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。

Using a potential model with relativistic correction we evaluated the spectrum, lepton decay widths and radiativetransition widths of heavy quarkonium systems.
本文用考虑了相对论修正的势模型计算重夸克偶素的能谱、轻子宽度和辐射跃迁宽度。

The dependence of radiative and nonradiative transition probability on the temperature is discussed, and the curve of concentration quench and temperature quench is given.
