You wrote that article on the positron.

你写过关于正电子的那篇文章。

The positron cannon is ready to fire, and you're safe.

正电子炮已准备好开火 你安全了。

All have had what it takes to serve as a cathode for a battery: namely, an ability to have electrons ripped away from their atoms to be turned into electric current, leaving positively charged ions behind.

所有这些元素都具备作为电池阴极的条件：即能够将电子从原子中剥离出来，转化为电流，留下带正电的离子。

Even when we look at every component of the bee separately, we'll find a masculine and feminine aspect, until we reach the level of the atom, in which we encounter a positively charged core surrounded by negatively charged electrons.

即使我们单独观察蜜蜂的每一个组，我们也会发现一个男性和女性的面，直到我们达到原子的水平，在这个水平上，我们会看到一个被带负电荷的电子包围的带正电荷的核心。

When a bunch of metal atoms come together in a chunk, these outer electrons wiggle free, creating what scientists usually think of as a negatively-charged “sea of electrons” flowing around a network of positively-charged ions.

当大量金属原子聚集结合为块状，这些外层电子自由移动，就产生了科学家通常所的电子海，即大量带负电荷的电子游荡在带正电的金属阳离子周围。

Now, more research on this topic definitely needs to be done, but the basic idea is that we as humans have a slightly positive electric charge on our bodies, and the Earth has a slightly negative electric charge.

当然，关于这个话题还需要进行更多的研究，但其基本理念是：我们人体带微量正电荷，而地球带微量负电荷。

When a neon sign is turned on, the electric current causes some of the neon atoms' electrons to accelerate and break free of their orbits, leaving behind positively charged ions.

当霓虹灯广告牌被打开，电流使一些氖原子的电子加速并脱离轨道，留下大量带正电荷的离子。

For any interaction to happen, these two protons, each has a positive electric charge and so they would repel each other, so you got to get them close enough together.

为了让两个中子发生相互作用，它们各有一个正电荷因此相互排斥。所以你得让它们充靠近。

But an analysis of results from the LHCB experiment (pictured), a purpose-built detector fitted to CERN's Large Hadron Collider (LHC), suggests electron-positron pairs are more abundant than muon pairs.

但是对LHCB(欧洲核子研究中心的大型强子对撞机(LHC)专用探测器)实验结果的析表明，电子-正电子的数量对比介子对更多。

As soon as the positively-charged calcium and negatively-charged phosphate are released from the bones, they grab onto each other again, meaning that the ionized calcium level doesn't really go up very much at all.

一旦带正电的钙和带负电的磷酸盐从骨头中被释放出来，它们又再次相互吸附，这意味着游离钙离子的水平并没有上升很多。

Remember that at rest, cells are negatively charged relative to the slightly positive outside environment and when they depolarize, the cells become positively charged, leaving a slightly negative charge in the outside environment.

要记住在静息状态下，细胞带负电，其外环境则相对稍带正电；当它们去极化时，细胞带有正电，它的外环境带有负电。

Our models of how subatomic particles behave predicts that over very long periods of time, protons — the positively charged particles in the nuclei of atoms — will decay.

我们关于亚原子粒子行为的模型预测，经过很长一段时间后，质子——原子核中带正电荷的粒子——将会衰变。
