在一些教学和参考书籍中,关于原子发射光谱谱线数与吸收光谱谱线的对应关系问题,以及发射光谱在一定条件下可以实现反转,成为吸收光谱问题,常出现概念上的含混,为辨明这两问题,特作如下讨论.1 发射光增与吸收光谱的成因一般热体发光的特点是辐射能量与物体温度有关,温度越高的物体相应辐射能量越大.电炉上的电炉丝主要辐射红外线和红光,而一条热得多的白炽状态的灯丝和炼钢炉里耀眼的钢水则能发出包括由红到紫的所有可见光在内的白光.
In some teaching and reference books, the problem of the correspondence between the number of lines of atomic emission spectrum and the spectrum of the absorption spectrum and the fact that the emission spectrum can be inverted under certain conditions becomes an issue of absorption spectrum and often appears conceptually ambiguous. These two issues are identified and discussed as follows. 1 Genesis of Enhanced Light Emission and Absorption Spectroscopy General The characteristics of thermal emission are that the radiation energy is related to the temperature of the object. The higher the temperature, the higher the corresponding radiation energy of the object. The main electric wire on the electric furnace is mainly Radiation is infrared and red, and a much hotter incandescent filament and dazzling molten steel in a steelmaking furnace can emit white light, including all visible light from red to violet.
