查询词典 singlet

A flow-injection chemiluminescence method for the determination of melatonin based on the CL reaction of melatonin with hydrogen peroxide and sodium hypochlorite in a basic alkaline solution was developed. The possible CL mechanism has been discussed, and a proposal for the reaction pathway was given that singlet oxygen was clarified to be produced in this reaction system and was responsible for the CL emission.

研究了褪黑素在碱性介质中与过氧化氢和次氯酸钠反应产生化学发光的行为；初步探讨了其化学发光反应的机理；提出了可能的化学发光反应历程；建立起流动注射化学发光测定褪黑素的新方法。

Density functional calculations predicted that both the ZrO3 and HfO3 molecules possess a closed-shell singlet ground state with a non-planar Cs geometry, in which the side-on coordinated O2 falls into the peroxide category.

结果表明ZrO3和HfO3都具有单重电子基态以及非平面的Cs构型，可以看作金属一氧化物二价正离子与过氧配体形成的络合物。

Fluorescence emission spectra and UV absorb spectra analysis have been undertaken to test the influence of solvent polarity on the lowest excited singlet state of the tertiary amines. The absorption maxima were red-shafted slightly, and the emission maxima were red-shafted strongly, which showed all of the three compounds were found to be essentiallyππ* in character, which makes for the formation of triplet-exciplex state and the subsequent reactions,?known as photo-reduction and hydrogen-abstraction.

本文借助光谱检测的手段测试了新合成的增感剂的光物理化学性能，利用荧光发射光谱和紫外吸收光谱测试了溶剂极性对叔胺的最低激发单重态的影响，实验结果表明叔胺的紫外最大吸收波长随溶剂极性的增强产生轻微的红移，荧光最大发射波长随溶剂极性的增强产生明显的红移，表明三种叔胺的最低激发单重态具有ππ*跃迁的特性，这对于激态复合物的生成以及其后的光致还原反应和提氢反应的发生都非常有利。

Now, in a study that took more than five years to complete, Rockefeller University researchers, in collaboration with a team of bacteriologists at the University of Wisconsin, Madison, have become the first to solve the structure of a protein complex that protects these cells from singlet oxygen.

现在，洛克菲勒大学的研究人员与威斯康星大学的细菌学家一同协作，历经5年多时间的研究，首次获得了一种能够保护细胞免受单态氧损伤的蛋白复合体的晶体结构。

Talk about Justin caught on camera by paparazzi, Ron honestly sympathises with him: Poor thing, I try to keep my curtains drawn when I am home because I'm usually in shorts, singlet and walk around with my hair uncombed, it's pretty unsightly and not nice if someone sees me!

谈到侧田被周刊偷拍，阿 Ron 坦言十分同情对方：「佢好惨，我喺屋企都尽量拉晒窗帘，因为我平时都只系着短裤、底衫，唔梳头行嚟行去，都几不雅，畀人睇到都唔好啦！

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
