金属化学标准样品均匀性复检计算优化方案

Chemical Reference Materials of Metals for Chemical Analysis in Homogeneity Check Test and Their Optimal Calculating Solution

根据本所多年制作金属化学标准样品和用原子吸收光谱仪器进行各种标准样品均匀性复检的实际工作经验,对全国通用的该均匀性复检的统计数学模式所存在的问题从数理和实际运用上加以探讨.加了重要的模式计算的限定条件,编制了更合理优化的计算机程序.以使得各类化学和仪器的分析方法的标准样品的均匀性复检统计工作更准确可靠.

Based on the experience in preparation of chemical reference materials of metals for chemical analysis and in their homogeneity check test with flame atomic absorption spectrometric instruments. A discussion on the problems arising from the statistical - mathematical model universally used in China for the homogeneity test was made, and a more reasonable and optimized computer programme was devised by adding limited conditions for model computerization to accommodate methods of all kinds of chemical and instrumental ananlysis to make the homogeneity check test of the above mentioned chemical reference materials more accurate.
