标准砝码是三点测力式质心台标定校准的专用计量设备，其质量计量的准确性直接关系到质心台的测量精度。通过对质心台标定算法的分析，得出标准砝码的计量误差会影响质心台的标定系数，从而影响质心台测量精度的结论，根据分析结果提出了相应的修正方法，并在实际应用中验证了方法的有效性。%The standard weight is a special equipment for the calibration of the three-load center of gravity (COG) table. The calibration algorithm of the COG table is analyzed. The results show that the error in the weights affects the calibration coefficients, thus will affect the measurement accuracy of COG table. And the influence of the errors can be eliminated by a theoretical calculation in practical application.
