等离子体的温度测量与光谱测温仪

Temperature Measurement of Plasma and a Spectroscopic Pyrometer

论述了基于光谱学原理的温度测量技术．介绍了在上述原理下建立起来的光谱 测温仪。该仪器能测量符合局域热力学平衡与柱对称条件的电弧及高频等离子体的温度 剖面。测温范围为 ５ ０００—１５ ０００ Ｋ，不确定度约 ２．２％。

Temperature measurement technique based on the principles of optical spectroscopy was discussed and the spectroscopic pyrometer developed thereunder was presented. Temperature distribution in arc or RF plasma torch which conform to local thermodynamic equilibrium and axis--symmetry can be obtained with this pyrometer. The measurement range is 5000~15000 K and the uncertainty of measurement is 2.2 %.
