我们揭示了为什么偶然的平坦性约束出现在协变圈量子引力的振幅的某些限制的原因。我们展示了为什么这种约束是无害的，显示如何类似的偶然约束出现在过渡振幅的简单系统，当某些限制被认为是。
We shed some light on the reason why the accidental flatness constraint appears in certain limits of the amplitudes of covariant loop quantum gravity. We show why this constraint is harmless, by displaying how analogous accidental constraints appear in transition amplitudes of simple systems, when certain limits are considered.
