为了研究低温液体中电弧放电制备碳纳米材料的条件，测量了低温液体（如液氦）中电弧放电的放电特性和发射光谱。测量所得到的等离子体的放电特性和相关的光发射光谱的观察表明，放电电流随时间的行为和相关的光谱强烈依赖于放电电压，两者都可能与碳靶的温度。然而，无论液体是纯水、液氮、液氦还是超流液氦，放电电压和电流随时间的变化几乎相同
Discharge characteristics and emission spectra of the discharges in low-temperature liquid such as liquid helium have been measured to investigate the conditions for fabrication of carbon nanomaterial by arc discharge in low-temperature liquid. Measurements of the discharge characteristics of the resulting plasma and observation of the associated optical emission spectra show that the behaviour of discharge current over time and the associated spectra depend strongly on discharge voltage and both may be related to the temperature of the carbon target. However, discharge voltage and current with time are almost the same regardless of whether the liquid is pure water, liquid nitrogen, liquid helium and superfluid liquid helium
