1·The electron soon attaches itself to another molecule, making a negatively charged ion.

电子很快被另一个原子所吸附，使之成为负离子。

2·Traditional fuel cells work by using a catalytic material to oxidise a fuel, such as hydrogen, turning it into a positively charged ion and a negative electron.

传统的燃料电池使用催化材料来氧化燃料，比如氢气，使之转变为一个带正电的离子与一个电子。

3·A study of doubly charged ion mass spectra (2E spectra), the substituents effect and the target gas pressure deppendence of biphenyl derivitives was presented in this work.

本文研究了联苯取代物双电荷离子2E谱及其取代基效应和靶气压力影响。

4·The electron beam ion trap(EBIT) and the electron ion source(EBIS) are new instruments for the study of X-ray produced by very highly-charged ions when they interact with free electrons.

利用电子束离子源（EBIS）或者电子束离子陷阱（EBIT）产生的慢速高电荷态重离子束轰击金属靶面，离子束与靶面作用并复合辐射特征X射线；

5·Radiation from the sun pushes dust particles away from the coma, forming a dust tail, while charged particles from the sun convert some of the comet's gases into ions, forming an ion tail.

从太阳而来的辐射，将尘埃粒子吹离彗发，形成尘埃彗尾；同时，来自太阳的带电粒子将一些彗星气体电离成离子，形成离子彗尾。

6·Light emitted from farther away, and thus older, quasars lacked this wavelength, because the light was getting absorbed by neutral helium as well as helium with a single ion-or charged particle.

光线的发射处越远，年龄越大，类星体的光谱会缺失，因为某些波长的光线会被中性氦及氦离子或带电粒子吸收。

7·An ion channel is a protein that lets charged particles enter or leave a cell to generate electrical signals, a basic process of nerve cell communication.

离子通道是可以让带电粒子进入或离开细胞，产生电信号的一类蛋白，是神经细胞交流的基础。

8·Ion channels sit in a cell's outer membrane and let electrically charged atoms (ions, as they are known in chemical jargon) in and out of the cell.

离子通道位于细胞外膜，使带电荷原子(即化学术语中的离子)可以进出细胞。

9·It has a range of 393km (244 miles) once its lithium-ion battery pack is fully charged (which, admittedly, takes several hours).

锂电池充满电（不可否认，这需要几个小时）以后巡行里程393公里（244英里）。

10·The Prius Plug-in, which seats five people, comes with a new lithium-ion battery that can be charged from a household outlet, much like an electric car.

五座普瑞斯插件版装备了最新的锂电池，可以用家用插座充电，更像是一台电动车。
