摘要：

We consider the minisuperspace model arising from the lowest-order string effective action containing the graviton and the dilaton and study solutions of the resulting Wheeler-DeWitt equation. We discuss the role of the scale-factor duality symmetry in the context of our quantum cosmological model.
