摘　　要：通过对选定的核查标准的测量，利用被核查标准的最大允许误差和校准证书给出的校准结果及其不确定度，来确定核查测量控制图的“中心线”、上下控制界限和警戒线，利用Excel电子表格绘出这些控制界限，使每次核查测量结果在图中直观准确地反映被核查标准的误差或量值的变化方向和大小。该结果也可作为计量标准稳定性考核的依据。Through the measurement of selected check standard, using the maximum permissible errors and calibration certificate given calibration results and its uncertainty of the standard which to be check, to determine the ＂center line ＂ , the upper and lower control limits and warning line of the check measurement control chart. Using the Excel spreadsheet to draw the control limit, to make each check measurements in figure intuitive accurately reflect the error or the value change of direction and size of the standard which to be check. The results can also be used as the basis for assessment of stability for t standard.
