单线

In the process, chloranil firstly was excited to singlet state and then a labile hydrogen abstraction interaction between singlet chloranil andβ-diketones was involved to form singlet stable neutral radical pairs.

光照作用下，四氯苯醌首先跃迁至单线态，然后夺取β二酮类化合物分子中的活泼氢，形成单线态中性自由基对。

They have a wide of biological effects, including antioxidation, free radical scavenger and chelators of divalent cations etc.

其中，槲皮素是很强的单线态氧的猝灭剂，能有效抑制单线态氧引起的对类胡萝卜素的破坏。

In the common case of single-threaded applications, there is a one to one correspondence between the two methods of enforcing resource limits, but in the case of multi-threaded applications, this prevents a single user from being able to gain a larger portion of the CPU time than would be possible with multiple single-threaded applications.

在通常的单线程程序中，两个方法在限制资源的权限内进行一对一的通信，但在多线程的程序中，这样防止一个用户获得比多个单线程程序更多的CPU时间。

Adding single oxygen quencher and superoxide anion quencher could increase the stabilities and single oxygen was the main reason for photooxidation.

加入单线态氧猝灭剂和超氧负离子猝灭剂均能提高染料的光稳定性，但单线态氧猝灭剂的作用更为明显。

In contrast with ground state oxygen,singlet oxygen has a higher chemical reactivity due to its unpaired electrons.

简要介绍了单线态氧的性质、制备方法和应用领域，着重介绍了近期单线态氧用于纸浆漂白方面的有关研究和探索。

There was no obvious correlation between relative lipophilicity and activity in the current study. Na2Fl showed obvious synergetic action to other xanthene derivatives; it also show obvious synergetic action as combined lipophilic xanthene chemical and hydrophilic xanthene chemical.

由物化性质和生物活性的测试结果可知：光敏生物活性的测试与单线态氧的测试结果保持了高度的一致性，用单线态氧的产率这个指标来评价对微生物的光敏活性比用亲脂亲水性指标更为有效。

We took the cultured suspension cells ofPanax ginseng as our experimental material, studied the generation of singlet oxygen whichinduced by fugal elicitor, testified the singlet oxygen acted as a signal molecule in plantdefense responses.

我们以人参悬浮细胞为实验材料，研究了真菌激发子诱导下单线氧的产生情况，进一步证明了单线氧在植物防卫反应中作为信号分子的作用。

Absorption spectra indicate that there is little or no interaction between chromphores in the ground state. However, the fluorescence emission of oxadiazole and triphenylamine moieties are almost quenched, which shows that in the excited ground state there exists very effective intramolecular singlet-singlet energy transfer .

研究发现，这些多发色团化合物在基态发色团之间没有作用或作用很小，而其中噁二唑和三苯基胺单元的荧光被严重的猝灭，这说明在激发态下，萘酰亚胺发色团与噁二唑、三苯胺功能团之间发生了分子内单线态—单线态能量转移。

In this paper, the properties,generation and application of singlet oxygen were introduced briefly,especially,some study and attempt utilized singlet oxy- gen for pulp bleaching in recent years were Introduced in detail.

相关研究表明，单线态氧对木素具有较强的降解能力，在漂白过程中具有较好的选择性，尤其是采用光催化法制备单线态氧用于纸浆的漂白，化学药品消耗少，对环境友好，进一步深入研究将具有广阔的应用前景。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
