| Abstract: | The longitudinal oscillation problem of fragment homogeneous pole is analyzed. The intrinsic value,the natural function and the natural frequency are obtained. It is studied that the influence of sonic impedance of two sides of the pole section interfaces on oscillation characteristic. |
