摘　　要：在膨胀式真空标准装置上对同一支磁悬浮转子规进行了连续5个校准周期的校准,通过对校准数据的分析,以及对磁悬浮转子规的长期稳定性等计量特性的研究,从而确保磁悬浮转子规在量传过程中数据的准确、可靠。One spinning rotor gauge was calibrated against the static expansion vacuum standard, over five periods continuously. The metrological characteristic of spinning rotor gauge, such as long-term ：stability was investigated by analyzing calibration data. Accordingly, insure the measured values put up accurately and credibly through transfer course.
