国产长强棉花标准样品稳定性研究OA
Study on stability of domestic long strong cotton standard sample
探讨国产棉花标准样品的长强指标随时间波动的情况.以国产长强棉花标准样品(25 mm级、26 mm级、28 mm级)为研究对象,通过采集两年时间内各标准样品的上半部平均长度、马克隆值、长度整齐度指数和断裂比强度等核心指标数据,采用独立t检验等方法系统分析标准样品特性参数的统计学差异.结果表明:国产棉花标准样品的上半部平均长度、马克隆值、长度整齐度指数和断裂比强度等指标参数在两年内基本无显著变化,仅有28 mm级样品上半部平均长度在24个月的时间节点呈现轻微波动.总体来看,国产棉花标准样品在两年内的稳定性表现良好.
Situation of domestic cotton standard sample long strong index fluctuating with time was discussed.Domestic long strength cotton standard samples(25 mm grade,26 mm grade,28 mm grade)were selected as research object.By collecting core indicators,such as upper half mean length,Micronaire value,length uniformity index and specific breaking strength within two years,independent t test and other methods were used to systematically analyze the statistical differences in characteristic parameters of the standard samples.The results showed there was no significant change in upper half mean length,Micronaire value,length uniformity index and specific breaking strength for the domestic cotton standard sample within two years,with only slight fluctuations in the upper half mean length of 28 mm grade sample at the 24 months time point.Overall,the stability of domestic cotton standard samples within two years is better.
