摘 要：干井式溫度校驗器被廣泛應用于企業現場和計量實驗室，為了評估其性能，就需要計量機構對干井式溫度校驗器進行校準。但目前我國還沒有制訂其校準的相關標準和規范。現根據干井式溫度校驗器的性能特點、測溫原理和使用范圍，參考國際上采用的校準指南對干井式溫度校驗器的校準方法進行了研究，主要內容包括溫度偏差、溫度穩定性、溫度均勻性、散熱效應和負載影響，并通過校準實例說明該校準方法是切實可行的。
關鍵詞：干井式溫度校驗器；校準；校準方法；溫度偏差；溫度穩定性；溫度均勻性

Abstract： Dry-well temperature calibrator is extensive used on the scene of enterprise and the metrological laboratory, In order to evaluate its performance, metrological organization needs to carry on the calibration to dry-well temperature calibrator. However at present, our country has not worked out a relevant standards and norm to calibration of dry-well temperature calibrator. The paper based on the function characteristic, temperature measuring principle and range of dry-well temperature calibrator and adooted reference of the international guide in the research of calibration method. The main content included temperature deviation, temperature Stability, temperature Uniformity, stem conduction and loading effect. Experiment shows that the calibration method is practical and feasible
Key words： Dry-well temperature calibrator; Calibration; Calibration method; Temperature deviation; Temperature Stability; Temperature uniformity
