期间核查在具体核查方法的制定和操作中,几乎都采用重复性测试作为唯一的核查手段,其缺陷较为明显,如对重复性好但已发生系统偏离的现象无法验证其异常,对变化趋势难以提前作出预测等,其适用性是有局限的。如何针对具体的标准及其是否存在合适的核查件,给出针对性的最佳核查方法,值得研究。特别是工作标准,多采用内部溯源的方式,其核查品质更易得到保证。本项目将以电学计量专业的多个参数为样本,进行核
Verification During the preparation and operation of specific verification methods, repetitive testing is almost always used as the sole verification means, and the defects are obvious. For example, the phenomenon that repeatability is good but system deviation has occurred can not verify the abnormality, To make predictions in advance, its applicability is limited. How to give specific criteria and whether there is an appropriate verification of the pieces, given the best verification method is worth studying. In particular, work standards, using more internal source approach, the verification of quality more easily be guaranteed. The project will be the electrical measurement of a number of professional parameters for the sample, the nuclear
