活体软组织的力学阻抗(mechanicalimpedance)对于理解组织的力学特性和生物声学换能器的设计是十分重要的。到目前为止,已经进行了多项研究,普遍采用Oestreicher的理论分析方法,这种无限粘弹性媒质中的振动球模型带来了便利的计算机解析解,但这种简化的有效性没有得到理论验证?
The mechanical impedance of living soft tissue is important to understand the mechanical properties of the tissue and the design of the bioacoustic transducer. So far a number of studies have been conducted that commonly employ Oestreicher’s theoretical analysis method. The vibrating sphere model in this infinite viscoelastic medium provides a convenient computer analytic solution, but this simplified effectiveness has not been validated theoretically ?
