摘要: Summary. Exact solutions of the reduced Helmholtz equation are derived for case a spherically symmetric medium in which velocity has form v = arPb. If Earth is modelled shells this type then these can be used to approximate radial wave functions needed body-wave computations. The spherical layer matrix technique adapted where velocities vary smoothly within layers.
