摘要：
New classes of classically integrable models in the cosmological theories with a scalar field are obtained by using the freedoms of defining time and fields. In particular, some models with the sum of exponential potentials in the flat spatial metric are shown to be integrable. The model with the sine-Gordon potential can be solved in terms of analytic continuation of the nonperiodic Toda field theory.
