摘　　要：在振动问题中,同一条件下的粘弹性材料和弹性材料的振型函数相同;粘弹性问题的频率方程可以从对应的粘弹问题的频率方程通过本构关系参数的相应代换得到;粘弹性体的波速也可由弹性固体的对应波速作相应的代换得到。For vibration problem, every mole shape of viscoelastic materials is as same as that of elastic materials at same boundary condition. The frequency equation of viscoelastic problem can be obtained from the relevant equation of elastic problem by relevant replacement of constitutive parameters. The spceed of wave in viscoelastic solid can be also obtained by correspondent replacement from an associated problem of elastic solid.
