摘    要:应用数理统计方法,对液化石油气钢瓶爆破强度进行了分析,得到如下2个结论:①在显著度为5%时,描述爆破强度实测值与预测值之比的随机变量符合正态分布;②在置信度为99%时,分析得到了该随机变量分布参数的取值范围。

关 键 词:液化石油气  钢瓶  爆破强度  概率分布  数理统计  显著度  置信度

Abstract:In this paper,the bursting pressure of the steel bottle liquidized petroleum gas is analyzed,by using the method of statistecs and two results are obtained,that is,the random variable of the ratio between the measured value and the expected value with normal distribution is described when the marked value is 5%;and the distribution parameter of the random variable is obtained when the confidence limit is 99%.
Keywords:the steel bottle liquidized petroleum gas  bursting pressure  random variable probability  parameter
