基于对最小二乘 （CPA矩阵 ）法改进 ,提出CPA矩阵阻尼最小二乘算法 （DLS） ,在确定P系数矩阵对引入阻尼因子d从而降低了其病态程度对误差的敏感程度 将此法用于多组分复方药物分析如复方阿斯匹林片剂测定 ,操作简便 平均回收率 99 6 %～ 10 1 1% （± 0 51～ 0 4 ） %

Based on improving least square method by CPA matrix, CPA matrix damp least square (DLS) method has been established, optimized the P coefficient matrix and damp factor d, the sensitivity of deviation from morbid degree will be decreased. Using this method determination of multi-constitute in combination Aspirin tablet, the operation is simple and convenient. Th...
