摘要: 本文对白唇鹿被毛的形态进行了宏观及扫描电镜观察研究。结果表明,其被毛仅由针毛组成。针毛的毛径特粗,髓质极发达,髓质指数高达96%;髓质形态为蜂窝状网格型,皮质呈退化状态。针毛具有很强的保温性,是适应高寒环境的重要特征之一。

Abstract: The microscopic and submicroscopic Structure of the covering hair of whitelipped deer has been stttdied. The result indicated that the covering hair of white-lipped dear is only composed of needle-shapsd hair. The needle-shaped hair is very wide in diemeter, its medulla is very dcveloping and the morphology of medulla is honeycombed lattice type. The medulla exponent can reach 96% .The characteristic of degoncration in cortx was found. The presservation of heat of neddle-shaped hair is more effective. This is an important feature of adaptation to alpine environment.
