Abstract
The elements of transfer matrix T of the displacement-stress vector is written with real and dimensionless quantities, to improve the speed and stability of the computation and to discover the relationship of some algorithms, by which it is then discovered that plane Rayleigh wave and cylindrical Rayleigh wave have exactly the same dispersion equation. The transfer matrix of F of Menke-method is written as the product of three five-order matrixes, and it is then discovered that Menke-method and δ-method have exactly the same dispersion equation; A fast and stable algorithm named scalar-transfer algorithm is deduced to further improve the computational speed.
