中文摘要：

多孔材料声学模型的研究,对多孔材料在吸声降噪、冲击吸能等领域的应用具有重要意义。对基于流体惯性和黏滞耗散理论且同时考虑热传导效应建立的声传播模型进行简要介绍,并具体描述圆管理论模型和JCA模型,分析总结这些声学模型在近年来科学研究中的应用。结果显示,传统的圆管理论声学模型有其理论合理性,但在精度上有一定的局限性,仍需要更多学者的努力和完善。

英文摘要：

Acoustic models for porous materials play an important role in their applications to sound absorption,noise reduction,energy absorption,and so on.The sound propagation models based on fluid inertia and the theory of viscous dissipation,as well as the thermal conduction effect are summarized,especially the cylinder model and JCA model.The applications of such models are also summarized and analyzed.The results show,the traditional cylinder model is theoretically rational,but lacks absolute precision which needs further efforts of researchers.
