采用超声技术和微拉伸测试来确定单个小梁和切成与单个小梁相似大小的皮质骨微标本的杨氏模量。超声和机械测量的骨小梁平均杨氏模量分别为14.8 GPa （s.d.1.4）和10.4 GPa (s.d.3.5)，骨皮质显微标本的平均杨氏模量分别为20.7 GPa （s.d.1.9）和18.6 GPa （s.d.3.5）。两种测试方法的平均小梁杨氏模量都明显小于皮质骨(p
An ultrasonic technique and microtensile testing were used to determine the Young's modulus of individual trabeculae and micro-specimens of cortical bone cut to similar size as individual trabeculae. The average trabecular Young's modulus measured ultrasonically and mechanically was 14.8 GPa (S.D. 1.4) and 10.4 (S.D. 3.5) and the average Young's modulus of microspecimens of cortical bone measured ultrasonically and mechanically was 20.7 GPa (S.D. 1.9) and 18.6 GPa (S.D. 3.5). With either testing technique the mean trabecular Young's modulus was found to be significantly less than that of cortical bone (p
