摘　　要：利用逆紧映射、容许覆盖等概念,将紧系统上的次可加拓扑压推广到非紧系统上,给出了次可加拓扑压的定义,并讨论了非紧系统上次可加拓扑压的性质.By the notions of proper mapping, admissible cover and so on, subadditive topological pressure of the compact system is generalized to the noncompact system. The notion of subadditive topological pressure is given and some properties of subadditive topological pressure of the noncompact system are studied.
