摘　　要：Let a,b be two positive integers such that a≤b and a≡b(mod 2).We say that a graph G has an(a,b)-parity factor if G has a spanning subgraph F such that dF(v)≡b(mod 2)and a≤dF(v)≤b for all v∈V(G).In this paper,we provide a tight spectral radius condition for a graph to have(a,b)-parity factors.

关 键 词：Spectral radius [a b]-factor (a b)-parity factor
