摘　　要：组织工程支架的组织与结构是影响支架性能的基本要素,它对组织工程的功能及其最终应用起着重要作用。探讨了组织工程用编织型神经再生导管孔隙率的表征方法。导管使用聚乙丙交酯(PGLA)纱线,采用三轴向编织而成。采集导管二维图像后,用图像处理方法得到孔隙率。讨论了导管孔隙率与编织纱线密度、编织角度、编织机绽数、导管直径等编织参数的关系。The structure and architecture of scaffolds are elemental factors in scaffold-based tissue engineering as they affect the functionality of the tissue engineered constructs and the eventual application in health care.This paper mainly discussed the characterization of porosity of braided nerve tube for tissue engineering,manufactured with poly(glycolide-co-L-lactide)(PGLA) yarns and triaxial structured.In this approach,the author describes the surface of this kind of tubes with microscope and examining the p...
