摘要
为探索检测骨骼密度的新方法 ,根据波的传播原理 ,采用实验力学的敲击响应法 ,使用敲击小锤、传感器、放大器、瞬态波形存储器等 ,对生理状态下人体胫骨中的波传播速度进行测试。结果表明 ,实验可重复性好 ,对骨密度的分辨率高 ,能有效判断早期骨密度改变。
BaSed on the principle of wave propagation,to explore a new method of testing bone density,we applied the knock response method in experimental mechanics to measure the wave velocity in human tibia under physiological state with a hammer,sensor amplifier and transient wave form memoriser.The results show that the experiment has strong resolving power,can recognize ealy changes in bone density efficiently and can be well repeated.
