| 摘 要： | 采用SEM对棒络新妇Nephila clavata腹部向上和向下在水平纱窗上爬行时纺出的拖丝、悦目金蛛Argiope amoena捕食拖丝与垂直向下缓慢纺出的拖丝及其圆网的铆钉丝进行了超微结构观察,采用电子单纤强力仪对棒络新妇拖丝与悦目金蛛圆网铆钉丝进行了力学拉伸试验.结果 表明棒络新妇和悦目金蛛拖丝均呈现出一至多根细丝纤维的多样化超微结构特征,其中悦目金蛛圆网铆钉丝还呈现出"S"形似弹簧的结构.两种蜘蛛丝的力学行为和性能与各自的功能要求相一致.蜘蛛能调节拖丝的超微结构、纤维组成和直径大小以适应其在不同环境条件下对力学性能和功能的瞬时需要.研究结果有助于拓宽和加深人们对蜘蛛丝超微结构、力学性能与生物学功能之间关系的认识和理解.

| Abstract: | The silk fibers left behind by two orb spiders,Argiope amoena and Nephila clavata,which contained the walking thread from N.clavata and predatory threads and web mooring thread from A.amoena,were observed by a Scanning Electronic Microscope.The results show the silk fibers left behind by the spiders presented a diversity in morphological structures and composition and diameter of the silk fiber,which consists of double,three,and four filaments and dozens of fibrilliform filaments with a large range diameter... |
