【Abstract】 At Sep, 2003, the four calibration laboratories made the experiment of AH2500A capacitance bridge. It obtained the very valuable comparison data. The data will be published here, and the data will be analyzed in this article. We put forward the suppose that the four capacitance bridges, as a group, can check the stability each other, and can get trace ability by indirect method. As an example, the one of the group traces to higher level standard, and then, the others will be calibrated by comparison data. The experiment data are share by four labs above.更多还原
