摘要：
According to the analytical form of Voigt line shape function, the empirical formula of Voigt line shape width and Lorentz line shape width and Gaussian line shape width is established by numerical calculation method. Based on the empirical formula of line shape width, the calculation scheme of Lorentz and Gaussian width obtained by experimentally spectral line shape width is established. The reliability of our calculation scheme is verified by a set of line shape functions. According to the method established in this work, the 696.5 nm line of the Ar gas plasma jet is calculated, and the corresponding Lorentz line shape and Gaussian line shape function are obtained. © 2019, Science Press.
