在Witten的三次弦场理论中，通过积分出所有的质量场，计算了玻色子开弦的无质量场的树级有效作用的前导项。在阿贝尔理论和非阿贝尔理论中，场的重新定义使得用常规场强来表示有效作用成为可能。由此产生的行为再现了阿贝尔和非阿贝尔玻恩-因菲尔德理论中的主要术语。原则上，该方法可用于系统地确定阿贝尔和非阿贝尔动作中的所有项，包括所有高阶导数项。
The leading terms in the tree-level effective action for the massless fields of the bosonic open string are calculated by integrating out all massive fields in Witten's cubic string field theory. In both the abelian and nonabelian theories, field redefinitions make it possible to express the effective action in terms of the conventional field strength. The resulting actions reproduce the leading terms in the abelian and nonabelian Born-Infeld theories. In principle this method can be used to systematically determine all terms in the abelian and nonabelian actions, including all higher-order derivative terms.
