摘　　要：冲击可以造成内脏广泛损伤。损伤与冲击物理特性和生物力学特性有关。试验采用2～30Hz 正弦振动,在整体与离体振动下,测定狗的各主要脏器(肺、心、肝、胃)的固有频率、阻尼比、传递比、线性。结果表明,各脏器力学特性在整体和离体振动下,差别较大,而在不同体位时差别较小。此结果可对建立模型提供基本数据。Extensive visceral injury can be caused by impact.The injury isrelated to physical and biodynamic characteristics of impact.Naturalfrequency,damping ratio,transfer ratio and linearity of the mainviscera (lung,heart,liver and stomach) in dog were measured undersine wave vibration of 2-30 Hz on the whole body and isolated organsThe results showed that the mechanical characteristics of variousviscera under whole body vibration were markedly different fromthose under isolated organ vibration.There were less differencesamong various postures.
