  Why is the low energy limit of type II superstring theory the ordinary supergravity theory

+ 2 like - 0 dislike

Is there a detailed explanation that the supergravity theory is the low energy limit of type II superstring theory? In polchinsky's <<string theory>> no such proof was given, although it mentioned that "one can calculate the string amplitude for both theory" and derived the form of type II A and B supergravity.
