我们证明了对于一大类基于拉格朗日的扭转理论，宏观陀螺仪对扭转场是不敏感的：不可能存在扭矩与陀螺仪的旋转角动量的耦合。为了探测扭转，需要一个具有净基本粒子自旋的偏振系统。这些结论从构成推导运动方程的基础的守恒定律中可见一斑。
We demonstrate that for a large class of Lagrangian-based torsion theories a macroscopic gyroscope is insensitive to the torsion field: There can be no coupling of the torsion to the gyroscope's angular momentum of rotation. To detect torsion a polarized system with a net elementary particle spin is needed. These conclusions are evident from the conservation laws, which form the basis for deriving the equations of motion.
