摘要：

Some recent results on non-conservative models of self-organized criticality are reviewed and discussed. A class of deterministic models introduced by Olami, Feder and Christensen exhibits 1/f noise with an exponent which depends on the degree of conservation. The ''Game of Life'', a cellular automaton mimicking a society of interacting organisms, also appears to evolve to a critical state, with avalanches obeying finite size scaling.
