Employing the Laplace transform and its properties, we investigate the evolution of the coupled thermal and fluid-acoustic waveforms that arise in a signaling problem under the Eringen–Cattaneo–Christov–Straughan model of poroacoustic phenomena. Assuming a Heaviside temperature input, we determine the effects of what we term the “Eringen coefficient” by examining the propagation and evolution of the resulting shock and/or acceleration waveforms. Special/limiting cases are also discussed and, in the final section of this Note, possible follow-on studies are suggested.

线性化 Eringen-Cattaneo-Christov-Straughan 模型下的孔隙声前传播

利用拉普拉斯变换及其特性，我们研究了多孔声现象 Eringen-Cattaneo-Christov-Straughan 模型下信号问题中出现的耦合热和流体声波形的演变。假设输入海维赛温度，我们通过检查所产生的冲击和/或加速度波形的传播和演变来确定所谓的“埃林根系数”的影响。还讨论了特殊/限制性案例，并在本说明的最后部分中建议了可能的后续研究。
