摘要
本文分析了充流体管中由点源激发的对称模式弹性波。数值计算了各子波的相速度、群速度色散曲线,导出了各子波的势函数振幅表达式。
Trasmission properties of symmetrically guided modes excited by a spherically symmetrical impulsive point source in fluid-filled tube are investigated. Phase velocity andgroup velocity dispersion curves are plotted. Potential function for amplitudes of waveletsare derived, also.
