中文摘要：

在分析、统计夏季室外高温数据的基础上，引入频率分析法，采用皮尔逊-Ⅲ型分布对夏季室外高温参数的极值分布进行了模拟。并以北京地区1951～1981之间30年气象参数为例，得到其不同保证率条件下的夏季高温分布图。研究使用分布检验了模型拟合效果，结果显示，上述模型能较好的反映真实气象状况。研究为不同标准层次HVAC系统设计气象参数的选取提供了有益补充，并可供相关研究参考。

英文摘要：

Based on analysis of the outdoor high temperature data from 1951 to 1981 in summer in Beijing,using frequency analytical method to imitate the high temperature data by Pearson-Ⅲ distribution,the high temperature distribution of Beijing has been gained,then the simulated effect is tested by distribution. This paper provides available complementarities for the selection of weather parameter for different HVAC design standard, and can be consulted by correlated research.
