摘　　要：The relationship between the dispersion capability and the temperature of argon arc plasma at 1 atm is deduced in view of the plasma＇s refractive index equation. The results indicate that argon arc plasma has a normal dispersion and its dispersion capability is nonlinear to the plasma＇s temperature in a wide range of temperature and wavelength region. According to the results of numerical calculation, the preferred optical methods are believed to be suitable for the diagnosis of argon arc plasma in different temperature regions.The relationship between the dispersion capability and the temperature of argon arc plasma at 1 atm is deduced in view of the plasma＇s refractive index equation.
