The Young's modulus of elasticity, the calcium content and the volume fraction (1-porosity) of 23 tension specimens and 80 bending specimens, taken from compact bone of 18 species of mammal, bird and reptile, were determined. There was a strong positive relationship between Young's modulus and both calcium content and volume fraction. A power law model fits the data better than a linear model. Young's modulus has a roughly cubic relationship with both calcium content and volume fraction. Over 80% of the total variation in Young's modulus in this data set is explained by these two variables.
测定了取自18种哺乳动物、鸟类和爬行动物致密骨的23个拉伸试样和80个弯曲试样的杨氏弹性模量、钙含量和体积分数（1-孔隙率）。杨氏模量与钙含量和体积分数之间存在很强的正相关关系。幂律模型比线性模型更适合这些数据。杨氏模量与钙含量和体积分数大致呈三次方关系。在该数据集中，杨氏模量总变化的80%以上可由这两个变量解释。
