摘　　要：本文应用扫描电镜 (SEM)技术观察大腹圆蛛丝的形态 ,结果表明 ,大腹圆蛛的拖牵丝是由单根、双根、三根、四根的单丝纤维组成 ,且这四种形态的拖牵丝表面也有区别。其包卵丝的伸长率、断裂强度与拖牵丝相当 ,但包卵丝的刚性逊于拖牵丝。The silk shape of Araneus ventrocosus was investigated by scanning electron microscope (SEM). The results showed that the towing silk of Araneus ventrocosus was composed of simple fiber of one branch,two branches,three branches and four branches. There were differences among these four kinds of silk. The drawing ratio and breaking intensity of the silk of covering eggs were as much as the towing silk,but the rigidity was inferior to the towing silk. There was no much difference on towing silk between the Araneus ventrocosus and other kinds of spider.
