生丝纤度偏差与纤度分布

Raw Silk Size Deviation and Distribution

根据生丝纤度正态分布性质,运用数理统计及概率论,提出在生产中为使生丝纤度偏差达到等级要求,生丝纤度分布应控制在一定范围内。对如何在每次生产中确定纤度控制线和纤度允许线,文章提供了一条思路,并提出适用的简单计算方法。

On the basis of the normal distribution property of raw silk size, a certain limit for controllingraw silk size distribution is set by statistical and probability methods so that raw silk size deviationin the production will meet acceptable grades. This article gives a clue for determinating thecontrollable and permissible lines of desirable szies, and offers a simple calculating method.
