The elastic wave equation is derived from the motion equations of atoms in longwavelength acoustical lattice waves，that is，the macroscopic elastic waves are unified with themicroscopic motions of atoms in long wavelength acoustical waves．The result shows that thelong wavelength acoustical lattice waves are namely elastic waves.
从原子的运动方程出发，把长声学格波的原子运动方程演化成弹性波的波动方程，将长声学格波条件下的微观原子运动与宏观的弹性波波动统一起来，对长声学格波即弹性波作了进一步的证明。
