摘　　要：该文阐述了测压铜柱、铜球的动态误差形成原因、准动态校准方法消除其动态误差的机理及压力准动态校准设备的原理和方案 ,对其不确定度作了说明 ,最后对建立铜柱、铜球准动态校准的最高国防基准应深入研究的问题进行了讨论。The formation cause of dynamic error for pressure-measuring copper cylinder and copper ball is clarified in the paper. The mechanism of eliminating dynamic error by means of quasi-dynamic calibration is analysed, and the principle and the designing of quasi-dynamic calibration system are also presented. Accordingly, the indeterminacy is also explained. The problems that the upmost national defence benchmark of quasi-dynamic calibration for copper cylinder and copper ball must be studied deeply are discussed.
