摘　　要：由于传统的校验计量资质不能涵盖纳米级低时延通信仪表校准的能力,因此要通过一定的方法来确定新形仪表的准确率。首先,通过线性回归的方法对仪表的内在参数进行了点估计;然后,对参数的取值区间进行了估计;最后,按照仪表校验的要求对仪表的不确定度进行了评估。通过将仪表精度参数的计算结果运用在实际测试中,并加上不确定度的范围,得到了完备的测试结果。然后,将点估计的参数和理论计算的结果进行比较,证明了这样的校准过程结果是准确可信的。提出的方法是一种通用的方法,在测试过程中,遇到校准计量能力无法覆盖的仪表时,特别是结果和测试参数有线性关系时,可以按照这样的思路设计校准实验。Since the traditional calibration measurement qualification can not cover the calibration ability of nanoscale low-delay communication instrument,it is necessary to determine the accuracy rate of the new instrument by certain methods.Firstly,the internal parameters of instrument are estimated by linear regression.Then,the value interval of the parameters is estimated.Finally,the uncertainty of the instruments is evaluated according to the requirements of the instrument calibration.By applying the calculation results of the instrument precision parameters to the actual test,and adding the range of uncertainty,the complete test results are obtained.And the results of the calibration process are proved to be accurate and reliable by comparing the parameters of the point estimation with the results of theoretical caloulation.The proposed method is a general method.In the process of testing,when encountering the instrument that cannot be covered by the calibration capability,especially when the result is wired to the test parameter,the calibration experiment can be designed according to this idea.
