本文综述了用于材料和结构试验的低密度电弧射流中流动特性的确定技术。测量的特性包括流动总焓、压力、热通量、静态温度、电子密度、物种浓度和流速。所涵盖的探测技术是压力、热通量、静电和质量取样。非侵入性技术包括发射光谱、激光诱导荧光、激光汤姆逊散射和拉曼散射。它的结论是，必须使用几种技术在一个单一的设施，以获得所有的流场特性预测在非平衡膨胀热通量。
This paper reviews techniques for determining flow properties in low density arc jets used for materials and structures testing. Properties measured include flow total enthalpy, pressures, heat fluxes, static temperatures, electron density, species concentrations, and flow velocity. The probe techniques covered are pressure, heat flux, electrostatic, and mass sampling. Nonintrusive techniques include emission spectroscopy, laser-induced fluorescence, laser Thomson scattering, and Raman scattering. It is concluded that several techniques must be used in a single facility to obtain all of the flow field properties necessary to predict heat fluxes in a nonequilibrium expansion.
