摘要：
In this brief note we present a somewhat trivial result. Namely, we show that perturbative off-shell f(R)-theory is equivalent to Einstein gravity, as well as to the Brans-Dicke theory and the Einstein scalar field model. We also discuss possible generalization of this result to higher-order gravitational field models.
