▎ 摘　　要

Possible stably ordered substitutional structures based on a graphene-type crystal lattice are considered. A kinetic model of atomic ordering in metal-doped graphene with stoichiometric (1/8, 1/4, 112) and nonstoichiometric compositions is developed. Inasmuch as the intrasublattice and intersublattice 'interchange' ('mixing') energies are competitively different for graphene-based lattice, kinetic curves of the long-range order (LRO) parameters may be nonmonotonic for the structures described by two or three LRO parameters.
