In the context of a gauge theory for the translation group, a conserved energy-momentum gauge current for the gravitational field is obtained. It is a true spacetime and gauge tensor, and transforms covariantly under global Lorentz transformations. By rewriting the gauge gravitational field equation in a purely spacetime form, it becomes the teleparallel equivalent of Einstein's equation, and the gauge current reduces to the Moller's canonical energy-momentum density of the gravitational field.
在平移群规范理论的背景下,得到了引力场的一个守恒能量 - 动量规范流。它是一个真正的时空和规范张量,并且在整体洛伦兹变换下协变变换。通过将规范引力场方程重写为纯时空形式,它成为爱因斯坦方程的遥平行等效形式,并且规范流简化为引力场的莫勒正则能量 - 动量密度。
