In this paper,we will prove that the system of differential-difference equations{(f(z)f'(z))n+p21(z)gm(z+η)=Q1(z),(g(z)g'(z))n+p22(z)fm(z+η)=Q2(z),has no transcendental entire solution(f(z),g(z))with ρ(f,g)<∞ such that λ(f)<ρ(f)andλ(g)<ρ(g),where P1(z),Q1(z),P2(z)and Q2(z)are non-vanishing polynomials.
