By applying an original technique, an investigation has been carried out to determine the orientation of collagen fibrils at the boundary between two successive lamellae in alternate osteons. Evidence is reported that the predominant fiber direction does not change abruptly from one lamella to the next; there is an intermediate system of criss-crossed fibers whose main orientation makes an angle of nearly 45 degrees with the direction of the fibers in the two adjacent lamellae. Taking a composite orthogonally reinforced laminate as a model, a mechanical interpretation of this intermediate system of collagen fibers is given.
通过应用一种原创技术,开展了一项研究以确定交替骨单位中两个连续骨板之间边界处胶原纤维的取向。有证据表明,主要纤维方向并非从一个骨板到下一个骨板突然改变;存在一个交叉纤维的中间系统,其主要取向与相邻两个骨板中纤维的方向成近45度角。以正交增强复合层压板为模型,对该胶原纤维中间系统进行了力学解释。
