In this work we propose a criterion to apply the Abel inversion in the case of a small set of experimental data to be used in laboratory plasmas. The Nestor-Olsen method, spline interpolation, and Fourier transform Abel inversion have been compared in order to study the influence of statistical noise and the number of sampled data. The application of this criterion permits us to obtain a radial distribution of the plasma parameters (densities and temperatures) from the spectral line profiles emitted by the discharge. The proposed criterion has been tested using the lateral intensities of several lines emitted by a microwave helium plasma column generated at atmospheric pressure.
在这项工作中，我们提出了一种准则，用于在实验室等离子体中使用少量实验数据的情况下应用阿贝尔反演。为了研究统计噪声和采样数据数量的影响，我们对内斯特 - 奥尔森方法、样条插值法和傅里叶变换阿贝尔反演进行了比较。应用该准则使我们能够从放电发射的光谱线轮廓中获得等离子体参数（密度和温度）的径向分布。我们使用在大气压下产生的微波氦等离子体柱发射的几条谱线的横向强度对所提出的准则进行了测试。
