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

8字曲线的宽度正体现了这种偏离的程度。

Just how the analemma appears depends upon where you are.

这个8字形状对于各地的人来说不完全相同。

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.

地球仪上曾印有行迹，以便人们根据算时钟时间与太阳时间之间的差异。

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.

因此， 地球的轴倾斜部分解释了为何太阳在天空中的位置会发生变化，而行迹的长度则代表了太阳全年赤纬变化的完整46.8度范围。
