摘　　要：利用热拉伸获得不同性能与结构形态的PGLA(GA/LA摩尔比=90/10)纤维,并进行体外降解实验。在降解过程中,采用DSC、傅里叶红外光谱、扫描电镜等测试手段对PGLA(90/10)纤维的性能与形态变化进行研究。结果表明,热拉伸显著改变PGLA(90/10)纤维的降解特征。The PGLA （GA/LA molar ratio = 90/10） fibers with different properties and structural morphologies were obtained by heat-stretching treatment and were tested in vitro degradation. In the degradation process, the structures and properties of the PGLA（90/10） fiber have been investigated by means of DSC, infrared spectroscopy, scanning electron microscopy and other testing methods. The results show that, heat drawing can vary the degradation characteristics of the PGLA（90/10） fibers significantly.
