通过回顾、比较和解释现有的实验方法和获得的数据，探讨了在电弧加热发动机风洞中进行比迄今为止已经实现的更精确的测量的方法。本文首先指出了传统的测定焓和流动均匀性方法的不准确性。接下来检查铜蒸气的低污染的程度和后果。然后，通过光谱测定的流，多普勒测速利用激光诱导发光，和物种浓度测定用质谱法获得的数据进行了审查。指出了计算值与实测值之间的差异，并给出了可能的解释。
The methods of making more accurate measurements in arcjet wind tunnels in the real-gas regime than have been achieved up to the present time are explored by reviewing, comparing, and interpreting the existing experimental methodologies and obtained data. The inaccuracies of the conventional method of determining enthalpy and e ow uniformity are e rst pointed out. The extent and consequences of e ow contamination by copper vapor are next examined. Then the data obtained through spectroscopic determination of e ow enthalpies, Doppler velocimetry using laser-induced e uorescence, and species concentration determination using mass spectrometry are reviewed. The discrepancies between the measured and calculated e ow velocities and species concentrations are pointed out and a possible explanation is given.
