中文摘要:

      介绍了一型自主研制的温控系统的原理与结构，采用核磁共振（NMR）实验测温方法检测了温控系统的精确性和稳定性.针对精确性进行了设计校正，校正后精确度达到了±0.2 ℃.指出了稳定性方面的特点与不足之处，提出改进意见.

英文摘要:

      The temperature control system is one of the important devices in an NMR spectrometer, its accuracy and stability play important roles in the resolution of the spectrometer. The temperature control system in a home-made NMR spectrometer has been tested and calibrated, showing an accuracy of ±0.2℃, and the characteristic and deficiency on the stability of the temperature control system has been described with suggestion of improvement.
