Motivated by the standard form of string-theory amplitude, we calculate thefield-theory amplitude to complete the higher-derivative terms in type IIsupergravity theories in their conventional form. We derive explicitly the $O(\alpha'^3) $ interactions for the RR (Ramond-Ramond) fields with graviton,B-field and dilaton in the low-energy effective action of type II superstrings.We check our results by comparison with previous works that have been done bythe other methods, and find an exact agreement.
