摘要：
We determine how the usual formula for density perturbations from inflationary cosmology should be modified when the inflaton is coupled to the scalar curvature at the level of the Lagrangian. By applying a conformal transformation to a single gauge invariant quantity, we rederive a previously proposed formula for the fully coupled system in a simple and unambiguous way.
