In our own solar system, Mars shows evidence of extreme climate change, the result, scientists believe, of a rotational tilt that flips between zero and 60 degrees over time.

在我们自己的太阳系，火星上极端变化的气候表明了是由于它的旋转倾角随时间在0到60度之间的变化而引起的。

Data transfer times are typically fractions of a millisecond, so rotational latency and seek time are the primary sources of disk latency on a physical HDD.

数据传输时间一般几毫秒，所以旋转延迟时间和寻道时间是一个物理hdd的主要磁盘延迟时间来源。

Needless to say that huge amount of rotational kinetic energy must be stored in planets and in stars, and I would like to spend quite some time on that.

不用说，这巨大的，旋转动能，肯定储藏在行星中，我要多花些时间，来讲这个。

Experts say that while rotational grazing can save money over time, it also requires planning.
