Abstract
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.关键词
