摘要：

Tagged particle properties, such as the diffusion coefficient and velocity autocorrelation function, are calculated in the mean-field approximation for all standard lattice gas cellular automata defined on (hyper)cubic, square and triangular lattices and on a line. Tagged particle dynamics is introduced through maximally random or minimally random collision rules. For a completely filled lattice the former reduces to a random walk, the latter to ballistic motion.
