为进行大规模核天体网络运算，通常将核天体物理反应率拟合为与温度相关的数值表达式，以简化程序中的核物理输入量。通过分析国际上常用的几种核天体物理数据库，本工作得到了一种新的拟合方法，其对反应率的拟合精度较目前国际上通用的 REACLIB和 NACRE 数据库的拟合方法的有明显改善。该拟合方法适用于直接反应和窄共振、宽共振、阈下共振和多谐共振反应，方便建立核天体物理反应率数据库。

In large-scale nuclear astrophysics network computing,the nuclear astrophys-ics reaction rates were usually fitted to numerical reaction rates concerning temperature in order to reduce the input nuclear parameters.By analyzing the existing databases adopted internationally,a new fitting method was present in this paper,which can give much better fitting results than REACLIB and NACRE.This new fitting method can be applicable to direct reaction rates,isolated and narrow resonance reaction rates,multi-resonant reaction rates,subthreshold states and broad low energy resonances reaction rates,and is convenient to build nuclear astrophysics reaction rate data library.
