摘要：

The cosmological equations of a gravitational field, minimally coupled witha scalar field, are exactly integrated, provided that the potential of the scalar field belongs to a special class of exponentials. A particular solution is given, exhibiting the damping of the effective cosmological constant and a power-law inflation. © 1990.
