摘要：

Three different methods for solving the inversion of the specific heat for the phonon density of states are presented and discussed. The iterative formalism is first presented in this paper. Based on an old theorem in number theory, a new expression for the solution is presented with asymptotic behavior in the low frequency region. The Fourier convolution method has proved to be successful for numerical calculation. The existence, uniqueness and stability have been discussed. © 1990.
