这种设计方法不仅对于单片轴向梯度折射率透镜，而且对于同时包括均匀介质元件的光学系统也是很方便的。

The use of the method is not limited to simple lenses with gradient indices. It can also be used conveniently in the design of systems having homogeneous-medium elements.

结果表明，轴向折射率梯度在一定条件下可以补偿径向折射率梯度的影响。

Results show that the axial index gradient can compensate the effect caused by radial index gradient in some cases.
