Taking the circular fibres for the example, the firstordercorrection local field and field shift in the fundamental mode peak field are discussed.
以圆光纤为例,讨论了一阶近似本地场形式及基模场在最大值处的场位移。

In fact, this method is improper. The mistake results mainly from the following hypothesis: the firstordercorrection of the heat conduction equation is tenable for all parameters in physics.
The first step requires cutting the claw of the claw, the purpose is to establish a good benchmark, in order to improve the accuracy of the correction, this step is best not to save.
