Well, we have to figure out how to set up our triple integral in spherical coordinates.
先看看怎么，在球坐标中建立三重积分。

In his new paper, Dokuchaev has looked at stable circular orbits as well as spherical, non-equatorial orbits for photons at the inner boundary.
在Dokuchaev的这篇新论文里，他既考虑了光子在内边界的稳定圆轨道，也考虑了球形非赤道面轨道。

The electronic states were investigated by a model of the spherical square well with infinite depth and the radii of the quantum dots were estimated from the parameters of luminescence data.
