摘　　要：运用多重散射理论计算了二维铁-水声子晶体在不同矩形晶格和不同填充率情况下的能带结构,并详细研究了矩形晶格长宽比和填充率对禁带宽度的影响.The multiple scattering theory is applied to calculate the band structures ot some 2D iron-water phononic crystals with different rectangular lattice structures and filling fractions. The influence of filling fraction and the length-width ratio of rectangular lattice on the band gap width is discussed in detail This work is important to optimize the band structure of phononic crystal, and it could provide some enlightenment for the further theoretical or experimental research.
