在某个范围的最小值。

Defined object function can extract the extremal point s located accurately,form the stable extremal regions,and magnify the local intensity changes.

提出了一种基于不变区域提取算法，通过灰度指数变换，定义的目标函数不仅提取了定位准确的极值点，形成稳定的不变区域，而且突显了每个方向上灰度的变化。
