This article aims to study how a thermoelastic medium having a bipolar nature is impacted by diffusion. It employs an analytical method called normal mode analysis to derive the formula for required physical quantities. The paper utilizes Green-Naghdi theory (G-N III) along with the three-phase-lag (3PHL) model to solve the existing problem. The comparisons are established graphically for different values of the phase-lag times, the presence and absence of diffusion, and the time parameter with respect to Green-Naghdi theory and the 3PHL model.

3PHL模型下扩散对微极热弹性介质的影响

本文旨在研究具有双极性质的热弹性介质如何受到扩散的影响。它采用称为常模分析的分析方法来推导出所需物理量的公式。本文利用 Green-Naghdi 理论 (GN III) 以及三相滞后 (3PHL) 模型来解决现有问题。相对于 Green-Naghdi 理论和 3PHL 模型，针对相位滞后时间的不同值、扩散的存在和不存在以及时间参数以图形方式建立了比较。
