本文利用平面波展开法从理想弹性介质的弹性波波动方程出发，结合固体理论中晶格周期函数的傅里叶展开和布洛赫定理，推导出二维声子晶体的特征方程。
In this paper , the eigenvalue equations of 2D phononic crystals were deduced from the elastic motion equation of the ideally elastic media by plane wave expansion method , during which the Fourier expansion of the crystal lattice periodic functions and Bloch theorem in solid theory were used .
