用扫描电子显微镜和高角X射线衍射法研究了牛主动脉壁胶原蛋白与弹性蛋白的关系。衍射图表明，4.5A和9A处的宽环由于弹性蛋白的作用，不会发生拉伸取向；另一方面，11A和2.9A处的胶原环在低伸长率时开始取向。这些数据和扫描电子显微镜一起表明，胶原和弹性蛋白之间存在着紧密的结构关系，这应该会影响所有伸长程度的变形机制。
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.
