| 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%. |
