摘　　要：本文根据骨的微观结构；运用复合材料力学中的方法，构造了骨板的本构关系。建立了骨单元的微观结构模型，并给出该模型轴对称应变问题的解析解。根据该模型可知，密质骨的宏观弹性系数不仅与骨的孔隙率有关，而且还与骨组织中胶原和矿物质的含量以及胶原纤维的排列方向有关。Based on the ultra structure properties of bone, the constitutive relation of lamellae bone and theultra structural model of osteon were provided with the method in the mechanics of composites. Theaxisymmetry strain problem of the osteon was solved. This model shows that the elastic coefficientsof conical bone are not only the function of bone porosity, but also the functions of the content ofcollagen and mineral and the orientation of collagen fibres.
