It is shown that the characteristics of the farfielddistribution is substantially improved.
结果表明，其远场分布特性均有本质的改进。

In this paper, when assuming a Gaussian near fielddistribution on the cross section of single-mode fiber, it has been derived theoretically that the farfield is also a Gaussian distribution.
本文在假定单模光纤横端面上的近场为高斯分布的前提下，从理论上导出了其远场分布也是高斯分布。
