So anything that goes from a higher energy level to2 is going to be falling within the Balmer series, which is in the visible range of the spectrum. 任何更高能级到2能级2,都是属于Balmer系,它在可见光谱中。
In the channel of direct excitation of target H_2, O_2, the emission spectra of Balmer series H_ α, H_ β, H_ γ, and Ol have been measured. 在靶H2,O2直接激发过程中,测量到了巴耳末系Hα,Hβ,Hγ和OI的发射谱。
Hydrogen plasma has been excited by helicon wave and the intensities of the first three lines of Balmer series have been measured. 采用螺旋波激发氢等离子体,测得氢的Balmer线系前三条谱线的强度。
An explanation to intensity of hydrogen spectra is given with the use of quantum mechanics, and the Lyman and Balmer series are calculated. 应用量子力学知识对氢光谱的强度分布给予了理论解释,并计算了赖曼系、巴耳末系头三条谱线强度之比。
