| Abstract: | Based on the traditional transfer matrix method, the ordinary differentialequations of symmetric vibration are converted to integral equations, Thetransfer matrix between two nodes is obtained by employing linear interpolatingtechnique. Furthermore, the transfer matrix of each segment is determined, andthe boundary conditions are conveyed from one end to the other by Gauss matrixelimination. It is suggested that the problem of closed shell can be dealt withby multiplying infinitisimals of appropriate order to eliminate singular factors inthe equations. |
