And it is indicated that the corrosion residual life of the pressure vessel and pipeline shouldn't be calculated with normal distribution model since the coefficients of variation of maximal corrosion depth and corrosion rate are often more than 0.2.

最后指出最大腐蚀深度和腐蚀速率等参数的变异系数往往大于0.2，因此不宜用正态分布模型进行压力容器与管道耐腐蚀剩余寿命的计算与分析。
