( 2 ) the emission spectra of laser ablation metal copper plasma were measured. the detailed mechanism of plume emission of cu plasma was qualitatively explained using a simple model based on excitation of atom and ion in plume arising from inelastic collision between the elemental species and electron with high kinetic energy. under the local thermal equilibrium model, the electronic temperature of copper plasma was deduced to be in the 104 scale by its emission lines
( 2 ) cu等離子體光譜:在420 570nm波長范圍內觀測了激光燒蝕cu等離子體的光譜和各發射譜線在等離子體中的空間分佈;比較了激光能量對cu等離子體發射光譜、電子溫度的影響;用局部熱力學平衡( lte )近似,測得cu等離子體的電子溫度為104k數量級;在不同背景氣壓下,觀測了激光燒蝕cu等離子體光譜的空間分佈。Because the photospheric temperature of carbon stars are less than 3000k and the temperature of rich - dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro - vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars
碳星光球的有效溫度不超過3000k ,同時較大的質量損失率形成了富碳的塵埃殼層,以致於它的輻射能量主要集中在1 ? 60 m的紅外波段上,並且許多分子的轉動振動能譜也集中在紅外,因此在紅外波段的研究對揭示碳星化學成份及其分佈、塵埃形成過程、恆星大氣結構和演化狀態都有十分重要的意義。Abstract : by using the pulse - sequence model , the inverse problem of amplification of broad - spectral - bandwidth laser pulse has been studied , i. e. , to find the initial input temporal pulse profile , spatial profile , spectral distribution and fluence from the required output temporal , spatial pulse profile , spectral distribution and fluence as well as the given amplifier parameters
