一种用于确定气体输运性质的受限电弧被发展到这样的程度，即所得到的性质被发现在几个百分点之内。测量内容包括电弧电梯度特性、流动压降、辐射传热、光谱温度分布和微波谐振特性。列出了7500 ~ 13750 °K温度范围内平衡态氩的电导率和热导率值。氦在大气压下的限制电弧中，在高达400 A的压力下，不处于热力学平衡状态，因此不能通过使用这种实验装置来确定其平衡性质。
A confined electric arc for the determination of gas transport properties is developed to the point that the resultant properties are found within a few percent. The measurements include the arc electrical gradient characteristic, the flow pressure drop, the radiative heat transfer, the spectral temperature distribution, and microwave resonance characteristics. Values of the electrical and thermal conductivity of equilibrium argon are tabulated for the temperature range from 7500 to 13 750°K. Helium in the confined arc at atmospheric pressure up to 400 A is shown not to be in thermodynamic equilibrium and hence its equilibrium properties cannot be determined by use of this experimental arrangement.
