摘要： 用数理统计方法分析不同状态的合金试样用动态磨损试验方法所得的磨损试验数据,可较准确地判断出两两相互对比合金的耐磨性能有无本质差异.

关键词: 磨损试验；数理统计；正态分布； t检验；

Abstract: The experimental data of various stated alloys in the dynamic wear test have been studied with mathematical statistics.According to the results,it could be exactly determined whether there is no obvious difference between one stated alloy and the other.

Key words: dynamic wear test； mathematical statistics； normal distribution； t testing；
