hankel function of the second kind meaning in Chinese

第二类汉克尔函数

The fma need the high order hankel function , in chapter 3 the algorithm of calculating the high order hankel function of the second kind is discussed . because of the low effectivity and unsteadiness to use the recursive algorithm to calculate the high order hankel function of the second kind , the paper introduces a kind of new fast algorithm to solve the problem . the worked result indicates : the new fast algorithm is a kind of precise algorithm
由于快速多极子法计算中要用到高阶汉克尔函数，在第三章中，主要针对利用递推算法求解高阶汉克尔函数时速度较慢和可能存在不稳定的问题，给出一种快速计算高阶汉克尔函数方法，最后给出了用快速多极子法计算的四个导体柱体散射截面。
