摘要
电子温度和电子数字密度是在血浆的描述的重要参数。在电子温度和土壤血浆的电子数字密度由激光产生了的这份报纸，脱离在不同分泌物电压与毫微秒分泌物火花结合了被学习了。Saha-Boltzmann 阴谋并且空拓宽被用来决定温度和电子数字密度。本地热平衡在毫微秒火花被完成，这被证明提高的血浆。提高的光排放，到噪音比率的信号和以在不同火花电压的信号紧张的相对标准差的稳定性详细被调查。一个相对稳定的分泌物过程在带的试验性的配置下面与 10 kV 分泌物电压的使用被观察。
Electron temperature and electron number density are important parameters in the characterization of plasma. In this paper the electron temperature and electron number density of soil plasma generated by laser ablation combined with nanosecond discharge spark at different discharge voltages have been studied. Saha-Boltzmann plot and Stark broadening are used to determine the temper- ature and electron number density. It is proved that local thermal equilibrium is fulfilled in the nanosecond spark enhanced plasma. The enhanced optical emission, signal to noise ratio and the stability in term of the relative standard deviation of signal intensity at different spark voltages were investigated in detail. A relative stable discharge process was observed with use of a 10 kV discharge voltage under the carried experimental configuration.
