摘　　要：介绍并讨论中日两国在世界上首次进行的，力值上限达２０ＭＮ的大力值国际比对。比对结果表明，两国大力值一致性的水平为：在６ＭＮ以下，保持在±３．０×１０－４以内；在６ＭＮ到２０ＭＮ范围，保持在±１．The method and results of the intercomparison of 20MN force standard machines between NIM of China and NRLM of Japan is described. The intercomparison of such large force standards had not yet been realized in the world. The uniformity of the force value of these two machines in the comparison is ±3.0×10 -4 in the range of not more than 6MN, and ±1.5×10 -4 in the range from 6MN to 20MN.
