| 摘 要： | 本文发展了测量散射体温度的拉曼光谱方法，选用Ｓｒ（ＮＯ３）２粉晶做散射介质，观察到７３８ｃｍ＾－１，１０５７ｃｍ＾－１两个拉曼散射带，记录它们的Ｓｔｏｋｅｓ、Ａｎｔｉ－Ｓｔｏｋｅｓ分量的光谱强度，得到硝酸锶粉晶散射体的温度。实验结果显示，这种非接触光谱测温法具有重要的实用价值。

| Abstract: | We have developed a new method for the determination of temperature with Raman scattering spectra. The strontium nitrate was chosen as an experiment substance. It has two bands of Raman scattering, and their wavenumbers are 738 and 1,057 cm-1 in 600-1,700 cm-1. We have obtained the intensities of their Stokes and Anti-Stokes scattering, then we have got two temperatures of strontium nitrate according to the formula. The result from the 738 cm-1 scattering band has larger error than that from the 1,057 cm-1. This may account for the noise of the photocounter. This no touch method is fit to measure the temperature of the molecular. |
