对薄板波动方程的一般解应用边界条件得到无限大薄板中弯曲波的解.进一步得到弯矩特性阻抗和剪切力特性阻抗的表达式,并给出了阻抗的曲线图.%The solution for flexure waves in an infinite plate is obtained by using boundary conditions to the general solution of the thin plates wave equation. Then the expressions for a bending moment characteristic impedance and a shear force characteristic impedance are obtained, and the graphs of these impedances are presented.
