摘　　要：为了观察4种兔毛纤维的超微结构,试验以野兔、安哥拉兔、獭兔、家兔兔毛为材料,利用扫描电镜观察并比较其鳞片层的结构特征。结果表明:家兔粗毛鳞片翘角与安哥拉兔粗毛鳞片翘角之间差异不显著(P>0.05),而与獭兔相比差异显著(P<0.05),二者绒毛的鳞片翘角之间差异不显著(P>0.05);安哥拉兔毛、绒鳞片高度与其他3种相比差异极显著(P<0.01),而其他3种免毛之间两两相比差异不显著(P>0.05);安哥拉兔毛、绒鳞片厚度与其他3种相比差异极显著(P<0.01),野兔免毛与其他2种相比差异显著(P<0.05),獭兔与家兔免毛相比差异不显著(P>0.05)。4种兔毛、绒之间的碳元素含量差异均不显著(P>0.05),安哥拉兔粗毛氧元素含量与其他3种相比差异显著(P<0.05),其他3种两两相比差异均不显著(P>0.05);野兔硫元素含量与家兔绒毛中较低,与其他品种相比差异显著(P<0.05),其他品种之间两两相比差异均不显著(P>0.05);4种兔毛、绒钙元素含量均差异显著(P<0.05)或极显著(P<0.01)。说明不同种的动物纤维具有独特的形态特征,在超微结构上存在明显的差别。To observe the ultrastructure from four kinds of rabbit fibers,the hairs and villus of hare,Angola rabbit,Rex rabbit and rabbit were used as the experiment materials,and scanning electron microscopy was used to observe their scale structure.The results showed that there was no significant difference（P0.05） in the rake angle of hairs between rabbit and Angola rabbit,and a significant difference（P0.05） compared with the Rex rabbit,and no significant difference（P0.05） in the rake angle of villus between rabbit and Angola rabbit.There were highly significant differences（P0.01） in the scale height of villus and hairs from Angola rabbit compared with the other three kinds of rabbits,and no significant differences（P0.05） compared with each other among the other three kinds of rabbits.There were highly significant differences（P0.01） in the scale thickness of villus from Angola rabbit compared with the other three kinds of rabbits,and significant differences（P0.05） among hare and the other two kinds of rabbits,and no significant difference（P0.05） between Rex rabbit and rabbit.The results from energy-dispersive X-ray spectroscopy revealed that there were no significant differences（P0.05） for the content of C element in the hairs and villus from all four kinds of rabbits,and significant differences（P0.05） for the content of O element in the hairs from Angola rabbit compared with the other three kinds of rabbits,and no significant differences（P0.05） compared to each other among the other three kinds of rabbits.The contents of S element were lower in the hairs from hare and rabbit,and there were significant difference（P0.05） compared with other two kinds of rabbit,and no significant differences（P0.05） compared to each other between other two kinds of rabbit.There were significant differences（P0.05） or highly significant differences（P0.01） for the content of Ca element in the hairs and villus from all four kinds of rabbits.It indicates that the fibers from different a
