1、I mean usually you will switch to polar coordinates either because the region is easier to set up.
通常你轉(zhuǎn)換到極坐標系下，有可能積分區(qū)域更容易建立。

2、So the idea of spherical coordinate is you're going to polar coordinates again in the rz plane.
所以說球坐標系,其實就是在rz平面再建立一個極坐標。

3、That's in line with the idea that we are just doing again, polar coordinates in the rz directions.
球坐標中的平面也差不多是這樣了，只要把rz看做極坐標就行了。

4、But still we could set this up and then switch to polar coordinates to evaluate this integral.
但還是可以建立這個積分，然后轉(zhuǎn)換到極坐標系下去求結果。

5、In terms of the Schrodinger equation, we now can write it in terms of our polar coordinates here.
在薛定諤方程中，我們現(xiàn)在可以用，極坐標的方式來表示了。
