The thermosensitivity of gels have a mechanical relaxationtransition region which become more clearly with the increase of the content of carboxylic group, and thermosensitivity of gels increase.
The relaxation rate of upper level is equal to the transition probability of stimulated emission.
激光达到饱和强度时,上能级弛豫速率等于受激跃迁几率。

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