摘要：

A derivation of N = 1 supergravity action from string theory is presented. Starting from a Nambu-Goto bosonic string, matter field is introduced to obtain a superstring in four dimensions. The excitation quanta of this string contain graviton and the gravitino. Using the principle of equivalence, the action in curved space-time are found and the sum of them is the Deser-Zumino N = 1 supergravity action. The energy tensor is Lorentz invariant due to supersymmetry.
