玻恩-因菲尔德理论是麦克斯韦电动力学的非线性推广。它自然是作为开放弦的低能有效作用而产生的，也是d膜的世界体积有效作用的一部分。Born-Infeld作用的N=1和N=2超对称推广与刚性扩展超对称的部分自发破缺密切相关。我们回顾了Born-Infeld作用的一些显著特征，并概述了它在四维上的超对称推广。在超空间中给出了玻恩-因菲尔德理论的非阿贝尔N=1超对称推广及其N=1超引力元。
Born-Infeld theory is the non-linear generalization of Maxwell electrodynamics. It naturally arises as the low-energy effective action of open strings, and it is also part of the world-volume effective action of D-branes. The N=1 and N=2 supersymmetric generalizations of the Born-Infeld action are closely related to partial spontaneous breaking of rigid extended supersymmetry. We review some remarkable features of the Born-Infeld action and outline its supersymmetric generalizations in four dimensions. The non-abelian N=1 supersymmetric extension of the Born-Infeld theory and its N=1 supergravitational avatars are given in superspace.
