生丝回潮率检验样丝绞数的探讨

Discussion about Sample Skein Number for Test Moisture Regain of Raw Silk

将生丝回潮率检验的样丝随机分为两组 ,并将分组单独测试回潮率的结果与其平均值进行比较 ,按置信区间计算方法判定生丝回潮率检验样丝绞数在保证检验结果准确的前提下 ,可在现行标准规定的基础上减少一半 ,从而节约大量的样丝 。

It is divided the sample skein for testing the moisture regain of raw silk into two groups at random, then compared each of the test results with the average value. Calculated by the methods of confidence interval, it is determined that the sample skein number can be cut half of the present standard required on the basis of the test results being precise. So it can save large amount of sample skein and bring economic benefits for enterprises.
