It has been shown that the isotope substitution changes the spectrum of lattice vibration, and brings forth a great influence on the non-radiativetransition.
分析表明，同位素替代改变了晶格振动的频谱，对无辐射跃迁产生很大的影响。

In this paper, the radiativetransition probability, non-radiativetransition probability, cross relaxation probability and other spectral parameters are calculated in detail.
