摘要：

We find the exact general solution for cosmological models arising from the interaction of the gravitational field with two scalar fields in both Bat Robertson-Walker and the locally rotationally symmetric Bianchi I spacetime filled with an exponential potential. One scalar field self-interacts with this potential and the other is a free massless scalar field. The solutions have a singularity and a set of these exhibit the transition to power-law inflation for both metrics.
