At first, the wind tunnel test and test data process of this study are introduced in detail. A method to calculate expected extreme values of time series with a long time interval is then proposed with its sub-sections based on the classical Gumbel theory for extreme values and the independence of observed extreme values. At last, the extreme values of the wind pressure coefficients of the present wind tunnel test are calculated with the proposed method and methods used widely at present, such as peak factor method, improved peak factor method and Sadek-Simiu method.

首先 介绍了风洞试验及试验数据处理的基本概况；然后在阐述经典Gumbel极值理论的基础上，根据观察极值的相互独立性推导了短时距下极值分布参数和长时距下极值分布参数的关系式，给出了一种由短时距样本推算长时距下的极值估算方法；最后基于风洞试验数据，将常用极值估算方法(峰值因子法、改进峰值因子法和Sadek-Simiu法)和该方法的计算结果进行了比较。

The experiment results indicate that higher phase splitting speed and extraction factor can be achieved when low-carbon alcohols such as n-butanol are used as organic solvents; by using five different N-carbobenzyloxy-L-amino acids as chiral ligands that are formated with Cu(superscript 2+) or Ni(superscript 2+), it is found that as a ligand, Z-Phe has a low extraction factor, while Z-Hyp, Z-Pro, Z-Glu, Z-Val have higher extraction factors, and among these, Z-Val has the highest distribution coefficient; pH value of extractant, when near to the PI of phenylalanine, helps to improve extraction resolution effect; temperature has no obvious effect on the resolution result.

结果表明：以低碳醇类正丁醇作有机稀释剂，所用5种N-苄氧羰基氨基酸（分别为Z-Phe、Z-Hyp、Z-Pro、Z-Glu、Z-Val）与Cu(上标 2+)或Ni(上标 2+)形成手性配位体后，以Z-Val作手性配体，萃取相pH值接近苯丙氨酸等电点时，萃取拆分效果最佳。

There are complicated difficulties in Plantinga's theory. In this essay, I start from the 4th factor of warrant : leading to truth, pointing out that under certain circumstance, this factor will demand the recogniser to distinguish truth and false. This demand is in conflict with the distinction of de jure question and de facto question, meanwhile it is not coherence with the externalism position insisted by Plantinga.
