Abstract: The fatigue test data often include some censored data,which are commonly omitted when treating them,while the authors believe is unreasonable.Accordingly,assuming the data follow the normal (or logarithm normal) distribution,a method on the treatment of such problems is derived on the basis of statistics,and then an example is given with the method.It is found that the method is viable to treat the fatigue test data involved some censored data

Key words: fatigue test, censored data, normal (or logarithm normal) distribution, statistics

摘要: 水泥砼疲劳试验数据中常含有非破坏数据,人们在处理数据时常将其剔除,笔者认为这是不合理的。据此, 笔者应用数据统计方法,假定数据服从正态(或对数正态)分布,从理论上推导出了处理这类问题的计算方法,并 给出了具体算例。分析发现,应用该方法处理疲劳试验数据中含非破坏数据是可行的
