What is important to remember is that the formulas represent neutral compounds where the positive and negative charges add to zero.
重要的是记住分子式是代表中性化合物，正负电荷加和为零。
The result is a double-layer distribution of charges-for example, a plane of negative heads and an adjacent diffuse cloud of positive counterions.
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。
It’s just that the total area of sites with positive and negative charges are roughly equal (the two are typically within a fraction of a percent of each other).
只是带正负电的区域总面积是大致相当的（差别不超过千百分之一）。
Everything in the universe -metals, gases, dogs, doughnuts -is made of materials with positive and negative charges.
宇宙中的任何物体都是由带有正电荷和负电荷的物质组成的。
Everything in the universe - metals, gases, dogs, doughnuts - is made of materials with positive and negative charges.
宇宙中的任何物体都是由带有正电荷和负电荷的物质组成的。
The Kelvin force microscopy scans showed that the resulting surfaces were mosaics, with areas of positive and negative charges on the order of a micrometer or less across.
开尔文力显微镜下显示试验后的表面有带正电和负电的区域，属于微米级或者更小。
Between these two tiny particles, the proton and the electron, there is a powerful attraction that is always present between negative and positive electric charges.
在质子和电子这两个微粒之间有一个很大的吸引力，而这个吸引力总是存在于正、负电荷之间。
Defeat Thaddius in Naxxramas on Heroic Difficulty without anyone in the raid crossing the negative and positive charges.
在没有人交叉正负极的情况下击败纳克·萨玛斯的塔迪乌斯(英雄困难程度)。
The normal atom has an exactly equal number of positive and negative charges, so that the atom as a whole is neutral.
正常原子中正负电荷数十完全相等的，所以从整体上看原子时中性的。
Qualitatively, the equations mean this: Electric fields point out from positive charges and into negative charges, and magnetic fields curl around currents (moving charges).
定性地看，这个方程组意味着：电场是由正电荷指向负电荷，磁场围绕着电流即移动的电荷。
When a suBstance has no net electrical charge, the total numBers of positive and negative charges within it must just Be equal.
当物质没有净电荷时，它内部的正负电荷总数必定正好相等。
