After compensation the eye diagrams can be well recovered both for NRZ and RZ formats.

不论对于非归零码还是归零码，补偿后眼图恢复很好。

That's in line with the idea that we are just doing again, polar coordinates in the rz directions.

球坐标中的平面也差不多是这样了，只要把rz看做极坐标就行了。

So the idea of spherical coordinate is you're going to polar coordinates again in the rz plane.

所以说球坐标系,其实就是在rz平面再建立一个极坐标。
