摘　　要：采用声传递理论及传递矩阵研究方法,从反问题角度对无限周期一维二组元声子晶体进行理论研究和方法设计。从结构参数角度进行带隙研究,并进行计算机模拟。结果表明,可以从反演的角度对带隙进行研究,从结构参数角度研究无限周期的带隙,可以设计具有某个频率范围带隙的声子晶体隔声构件,从而为实际应用开辟一条新的途径。Based on sound transmission theory and transfer matrix method,the infinite periodic one-dimentional and two-component phononic crystals are studied in view of inverse problem.The computer simulations are carried out based on the structural parameters of the phononic crystal.The results show that the bandgap of the infinite periodic crystals can be studied in view of the inverse problem with structure parameters.The one-dimentional and two-component phononic crystal sound isolation components with the bandgap in a certain frequency range can be designed with this method.
