碳氢化合物被允许进入实验室等离子体，以研究含碳分子在熔合边界等离子体中的再沉积过程的输运过程。当在等离子体中引入CH 4时，CH自由基谱带被光学识别，而在引入C2 H2的情况下，除了CH自由基外，C2自由基也被识别。相对于轴向输运，CH-自由基带的光谱强度的特征衰减长度小于C2自由基带的。从CH和C2带光谱确定的激发温度被观察到增加接近目标。
Hydrocarbons are admitted into a laboratory plasma in order to investigate the transport processes of carbon-containing molecules in relation to redeposition processes in a fusion boundary plasma. When CH4was introduced into the plasma, CH radical band spectra were optically identified, while in the case of C2H2introduction, C2radicals were also identified in addition to CH radicals. With respect to the axial transport in the plasma the characteristic decay length of the spectral intensity of the CH-radical band was smaller than that of the C2radical band. The excitation temperature determined from the CH and C2band spectra was observed to increase on approaching the target.
