能级跃迁 meaning in Chinese
energy level transition
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。 - Ar n2 ) are exhibited . we obtain the complete information and a whole microscopic picture of the intermolecular actions and relative motions of these complexes . all observed bands are rationally assigned by isotope effect and calculated at the internal rotational levels and external vibrational levels are obtained
由理论计算和同位素效应对光谱的分析作了合理的归属，获得了复合物c _ 6h _ 5ch _ 3 … n _ 2 、 ar的分子间相对振动模式和内转动的能级跃迁完整信息。 - For the sake of the practical application , the 1s to 2p transitional spectra of the group composed by na10 + and al12 + or another group composed by mg11 + and si13 + will be selected to use in the calculation about relation of relative intensity of spectra and electronic temperatures for making theoretical values approaching practice
计算所得的能级跃迁波长、自发跃迁几率a 、受激跃迁几率gb和振子强度是对实验所用光谱数据的补充。此外研究表明，利用z = 2的不同元素作示踪元素进行温度诊断是合理可行的。 - We then discuss the vibrational - rotational level transitions and the population rate equations for the laser . in addition , electron temperature , electron density and the mixtured gas temperature in the laser plasma are investigated in details . the third part is with regard to the optimal designs and the experiments of the lasers
在二氧化碳激光动力学机理的研究中，比较详细地讨论了二氧化碳激光动力学过程，给出了激光振动-转动能级跃迁及其速率方程、激光等离子体电子密度和电子温度，以及混合气体的气体温度 - It is found that the exciting spectra is moving to long wave with the increasing of eu concentration , emission intensity is rising , the properity of red homochromy is becoming better because of the different quench concentration of emission levels 5do , 5dj and 5d2 - when the concentration of eu is up to 1 . 2mol % , the emission levels 5di and 5d2 is quenching
研究发现，随着eu浓度的增加，荧光体y2o2s ： eu激发光谱发生红移，发射强度增大，红色单色性变好，这是因为eu的5d0和sdl 、 5d2发射能级跃迁发光的淬灭浓度不同，当浓度1 . 2mol时，后两者因交叉弛豫引起浓度淬灭。
