为辨别环境动态变化而进行的多期次环境地球化学填图要求降低不同期次数据间的分析误差。为达此目的,本文提出了衡量各实验室分析质量的新的考核标准,包括:一组标准样不同元素分析值与标准值对数偏差的不合格率;一组标准样不同元素分析值与标准值的相关系数所反映的相似性系数;一组标准样各种元素分析值与标准值在虚拟空间上图形分布的相似性。
Multi-stage geo-chemical mapping in order to identify the dynamic changes of the environment is required to reduce the analysis error between different periods of data. In order to achieve this goal, this paper proposed a new assessment standard to measure the quality of each laboratory, including: the failure rate of logarithmic deviation between the values of different elements in a set of standard samples and the standard values; The similarity coefficient reflected by the correlation coefficient of the standard value; the similarity of the graphical distribution of each elemental analysis value and the standard value of a set of standard samples in the virtual space.
