能级间的跃迁 meaning in Chinese

transition between energy level

The method plays an important role in distinguishing and studying the complicated and confused spectral characteristics and mechanisms of the rare earth . ( 2 ) it is found and explained that due to the boltzmann distribution law at room temperature , the positions of the fine peaks of the photoluminescence band stemming from the transitions between an excited state and the ground state of a re3 + , match these of the absorption bands from the transitions between the ground state and the excited state . the stark split energy levels of the ground state 4i15 / 2 and two excited states 2s3 / 2 and 4f9 / 2 of the er3 + in er203 have been determined
薛理辉武汉理工大学博士学位论文摘要( 2 )发现在常温下，由于boltzm ~分布律的作用，在re3 +的基态电子态和激发态间跃迁所产生的发光谱带和吸收谱带中的精细谱峰的位置一一相同，解释了产生这种关系的原因，并弄清了er203中er3 +的基态电子态4lts . 12和激发态电子态2凡/ 2 、 4凡/ 2的stark能级分裂情况，确定了常温下erzo3中er3 +的4了15 / 2一2凡/ 2和‘ i ， 5 / 2一‘凡/ 2精细能级间的跃迁形式。
