A method to determine the electron temperature and density from the time resolved spectra of hydrogen atoms left in a pulsed laser plasma is described.
The novel Gd-containing sulfide glasses were investigated. Some glass properties including infrared spectra, microhardness, density and the curves of XRD and DSC were tested.
研究了新型含钆硫化物玻璃，测试了玻璃的红外透射光谱、显微硬度、密度等性能以及XRD ，DSC曲线。

Furthermore, the energy density spectrum for electromagnetic wave, Langmuir wave and ion acoustic wave are obtained and used to interpret spectra evolution with time.
