本文考虑了施瓦茨和Sen [J.H.施瓦茨和A. Sen，B 411（1994）35]。它是基于扩大的模型与动力学矢量场是一个时间的局部洛伦兹框架的分量。这使得我们可以在平坦时空中保持模型的明显洛伦兹不变性。这个场的存在被认为是引力相互作用的遗迹，引力相互作用尊重弯曲时空中的一般坐标不变性，但打破了切空间中的局部洛伦兹对称性。
We consider a generalization of a duality symmetric model proposed by Schwarz and Sen [J.H. Schwarz and A. Sen, Nucl. Phys. B 411 (1994) 35]. It is based on enlarging the model with a dynamical vector field being a time-like component of a local Lorentz frame. This allows one to preserve the manifest Lorentz invariance of the model in flat space-time. The presence of this field is regarded as a relic of gravitational interaction which respects the general coordinate invariance in curved space-time but breaks the local Lorentz symmetry in tangent space down to its spacial subgroup.
