摘要：

The scalar field driving inflation in a general Robertson-Walker cosmology is used as a dynamical variable to express the field equations as a first-order differential system. This allows a study of super-inflation to be made. It is found that super-inflation is likely to occur in closed cosmologies when the slow-roll approximation is valid and a new super-inflationary solution is presented. The possibility of extending this technique to the Bianchi models is examined.
