In this paper, the development of trace vanadium element in chemistry and life science has been reviewed.

本文概述了微量元素钒在化学和生命领域中的研究进展。

The supermolecule system building on the weak interactions between molecules has always been the focus on chemistry , bionomy , material science and informatics theoretically and experimentally . However , because the experiments fail to provide varied information in detail .

通过分子间弱相互作用构筑的超分子体系一直是化学，生命科学，材料科学，信息科学领域在理论和实验上的研究焦点，但对于分子间的相互作用体系，实验研究不能提供十分详细的各种信息，所以量子化学计算在补充其结构，能量，光谱等信息上有着重要的意义。

At these nadirs, chemosynthesis—the thermal and chemical energy given off by deep-sea vents—gives life to creatures like the eelpout fish and tube worms pictured here.

在这些最低点，化学合成，热和化学能给予在深海排气口之外，让生命的生物像粘鱼之类和管蠕虫拍到这里。

It is one of the trends of chemistry to use electrochemical methods in studying biological phenomena.

以电化学方法研究生命科学现象已是当今化学发展的方向之一。

Then comes computer science and health and ''.

接下来的是计算机、保健和生命科学，如：生物、化学和物理。

The spacecraft's sensitive spectrometer was able to register the chemical signatures not only of water vapor but also of hydrogen cyanide, carbon monoxide, and carbon dioxide--all precursors of the more complex molecules that scientists think eventually gave rise to life on Earth.

斯必泽太空望远镜上敏感的光谱仪不但能够记录水蒸气的化学特征，还能够记录氰化氢、一氧化碳和二氧化碳的化学特征，这些都是更为复杂分子的初级粒子，科学家们认为是这些初级粒子最终导致了地球生命的产生。

Thesynthesized chemical messengers include phospholipid-derived leukotriene B 〓, sphingolipid-derived sphingosine, ceramide, phytosphingosine, and new sphingosine derivativetetrahydroxyl long chain bases.

在核酸和蛋白质继续占据着生命科学中心的同时，脂质及其代谢物、糖及糖缀合物在生命过程中的作用，特别是它们的化学信息物质作用，正被不断揭示，引起了广泛重视。

The Exobiology Branch conducts research in Exobiology seeking to increase our knowledge of the origin, evolution, and distribution of life in the universe, such as chemical evolution occur in the primitive bodies of the solar system, evidence regarding the early interplay between biological and environmental evolution, and molecular fossils about early microbial evolution so on.

外太空生物学分部致力于研究外太空生物学，探索宇宙生命的起源，演化和分布，例如太阳系最初生命的化学演化，有关早期生物和环境的演化相互影响的证据，以及有关早期微生物进化的分子化石等。

Under the right circumstances methane can play a key role in prebiotic chemistry -- the chemical reactions considered necessary to form life as we know it.

在合适的条件下，甲烷在生命前化学中起着关键作用，——被认为是形成生命的必要条件的化学反应。

This work will lay the groundwork for the type of analysis astronomers eventually will need to perform in shortlisting any promising rocky Earth-like planets where the signatures of organic chemicals might indicate the presence of life.

这项工作将奠定分析类型的基础，天文学家最终将寄希望于具有岩石表面特征的类地行星上，如果这类行星上发现支持生命的化学成分，则可能表明有生命存在。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
