The analemma's width represents the extent of this deviation.

8字曲的宽度正体现了这种偏离的程度。

Oddly enough, it makes this figure eight pattern, known as the Sun's analemma, but why?

让吃惊的是，太阳的轨迹形状是一个“8”这也被称作“地球仪8字曲”但是为什么会如此呢？

Just how the analemma appears depends upon where you are.

这个8字形状对于各地的来说不完全相同。

Globes even used to have the analemma printed on them to allow people to determine the difference between clock time and solar time based on the day of the year.

曾经的地球仪上面还会印上8字曲，们能知道钟表时间和太阳时间的差距。

So the Earth's axial tilt partially explains why the Sun changes positions in the sky and the analemma's length represents the full 46.8 degrees of the sun's declination throughout the year.

所以地球的自转轴的倾斜能够部分解释太阳在天空中位置变化的原因，地球仪的8字曲的长度也代表了太阳在一整年倾斜的46.8°的角度。
