摘要
上海天文台的氢原子钟从1991年起采用了热敏电阻控温的新恒温系统，这种方法具有灵敏度高、控温精度高和重复性好的特点。本文简要介绍这种方法的原理、工作情况和结果，并讨论了某些相关的问题。
Since 1991 year, the thermistor is used for thermerls control system on the Hydrogen clock at Shanghai Observatory. This method is sensitiver and stabler than original method and the temperature reproducibility is better than latter also- In this paper, the fundamental principle and some results are intruduced, and some relative questions are discussecl also.
