本文提出了一个局部超对称大统一程序，它将N= 1的超引力多重态耦合到一个具有任意数量左手手征多重态和一个规范矢量多重态的大统一规范群上。我们讨论了一个特殊的模型，它表明引力相互作用不仅消除了在全局超对称性中遇到的真空态的简并性，而且同时它们可以打破超对称性和SU（2）<$U（1），使其在300 GeV处成为剩余的SU（3）c <$U（1）对称性。
A locally supersymmetric grand unification program is proposed which couples the N= 1 supergravity multiplet to an arbitrary grand unified gauge group with any number of left-handed chiral multiplets and a gauge vector multiplet. A specific model is discussed where it is shown that not only do the gravitational interactions eliminate the degeneracy of the vacuum state encountered in global supersymmetry, but simultaneously they can break both supersymmetry and SU (2)⊗ U (1) down to a residual SU (3) c⊗ U (1) symmetry at∼ 300 GeV.
