摘要: Summary. The symmetry of the differential system for elastic waves, previously noted plane geometry, is extended to any linear and, in particular, elastic-gravitational vibrations a spherical earth. result remains valid linearly viscoelastic medium. allows inverse propagator matrix be obtained by simply ‘transposing’ elements propagator. With this result, it shown how source excitation using particular integral can put more instructive form, comparable with normal modes.
