Although hydroxyl radicals are degraded by pollutants, says Rohrer, some of these same molecules also help to recycle OH.

虽然氢氧自由基因为消灭污染物而减少，Rohrer说，但是也有些相同的分子能帮助它们再生。

Because a molecular is the rotatable charge group, there is an attraction force between molecules.

因为分子是能自由旋转的电荷群，所以分子之间存在相互吸引力。

In the case of low doping concentration of porphyrins and long interchain distance, the rotational motion of porphyrin molecules is the main reason of fast luminescence decay and low luminescence efficiency.

在卟啉低掺杂浓度和聚合物分子链间距离较大的情况下，卟啉侧链基团的旋转成为影响荧光寿命和发光效率的主要因素。

In this thesis, a realization of laser cooling and trapping of rubidium atoms is reported. Firstly, the history and development of laser cooling and trapping of neutral atoms and molecules is reviewed. Present study status and future development is prospected.

本学位论文围绕Rb原子的激光冷却与囚禁，报道了以下几个方面的工作：综述了激光冷却与囚禁原子、分子的研究历史及发展过程，介绍了国内外的研究现状和最新成果，展望了原子的激光冷却与囚禁技术的应用前景。

The temporal effect is said to occur while sample molecules are passing a fixed-position detector. Since the sample dispersion keeps changing during the monitoring, the signal recorded should be different from that of the true sample distribution in the flow.

所谓时间效应是指样品在管路里流动时，由於在管中产生的分散现象，会导致样品在通过侦测器之时，样品的分布会因流动而改变，因此所测得样品之讯号和实际样品之分布并不相同。

British biochemists Sanger invented RNA and DNA molecules identified in the order of the base technology.

英国生物化学家桑格发明了确定 RNA 和 DNA 分子中碱基排列顺序的技术。

Normally, to be tasted, a potentially sapid or instable substance must go into solution upon coming in contact with saliva, which limits instable chemicals to watersoluble molecules.

正常来说，要是尝的话，一种潜在的美味或者不稳定的物质必须在进入嘴与唾液接触之前变成液体。这也就限制了不稳定的化学物质为水溶性分子。

Background— Caveolae, lipid-rich microdomains of the sarcolemma, localize and enrich cardiac-protective signaling molecules.

背景---细胞质膜微囊是肌纤维膜上的富含脂质的亚结构，诸多心脏保护性信号分子均富集于此。

I n the High and Far off times, O Best Beloved, there were young scientists who were full of 'satiable curiosities about the molecules of bygone life.

在遥远的过去，有着许多对古代生命分子充满了好奇的年轻科学家。

The interaction of chemical molecules and biological ones, especially sequence specific recognition and site-specific cleavage of DNA have many applications such as in DNA sequence determinations, chromosome analyses, gene therapeutics, and recombinant DNA manipulation. So it is significant to develop artificial enzymes for the scission of nucleic acid with high activity and selectivity at normal condition.

化学小分子与生物大分子的相互作用，尤其是人工核酸定位切断试剂对DNA的切断在DNA序列测定、染色体分析、基因治疗以及DNA重组方面有着广泛的用途，因此进行人工合成核酸定位切断试剂及其与DNA的相互作用的研究具有重要的理论意义和应用价值。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
