基于黑体辐射原理的简易温度测量仪

摘要

利用维恩位移定理及光栅的分光原理，制作了简易的温度测量仪。利用此测量仪测量了太阳表面的温度为5794 K ，实验结果与太阳表面的理论温度5692 K基本一致。%Based on the Wien displacement law and the principle of grating ,a simple thermometer was manufactured .It had the advantages of simple structure ,low cost and good accuracy .Finally , the temperature of the sun was measured by this simple thermometer ,and the results agreed well with the theoretical results .
