退激 meaning in English
de excitation
deexcitation
Examples
- Some of the excited atoms undergo radiative deexcitation .
某些受激的原子会发生辐射性退激。 - The experiment populated the excitation state of 64cu via 64ni ( p , ny ) 64cu * reaction and the lifetime of low - lying excitation state of 64cu were determined via the delayed coincidence method between pulse proton beam and de - excitation y rays detected by ge ( li ) detector
Sns ）与ge （ l ）探测器测量退激y射线延迟符合的方法，由时间谱tof峰的中值移动的方法来确定激发态寿命。 - Its principle can be outlined as follows : the accelerator produces a beam of fast ions which directs through the foil , because of collisions with the foil atoms the fast ions may undergo further ionization , and they often emerge from the foil in excited electronic states
其原理如下：加速器产生的高能离子束与碳箔相碰撞而失去电子，同时剩余电子被激发到高激发态，在随后的退激过程中发射谱线，通过研究这些谱线可以得到原子的能级结构。 - Output of high purity violet blue light matches the peaks optical absorption of acne aminolevulinic acid , metabolites inside the porphyrin , propionibacterium acnes metabolites inside the porphyrin stimulated by the withdrawal - induced chemical processes produce large singlet oxygen activity and generate a high oxidative environment to propionibacterium acnes , which accordingly leads to the death of bacteria on the skin acne cleared
输出高纯度的紫蓝光，与痤疮丙酸杆菌代谢物内卟啉的光吸收峰值匹配，痤疮丙酸杆菌的代谢物内卟啉受到激发后的化学退激过程产生大量单线态活性氧，可对痤疮丙酸杆菌产生一种高氧化环境，从而导致细菌死亡进而将皮肤上的痤疮清除。 - The lifetime of the first excitation state of 64cu on the same experiment published was i = 22 ? 9ps and t = 29 . 8 ? . 4ps respectively . multipole mixing ratio ( 8 ) of the first excitation state of 64cu , that p . w . green had studied through the angular distributions of de - excitation y rays following the 64ni ( p , ny ) reaction was determined to be s = 0 . 12 ? . 04
至于多极混合比，在1976年pwgreen等人同样利用以nio ， fly ）反应，通过退激y射线角分布测量，给出了时cll第一激发态的多极混合比为： 6二0l士0刀4 。
