dark decay meaning in English
暗衰减
Examples
- The dark decay of the spectral change was also studied . two recovery time constants were obtained by fitting . one is 2 . 5 hours and the other is longer
研究表明这种紫外光诱导的电荷迁移带变化是由于eu ~ ( 3 + )离子周围局域环境发生的变化引起的。 - Doped linbo3 ) have been considered as one kind of the most important materials for vhs owing to wider dynamic range and their commercial availability in large size . however , the volume holographic gratings in photorefractive crystals are liable to dark decay and erasure under readout illumination
体全息存储的首选记录材料是光折变晶体(如fe : linbo _ 3 ) ，但直接存储在晶体中的信息容易受光和热的影响而丢失。 - Experimental results are reported on temporal instability of phase - conjugate beam in a self - pumped ce : batio3 phase conjugator at 532nm . dark decay behaviors of sppc gratings in ce : batio3 are studied , for the first time to our knowledge , by measuring the decay of sppc reflectivities at 532nm and 790nm wavelengths at room temperature
首次在实验和理论上研究了自泵浦位相共轭光栅暗衰减的特性，与以往一深一浅两个陷阱能级参与光折变过程不同的是，发现了两个深陷阱能级同时参与了自泵浦位相共轭光栅的建立。 - We present a charge - transport model of the photorefractive effect with two deep traps ( two deep - trap model ) based on one deep - trap model and shallow - deep - trap model . we also found dark decay behaviors which accord with the two deep - trap model in the two - beam interference experiments . the fast decay - time constant of the space - charge field is obtained as 714s
此外，在ce ： batio _ 3双光束干涉光折变光栅的暗衰减实验中，也观察到了符合双deep模型的衰减现象，得到光折变空间电场快衰减时间常数714s ，约12分钟。
