在四维N = 1超重力中构造了一个耦合于二形式场的Dirac-Born-Infeld （DBI）作用。我们的作用的超共形公式显示了在各种庞加莱超引力公式中构造它的通用方法。我们将DBI动作推广到与物质扇区相关联的动作。我们还讨论了DBI作用的对偶变换，这对于现象学和宇宙学的应用是有用的
: We construct a Dirac-Born-Infeld (DBI) action coupled to a two-form field in four dimensional N = 1 supergravity. Our superconformal formulation of the action shows a universal way to construct it in various Poincar´e supergravity formulations. We generalize the DBI action to that coupled to matter sector. We also discuss duality transformations of the DBI action, which are useful for phenomenological and cosmological applications
