摘要：

A new iterative approach to the solution of the Boltzmann equation is presented. The convergence of the iteration procedure is checked in reference to an isotropic solid subjected to a thermal gradient. The resulting thermal conductivity for an argon crystal at 80 K is consistent with the answer of a variational calculation previously performed in the frame of the same model. The extension of the method to any kind of transport problems, for any system of interacting particles, is suggested.
