讨论了斯塔克等离子体光谱的研究现状。考虑了电场和相关等离子体参数测量的可能性。简要介绍了线性和非线性斯塔克效应的理论。对不同性质的电场——相关的外部静态场和交替场、等离子体湍流场、带电粒子产生的微场——描述了斯塔克效应的具体特征——位移、分裂和相关的谱线展宽、禁止跃迁。考虑了基于经典发射光谱的技术，以及新的线性和非线性激光技术。结果表明，新发展的相干激光光谱方法的应用从根本上提高了高压范围内电场测量的可能性。
The present state of Stark plasma spectroscopy is discussed. The possibilities of measurements of electric field and related plasma parameters are considered. A brief theory of linear and nonlinear Stark effect is outlined. The specific features of Stark effect — shifts, splitting and related line broadening, forbidden transitions — are described for the electric fields of differing nature — correlated external static and alternative fields, plasma turbulence fields, microfields generated by charged particles. Techniques based on classical emission spectroscopy, and novel linear and nonlinear laser techniques are considered. It is shown that the application of recently developed coherent laser spectroscopic methods radically improves the possibilities of electric fields measurements for the high pressure range.
