摘要：
A Lower energy duality string model with time dependent metric, torsion, dilaton background field and Liouville potential field is studied in this paper. A classical string cosmological solution in D = 3 space-time dimension is obtained. By means of O(2,2) duality transformation, we find that a new cosmological solution containing singular points can be generated.
