摘　　要：描述金属磨损失效寿命的分布包括正态分布和威布尔分布。给出了这两种分布的表现形式，根据省煤器磨损故障数据，确定了具体的分布形式，并指出威布尔分布比较适合于工程实际，是定量分析省煤器磨损失效可靠性的一种可行方法。There are two forms to describe wear failure life of metals: normal and Weibull distributiou. The two concrete distributions are given in this paper according to wear failure data of economizers. It has also been pointed out that the Weibull distribution will be suitable for practical uses and can be used for calculating reliability of wear failure life of economizers.
