摘　　要：R矩阵理论是研究天体核反应的重要理论工具。为实现相关的数学计算,开发了多种基于此理论的程序,其中的DREAM程序使用了可视化的Basic宏来实现对R矩阵理论的计算,AZURE2程序则是一款利用C++编程语言制作的界面友好、实用性很强的R矩阵拟合工具。为验证不同R矩阵工具的拟合结果,利用DREAM和AZURE2分别对12C(p,p)12C和21Na(p,p)21Na共振散射实验数据进行了拟合,并对拟合的各项参数进行了对比。对比的结果显示出两种工具的符合情况很好,可达到互相验证的目的。The R-matrix theory is very important in the study of astrophysically nuclear reactions.Many codes have been written to implement the mathematics based on this theory.DREAM code makes use of visual Basic macros.AZURE2 code,a more improved user interface tool has recently become available using C++program.In order to check the fits of different R-matrix tools,DREAM and AZURE2 codes were applied to the data of 12C(p,p)12C and 21Na(p,p)21Na,respectively.The extracted parameters were compared.These two codes are shown to be broadly consistent and can be used to cross-check each other.
