摘要:

研究了在日历寿命确定中的分散性问题,通过对金属腐蚀试验数据分布规律的研究,选定了符合这种规律的分散系数计算模型;通过这些腐蚀试验数据,计算出已试验材料的标准差;通过给出的标准差计算出腐蚀试验用的分散系数的取值。

Abstract:

This paper studies the scatter factor of calendar life, and through research on the distribution regularities of the test data of metallic corrosion, a calculation model of scatter factor which is in consistence of the regularities is determined. Standard deviation is calculated through the corrosion test data. Scatter factor value used in corrosion test is calculated by the given standard deviation.

Key words: metallic corrosion, calendar life, standard deviation, scatter factor, corrosion test
