| 摘 要： | 对马(20)、骡(10)蹄角质的测定结果表明,硬度、弹性,抗张强度、弹性模量均为蹄壁>蹄底>蹄叉;蹄底的磨耗大于蹄壁;蹄壁的磨擦系数大于蹄底;蹄壁纵向拉伸的抗张强度大于其横向拉伸,强度越大其伸长率越小;在相同压力下,蹄壁侧压弹性模量值大于纵压值,而蹄底侧压模量值则小于纵压值;蹄角质在材料力学上表现为一种各向异性的特点。作者认为,马、骡蹄角质物理性能的差异与蹄病的发生密切相关。

| Abstract: | The experimental results showed that the values of hardness, elasticity, tensile strength and modulus of elasticity of the sole were significantly less than those of wall in the same hoof, whereas the values of frog were still less. However, the wear of sole was by far greater than that of wall, on the contrary, the friction coefficient of wall was significantly greater than that of sole Hoof horn is mechanically anisotropic, i.e., the values of tensile strength of wall in the longitudinal drawing were significantly greater than those of wall in the transversal direction. Onder the same pressure, the lateral modulus values was significantly greater than the longitudinal modulus value in the wall, and lateral modulus value was significantly less than the longitudinal value in the sole. |
