我们在一个简单的D = 10的背景中导出了IIA型超弦的完全协变作用量，该背景代表一个具有磁性Ramond-Ramond向量场的7-膜（并且是Kaluza-Klein Melvin解的U-对偶）。这个弯曲的背景可以从一个平坦的（但拓扑上非平凡的）D = 11的时空降维得到。超膜在这个平坦的D = 11空间中传播的行为很容易写下来。通过对超膜作用量进行双维约化，得到了超弦作用量的显式形式。在光锥规范中，作用量只包含费米子中的二次项和四次项。
We derive the complete covariant action for the type IIA superstring in a simple D = 10 background which represents a 7-brane with a magnetic Ramond-Ramond vector field (and is U-dual to the Kaluza-Klein Melvin solution). This curved background can be obtained by dimensional reduction from a flat (but topologically non-trivial) D = 11 space-time. The action of a supermembrane propagating in this flat D = 11 space is straightforward to write down. The explicit form of the superstring action is then obtained by double dimensional reduction of the supermembrane action. In the light-cone gauge the action contains only quadratic and quartic terms in fermions.
