摘要
解析扩展Ｘ射线吸收精细结构谱（ＴｈｅＥｘｔｅｎｄｅｄＸ－ｒａｙＡｂｓｏｒｐｔｉｏｎＦｉｎｅＳｔｒｕｃｔｕｒｅ，ＥＸＡＦＳ）的一种方法是曲线拟合．在曲线拟合中，能量阈值Ｅ０的确定有着很重要的意义，同时也有相当的难度．本文应用ＡＫＩＭＡ平滑数据点方法达到了对Ｅ０在数学意义上的精确求解．数据分析结果表明，这种方法的处理结果是令人满意的．
One method of data analysis of the Extended X-ray Absorption Fine Structure(EXAFS) is curve fitting. In this Process. importance of the threshold energy Eo is emphasized for its resulting in speed and quality of curve fittiug. AKIMA method which can be used to smooth data was performed to obtain Eo(mathmatically speaking) in our paper. and the satisfying result could be seen after the discussing.
