Scanning electron microscopy and high angle X-ray diffraction were used to define the relationship between collagen and elastin of bovine aortic wall. The diffraction pattern shows on one hand that the broad rings at 4.5 A and 9 A, due to elastin, do not orient on stretching and on the other hand, that the collagen rings at 11 A and 2.9 A start to orient at low elongations. These data together with scanning electron microscopy suggest a tight structural relationship between collagen and elastin that should influence the mechanics of deformation at all degrees of elongation.
利用扫描电子显微镜和高角度X射线衍射来确定牛主动脉壁中胶原蛋白和弹性蛋白之间的关系。衍射图谱一方面显示,由于弹性蛋白产生的4.5埃和9埃处的宽环在拉伸时不会定向;另一方面显示,11埃和2.9埃处的胶原蛋白环在低伸长率时开始定向。这些数据与扫描电子显微镜一起表明,胶原蛋白和弹性蛋白之间存在紧密的结构关系,这应该会影响各个伸长程度下的变形力学。
