根据化探分析的任务和特点,建议用相对偏差计算公式及其控制图评价化探分析的精密度,应用t检验法和对子分析评价分析结果的正确度。化探分析结果的精确度用精密度和正确度两个指标来评价。
According to the mission and characteristics of geochemical exploration, it is suggested to use the relative deviation formula and its control chart to evaluate the precision of the geochemical exploration. The t-test and the sub-analysis are used to evaluate the accuracy of the analysis results. Geochemical analysis of the accuracy of the results with precision and accuracy of the two indicators to evaluate.
