摘要: Abstract The equations of Ying and Truell, Waterman describing the propagation ultrasound in two-phase materials are solved numerically for porous solids, found to give unphysical results high porosity. A new self-consistent theory, which can be analytically, is presented shown have reasonable behaviour at
