摘要
给出了以恒定角速度旋转的圆盘的广义相对论描述。论证了从概念上讲，这种直接方法比狭义相对论方法问题更少。对于圆盘上的观察者，其固有空间的几何是双曲的。这对他们解释具有相同半径的非旋转圆盘的几何有有趣的影响。讨论了时钟同步对空间测量的影响。

10 pages, 3 figures, this is the version accepted by American Journal of Physics; I had to remove the special relativity part, which one of the referees did not like; it is still available in v1
