这就意味着，如果你身处南极或北极附近，你离地心的距离就比在赤道更近一些——纬度的测量就与地心有关。
This means that near the north or South Pole you are actually closer to the centre of the earth-where the Angle is being measured from-than you would be at the equator.

大地纬度的解算是从地心直角坐标到大地坐标变换的关键，通常都用采用迭代法实现。
The computing of latitude is the key of geodetic coordinate transformation from geocentric coordinate which conventionally USES iterative methods.

好了，现在看清楚了：在这个地球切面上，我们深入地心的这把光剑和赤道线的夹角就是我们的纬度啊！
Now it becomes clearer: on this plane, the angle between the light from the light saber and the Equator is our latitude!
