摘　　要：在塔器的可靠性强度设计中,需要进行各种随机变量的统计分析.为了统计分析其中的随机变量之一地震时最大地面水平加速度,文中提出了一种利用Excel生成概率纸并得到其分布参数的方法.用此方法不仅可以在没有现成概率纸的条件下确定分布参数,而且还可以直接用来判断所采集的样本是否呈威布尔型极值分布.该方法简单易学,方便实用.　In the design of mechanical strength reliability of tower vessel,all kinds of random variables need to be analyzed statistically. In order to do so for one of these variables — the maximal horizontal acceleration of ground surface during earthquakes, a method of probability working-paper generated by Microsoft Excel is presented, and through it the distribution parameters of that acceleration is determined and, in addition, the distribution parameters can be expressed on this working-paper. Through this method, not only the distribution parameters are determined without ready-made probability paper but also can we judge if the collected sample exhibits as the Weibull extreme value distribution. This method is simple, easy to learn, practical, and convenient.
