摘　　要：An optimal metliod in constructing low-dimensional dynahacal systems ofNavier-Stokes equations has been outlined in this communication. Results on closed oropen domain viscous flows show that the new method is better than the POD.An optimal metliod in constructing low-dimensional dynahacal systems ofNavier-Stokes equations has been outlined in this communication.
