It was shown that the ion density is higher and the electron temperature is lower in the vicinity of inductively coupled plasma sheath according to the ionicline and atomic line.
原子谱线和离子谱线特性分析表明，在鞘层附近区域感应耦合等离子体具有较高的离子密度和较低的电子温度。

Lastly we put forward that with the rising of the temperature of spectra thermal line shift, stealth of Hyper-spectral will be realized according to the metal ionic crystal.
