This article is devoted to the measurement of the appearance potential of the Same molecule ion in two processes and of the dissociation energy of molecules by mass Spectrometry.

本文测定设计的两个过程中同一分子离子的表观电势，用质谱法测定出分子的离解能。

Arnsten said that the aging prefrontal cortex appears to accumulate excessive levels of a signaling molecule called cAMP, which can open ion channels and weaken prefrontal neuronal firing.

Arnsten认为，衰老的前额叶皮层中积累了过多的信号化学分子，称为环腺苷酸(Camp)，它能打开离子通道，从而削弱前额叶皮层中神经元放电的频率。

Fortunately for the tea drinkers of Britain, Prussian blue is a complex molecule, so it is almost impossible to release the cyanide ion from it and the poison passes harmlessly through the body.

但那些英国的饮茶人士还算走运，普鲁士蓝是一种化合物分子，它在人体中几乎没可能释放出氰根离子。所以这种物质最终将安全无害的从人体中排出。

So, let's try another example here, and let's try a case now where instead of dealing with a neutral molecule we have an ion, so we have c n minus.

那么，让我们来试一下另外一个例子，这次不是一个中性原子,而是一个离子，氰离子。

now we're dealing with a lot of different atoms in the molecule, much more complicated than the initial case of the cyanide ion where we only had two.

现在我们要面对的分子中有很多不同的原子，比我们一开始只有两个,原子的氰离子复杂多了。

In the presence of this ligand, this molecule, it's open, it allows transport of this ion, when the ligand is gone it doesn't.

配体存在的情况下通道才打开,允许这些离子穿过,配体离开后,这些离子就不能通过了

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

If you zap purified water with electric current, you can split apart a water molecule into a positively charged hydrogen ion and a negatively charged hydroxide ion (oxygen attached to hydrogen).

The theory is that when a muon encounters a gas molecule, it can knock off an electron, leaving a positively charged ion in its wake.
