实验结果与真值(或约定真值)之间的一致性是采用重复性和复现性来表征的,为合理评定重复性和复现性,常采用比对实验。比对实验的目的是验证参加比对实验的各检测实验室的测试结果的可比性,检查评价各检测机构的综合检测技术能力和水平。
The agreement between experimental results and true values (or agreed truth values) is characterized by repeatability and reproducibility. To make a reasonable assessment of repeatability and reproducibility, comparison experiments are often used. The purpose of the comparison experiment is to verify the comparability of the test results among the testing laboratories participating in the comparison experiment and to check and evaluate the capability and level of the comprehensive testing technique of each testing organization.
