dark decay 中文意思是什麼
dark decay
解釋
暗衰減-
In addition, experiments are under way to detect mysterious particles that form the cold dark matter of the universe and to examine protons at higher levels of sensitivity to learn whether they decay
此外，已經有實驗開始偵測構成宇宙冷暗物質的神秘粒子，精密度較高的實驗也在檢查質子是否會發生衰變。 -
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
體全息存儲的首選記錄材料是光折變晶體（如fe : linbo _ 3 ） ，但直接存儲在晶體中的信息容易受光和熱的影響而丟失。 -
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
研究表明這種紫外光誘導的電荷遷移帶變化是由於eu ~ （ 3 + ）離子周圍局域環境發生的變化引起的。 -
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
首次在實驗和理論上研究了自泵浦位相共軛光柵暗衰減的特性，與以往一深一淺兩個陷阱能級參與光折變過程不同的是，發現了兩個深陷阱能級同時參與了自泵浦位相共軛光柵的建立。 -
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雙光束干涉光折變光柵的暗衰減實驗中，也觀察到了符合雙deep模型的衰減現象，得到光折變空間電場快衰減時間常數714s ，約12分鐘。 -
Still dark green near its stem, with its serrated edges tinted with the yellow of dissolution and decay, it hung bravely from the branch some twenty feet above the ground
靠近莖部仍然是深綠色，可是鋸齒形的葉子邊緣已經枯萎發黃，它傲然掛在一根離地二十多英尺的藤枝上。
