摘　　要：用力电类比的方法分析皮肤、肌肉等软组织及加速度计对骨声振动的影响．实验表明，加速度计的质量及加速度计与骨之间软组织的弹性系数对结果影响较大．测试频率范围应远小于加速计在软组织上的共振频率。The influence of the soft tissue and accelerometer on acoustic vibration of the bone has been investigated in vivo by force voltage analogue circuit . The result shows that the mass of accelerometer and stiffness of the soft tissue between accelerometer and bone have a signifcant influence. It is suggested that frequency to be analyzed must be lower than the resonant frequency of the accelerometer on the soft tissue and much greater than the resonant frequency of the soft tissue.
