-
摘要: 从二维周期性结构的振动方程出发,建立二维带隙计算模型,并在此基础上分析带隙与材料结构特性的关系。实例数值计算结果证明,理论结果与试验仿真计算结果是一致的。Abstract: By analyzing 2D were calculated and studied. The numerical the vibration model of two-dimensional the connection of the elastic wave band (2D) , the elastic wave band gaps of gaps with material characteristic was calculation results and the experimental results matched by the experiment.
