| 中文摘要: |
| 通过模拟电阻的有关原理阐述，提出对模拟电阻的校准，不仅要考虑激励电流大小的影响，也要考虑激励电流方向的影响。提出了针对不同等级的模拟电阻采用不同的校准设备，以提高工作效率。对模拟电阻校准进行了GUM法和MCM法测量不确定度评定，评定结果基本一致，说明测量不确定度评定合理。通过对测量不确定度的验证，证明校准方法的可行性和实用性。 |
| 英文摘要: |
| The principles of analog resistance are elaborated and suggestions are put forward that the effects of both excitation current magnitude and excitation current direction should be considered for calibrating the analogresistance. Different grades of analog resistance should be calibrated by different devices to improve work efficiency. The GUM method and MCM method are used in evaluating the measurement uncertainty of analog resistance calibration. The evaluation results are basically identical, proving that the evaluation of measurement uncertainty is reasonable. The verification of the measurement uncertainty demonstrates the feasibility and practicability of the calibration method. |
