摘　　要：A two-grid method (TGM) for the fully discrete unsteady NavierStokes (N-S) equations in a penalty form is discussed. An error estimate is given,and a numerical test is also given to verify the correctness of theoretical analysis.A two-grid method (TGM) for the fully discrete unsteady Navier-Stokes (N-S) equations in a penalty form is discussed.
