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。

These factors have seriously influenced the security and economical operation of the unit. This paper firstly summarizes the research background and the general situation of resarch about the overheating problem of boiler's high-temperature surface ,introduces the aspects and research findings in this field such as flux deviation、thermal deviation、flue gas velocity deviation at the exit of furnace and tee bends,et al.Then analyses the reason why high-temperature surfaces are overheated from such aspects as design、manufacture、operation, et al and points out one of the main factors that cause the overheating of reheaters is the flue gas velocity deviation caused by the remaining turning at the exit of furnace.
