你有一个正电极，电子带的是负电荷。
You have a positive electrode here and the electron is charged negatively.
这是一个带正电荷球状的乳蛋糕，里面有一些小的负电荷的小块。
So, this is a positive sphere of custard, and inside are little, negative bits.
这就产生了电荷的一种双层结构分布——比如说一个负电荷的平面和紧邻着弥散着的带正电的相对离子云。
The result is a double-layer distribution of charges-for example, a plane of negative heads and an adjacent diffuse cloud of positive counterions.
因此，这种纳米管膜，可以同时使钠离子和氯离子(这是带负电荷)从海水里分离，从而成为一个淡化海水的便宜方式。
So a nanotube membrane that allows both sodium and chloride ions (which are negatively charged) to flow out of seawater could become a cheaper way to desalinate water.
我们开始于原子。每个原子有一个独特的带正电荷的原子核和一些带负电荷的电子(回忆一下因素周期表)。
We start with atoms — each with a distinctive positively-charged nucleus and a distinctive array of negatively-charged electrons (think periodic table).
带负电荷的微粒子——电子，在绕核运行中，相对于一个纯粹的球形而言，其轨道偏离度远远小于0.000000000000000000000000001cm。
Electrons, negatively-charged particles which orbit the nuclei, deviates from absolute roundness by less than less than 0.000000000000000000000000001cm.
这个例子是一个负电荷的硒鼓和纸张，碳粉和带正电的是共同在今天的数码复印机。
This example is of a negatively charged drum and paper, and positively charged toner as is common in today's digital copiers.
原子是物质的基本单位组成了一个密集，中央核周围有云带负电荷的电子。
The atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons.
通过在带正电荷的Co3O 4周围包裹一大层带负电荷的石墨烯，可以为高性能锂离子电池制备出一个非常有效率的阳极。
Wrapping a large sheet of negatively charged df-G around a positively charged Co3O4creates a very promising anode for high-performance Li-ion batteries.
通过在带正电荷的Co3O 4周围包裹一大层带负电荷的石墨烯，可以为高性能锂离子电池制备出一个非常有效率的阳极。
Wrapping a large sheet of negatively charged df-G around a positively charged Co3O4creates a very promising anode for high-performance Li-ion batteries.
