摘　　要：采用光学法和力学法测定8种单根纤维与水的接触角,通过数据统计比较两种测试方法的显著性差异,并对其测定结果进行相关性分析。试验结果表明:所选用的测定方法均可适用于竹麻等细短纤维接触角的测定,两种测定方法不存在显著性差异(P>0.05),力学法和光学法测定结果相关系数为0.812,呈显著相关(P=0.002<0.05)。In this paper, 8 kinds of single fibers are characterized successfully by two common measuring methods of contact angle - optical method and force method. All experimental data are analyzed statistically, and correlation analysis of measured results between optical and force method is carried out. The results show that both methods can be used for various fine fibers with short length, such as bamboo and hemp fibers, more- over, optical method and force method have no significant effects on the single fiber contact angle （P〉0.05）. Correlation coefficient of measured results between optical and force method is 0.812, which presents significant correlation （P=0.002〈0.05）.
