通过对弹性波在蜂窝结构中传播的研究，建立了弹性力学基本方程，得出了截止频率；再根据吻合效应产生的频率，从理论上得出了影响蜂窝结构的隔音因素，为蜂窝纸板的隔音性研究提供理论依据。

The fundamental equations of elastic mechanics were established through research of the spreading of elastic wave in honeycomb structure. The cut-off frequency was solved from the equations. According to coincidence effect, the sound insulation factors of honeycomb structure were obtained. The purpose was to provide theoretical basis for insulation performance study of honeycomb cardboard.
