【摘要】 由于纯水独特的吸光度光谱特性,常见的定量分析方法对水溶液的吸光度光谱进行定量分析时,效果并不理想,误差较大,稳定性不高.在迭代最小二乘算法的基础上,结合连续小波变换理论,提出了一种改进的处理水溶液定量分析问题的算法.该算法利用了连续小波变换多尺度提高光谱的分辨率的特性,有效地提高了利用物质的吸光度光谱,对水溶液定量分析问题时的精度和稳定性问题.更多还原

【Abstract】 Due to the unique spectral characteristics of the pure water,common quantitative analysis methods to aqueous solution are not satisfying.And these methods result in obvious error and low stability.This paper introduces an algorithm,based on the iterative least square method and combining the continuous wavelet transform theory.It uses the advantages of CWT which improves the spectral resolution through by multiscale analysis.And this algorithm improves precision and stabilization of the quantitative analysis of the pure water effectively.更多还原
