摘要：

An ultrasonic technique was used to measure both the elastic modulus (Young's modulus) of trabecular bone material and the elastic modulus of the cancellous structure. The average trabecular modulus, measured on specimens obtained from three human and one bovine distal femora, was 13. 0 GPa (S. D. 1. 47) and 10. 9 GPa (S. D. 1. 57), respectively. On human specimens the structural elastic modulus was found to be related to the structural (apparent) density raised to the 1. 88 power. The elastic modulus from the bovine specimens showed a more linear relationship with the density of the cancellous structure (density raised to the 1. 57 power).
