摘要
应用数理统计方法,对超高压容器的爆破压力进行分析,得到两个结论:1描述爆破压力实测值与理论值之比的随机变量基本符合正态分布;2在双侧置信度为98%时,该随机变量分布参数范围为:均值应不小于0.984 50且不大于1.070 3,标准差应不小于0.071 82且不大于0.133 95,变异系数应不小于0.06710且不大于0.136 06。
By using the method of statistics,the burst pressure for the super- high pressure vessel is analyzed. The results shows that： 1the random variable describes the ratio of the measured value to the theoretical value for bursting pressure accords with normal distribution; 2with 98% of the bilateral confidence limit,the distribution parameters range of the random variable follows： the average value should be not less than 0. 984 50 and not greater than 1. 0703,standard deviation not less than 0. 071 82 and not greater than 0. 133 95,and variation coefficient not less than 0. 067 10 and not greater than 0. 136 06.
