摘　　要：在类氢离子能级相对论修正的基础上,依据屏蔽方法,给出了类氟体系基态电离能的一种表达式.依据原子序数9至20的元素类氟体系基态电离能的实验数据,使用Microcal Origin软件拟合出类氟体系非电离电子平均屏蔽系数与原子序数的函数关系,总结出类氟体系基态电离能遵从的关系式并进行了验证.推算了原子序数21至40的元素类氟离子的基态电离能.Based on an amendment of ionization potential in hydrogen-like ions by the theory of relativity,the expression of ionization energy of florin-like system is given using shielding method.Based on the experimental data of ionization energy of florin-like system from Z=9 to 20,the function of shielding coefficient of florin-like ions and atomic number is summarized using software of Microcal Origin.A regular pattern of ionization energy of ground states of florin-like ions is given.The ionization energy of florin-like system from Z=21 to 40 is also calculated.
