| 摘 要： | 目的：研究低频振动条件下，家兔肠、肺、肾、胃、心、肝的共振频率和振动特点，为生物体器官共振损伤及其反应研究奠定基础。方法：家兔8只，1．5％戊巴比妥钠麻醉后，将加速度传感器固定于脏器表面，兔以仰卧位固定在振动台上，施加振幅为2rnm的振动，振动频率范围为2～50Hz，测量各脏器在每个振动频率点的振幅，最大振幅对应的频率即为共振频率。结果：在2～50Hz频率范围内，家兔肠、肺、肾、胃、心、肝在前后（胸背）方向的共振频率分别为6．0Hz、5．0Hz、7．0Hz、8．0Hz、6．0Hz、7．0Hz；在共振频率处肺的振幅最大；共振频率与体重、脏器质量、脏器体积无明显统计相关性。结论：家兔主要内脏前后方向的低频共振频率为5．0～8．0Hz，其低频共振特性可能是低频波动致生物生理功能障碍和组织器官损伤的重要基础，值得深入研究。
