辐射寿命 meaning in English
radiative lifetime
Examples
- The spectra parameters of these crystals can be calculated by the f - l formula , which show that the crystals are applicable for the tunable laser and femtosecond laser because of their large emission broadband ( fwhm 50nm )
用f ? l公式计算了晶体yb3 +的2f7 / 2 2f5 / 2能级跃迁的发射截面、辐射跃迁几率、辐射寿命等光谱参数。 - By using the multi - configuration dirac - fock ( mcdf ) method , the effects of relaxation and correlation on the transition energies and probabilities of electric - dipole allowed ( el ) resonance and intercombination transitions for 2p53s3 - 2p6 in neutral neon have been systematically studied firstly . and the results of the transition energies and probabilities ( lifetimes ) in length and velocity gauge have been presented . during the calculation , in order to consider the rearrangement effects of the bound - state density and some important correlations , the asfs of transition initial - and final - states were divided according to their angular - momentum and parity and calculated , and different number of csfs were included in the expansion of asfs
