摘要
本文给出了一种新的单侧容限系数ｈ，比目前使用的单侧容限系数ｋ更接近于母体百分位值的置信下限。应用比较分析显示，新方法在试验中能够节省大量试件，而且在试件数ｎ越少、可靠度Ｒ越高或置信度γ越大时，新单侧容限系数的优越性越明显。
A new one一side tolerance factor is presented.As a result,we may obtain a lowconfldence limit of the population percentile by means of the factor.Application and ana-lysis show that a lot oftest samples can be saved with the new method and the advantage ofnew one一side tolerance factor is clearer when the number of test-sample is smaller, relia- bility is higher or confidence limit is larger.
