论文摘要
从重力电信磁性的角度来检查弗里德曼 - 罗马 - 罗伯逊 - 罗伯逊步行者的宇宙学，与哈勃半径相比，时空区域的近似值很小。通常的Lorentz仪表不适合这种情况，而Painlevé-Gullstrand仪表很自然。讨论了几种非平凡的特征和差异在“标准”渐近平坦的重力电磁作用中。
Friedmann-Lemaître-Robertson-Walker cosmology is examined from the point of view of gravitoelectromagnetism, in the approximation of spacetime regions small in comparison with the Hubble radius. The usual Lorentz gauge is not appropriate for this situation, while the Painlevé-Gullstrand gauge is rather natural. Several non-trivial features and differences with respect to "standard" asymptotically flat gravitoelectromagnetism are discussed.
