摘要：

Nonperturbative effects of instantonlike solutions are studied within the framework of supergravity theories with field-dependent gauge functions. Fermionic zero modes are constructed and some typical correlation functions are evaluated. The effects of instantons are very similar to those in globally supersymmetric theories: they preserve supersymmetry while breaking a chiral U(1) symmetry. Nonperturbative amplitudes receive corrections which are suppressed at large distances.
