摘　　要：运用夏皮罗-威尔克(Shapiro-Wilk)法对电子强力仪测定的苎麻单纤维断裂强力检测数据的分布特征进行了分析,结果表明其分布近似正态分布。检测数据可按狄克逊(Dixon)法进行检验,剔除异常值。分析了测定强力时产生的不确定度因素,并对其进行了评估,找出了影响测定结果准确度的主要原因。The data distribution character of ramie single fiber breaking strength was analyzed with method of Shapiro-Wilk.The result showed that the breaking strength of ramie single fiber approximated to normal distribution.The test data were checked with method of Dixon,and the abnormal value was rejected.The uncertainty of test results was evaluated,and the influencing factors were also analysed.
