| 摘 要： | 红外谱图数据的精确拟合是建立标准谱图的重要组成部分,是光谱仪器正确进行定性和定量分析的基础.文章采用非均匀B样条对红外谱图数据进行曲线拟合,通过采用基于最大范数距离的B样条拟合算法,不仅解决了大容量红外谱图的精确拟合问题,同时对谱图峰值精确定位也提供了方便.文章介绍了非均匀B样条曲线,以及二阶(三阶)非均匀B样条曲线拟合的实现,重点描述了红外谱图数据拟合精度的控制方法.

| Abstract: | Accurate curve fitting of infrared spectrum data is important for building standard spectrum,and is the basic requirement for qualitative and quantitative spectral analysis.In the present paper,B-Spline was used to accurately fit the infrared spectrum data.Based on the max norm distances of B-Spline curve fitting arithmetic,this method not only resolved the curve fitting problem of infrared data,but also provided a convenient way to orient peak values of spectrum.The authors introduced the(B-Spline,) realized curve fitting of quadratic non-uniform B-Spline curves(for short: NUBSC),and described the precision control of curve fitting of infrared spectrum data. |
