摘要：
The purpose of this paper is to consider cosmological models that contain two scalar fields. One field is inflaton, the other is the source of the observed accelerated expansion of universe at the present time. For the model that is considered in this work the corresponding chiral cosmological model was found and the metric of the space of the internal field is defined.
