【摘要】 为了检验国产动物纤维细度自动测量仪奥达2000的稳定性和准确性,分别用进口的OFDA100细度仪和国产动物纤维细度自动测量仪对来自314只细毛羊的毛样进行测定,再对两者测得的数据作配对性t检验。检验结果表明,二者间差异不显著(P>0.05)。因此,国产动物纤维细度自动测量仪奥达2000性能与OFDA100细度仪没有差异,可以代替进口细度仪OFDA100。更多还原

【Abstract】 To test the accuracy of domestic fibre diameter measurement instrument,AODA2000,wool samples from 314 wool sheep and foreign fibre diameter measurement instrument,OFDA100,were used.Each sample was measured by the tow instruments(AODA 2000,domestic;OFDA100,imported),respectively.Then,the Paired-Sample T Test was done.The results showed that there was no significant difference(P>0.05) in fineness measurement between the two instruments.Therefore,there is no difference between AODA2000 and OFDA100 in measuring fire diameter,and the AODA2000 can take the place of OFDA100.更多还原
