根据Erler和Maccaferri最近提出的方法，我们构造了描述恒定磁场背景的Witten三次弦场理论的运动方程的解。研究了与此背景相关的边界条件变换算子，并计算了它们的算子积展开式。我们得到了经典作用与玻恩-因菲尔德作用重合的解。
Following the method recently proposed by Erler and Maccaferri, we construct solutions to the equation of motion of Witten's cubic string field theory, which describe a constant magnetic field background. We study the boundary condition changing operators relevant to such a background, and calculate their operator product expansions. We obtain solutions whose classical action coincide with the Born–Infeld action.
