摘要：

The Bloch equation models the evolution of the state of electrons in matter described by a Hamiltonian. To model more physical phenomena we have to introduce phenomenological relaxation terms. The introduction of these terms has to conserve some positiveness: properties. The aim of this paper is to review possible relaxation models and to provide insight into how to discretize them properly in view of numerical computations. (C) 2001 Academic Press.
