Abstract
The low energy duality string model is investigated in time-dependent metri c, torsion, dilaton background fields and potential fields, the inflationar y solutions for string cosmologies are obtained when the space-time dimensi on is D=3. It is found that the new cosmological solutions can be generated through O(d, d) duality transformations.
