在体外，对绵羊的组织标本进行了电阻抗频谱分析。已对测量数据进行了处理，以减少测量中的离散度，并为组织比较提供有用的标准。提出了两种组织的电学模型，分别表现出一圈阻抗轨迹和两圈阻抗轨迹。给出了与实验数据相吻合的组织和模型的测量结果和电学参数。讨论了模型对参数变化的敏感性。
In vitro electrical impedance spectrometry was performed on tissue samples excised from sheep. Measured data have been processed to reduce dispersion in measurements and to provide criteria useful for tissue comparison. Two electrical models are proposed for tissues exhibiting a one-circle impedance locus and a two-circle impedance locus. Measurement results and electrical parameters of tissues and models fitted to experimental data are presented. Model sensitivity to parameter variations is discussed.
