摘要
将小波与偏最小二乘光度法相结合，对地质样品相态分析中多种相态组分进行同时测定，提高分析信号的信噪比，使计算结果的精度得到提高。应用于珲春金铜矿中铜的相态分析，结果令人满意。明显优于一般ＰＬＳ方法。并对小波变换的去噪机制和小波变换的参数选择进行了讨论。
The multiphases in the geological samples are analysized by wavelet -- partial leastsquares spectrophotometry method, which was combined with wavelet and partial--least--squares. Thesignal/noise ratio and the precision of the results are improved. The results of the phase analysis on gold--copper ore from Hunchun are acceptable. And then the principle fundamentals of filter and optimization of parameters about the wavelet transform were introduced.
