本文测量了大气压大电流自由燃烧氩弧的阴极表面温度和等离子体温度，并给出了不同锥角的钍钨阴极的实验结果。这些测量表明，阴极的表面温度和等离子体的温度强烈地依赖于阴极的形状。对于具有圆锥形状的阴极，等离子体温度被发现是最大的阴极锥角为60度。
The temperatures of the cathode surface and of the plasma for an atmospheric-pressure high-current free-burning argon arc have been measured for a range of cone angles for cathodes of thoriated tungsten. These measurements have shown that both the surface temperature of the cathode and the temperature of the plasma depend strongly on the cathode shape. For cathodes with conical shape, plasma temperatures were found to be a maximum for a cathode cone angle of 60 degrees .
