本文测定了家兔跖骨灰分含量与弹性模量、静态强度、破坏功和冲击强度的关系。在灰含量的范围内观察到的静强度和弹性模量与灰含量线性增加。在静态和动态载荷下，骨材料所能吸收的能量随灰分含量的增加先增加后减少。能量吸收的最高值大致在灰分的中值处。有人提出，这个值是生命中的最佳值，因为骨头通常会因撞击而断裂，能量吸收在抵抗撞击中很重要。给出了能量吸收上升和下降的原因的简短讨论。
The relationship between the ash content of rabbits' metatarsals and their modulus of elasticity, static strength, work to failure and impact strength was determined. Over the range of ash contents observed the static strength and the modulus of elasticity increased linearly with the ash content. The energy that could be absorbed by the bone material, in both static and dynamic loading, increased and then decreased with ash content. The highest values for energy absorption were roughly at the median value of ash. It is proposed that this value is the optimum value in life, because bones are usually broken by impact, and energy absorption is important in resisting impact. A short discussion of the reason for the rise and fall in energy absorption is given.
