【Abstract】 For the linear large-scale system with variable time dx/dt=A（t）x+f（t） where A（t+w）=A（t）,f（t+w）=f（t）,we have s decompositionwhere A_ss is an n_s×n_s constant matrix and the eigenvalues of A_ss have negative real parts.Using the method of Lyapunov function,we give the concerte bounds of correlation terms so that the large-scale system may have a unique periodic solution with period ω.更多还原
