电荷

• A molecule where the centers do not coincide is called a polar molecule .
  正负电荷中心不重合的分子称为极性分子。
• In a series connection the magnitude of charge on all plates is the same .
  在串联接法中，所有各板上的电荷量相同。
• The charges themselves in either case are those of electrons or protons .
  任一种情况下，电荷就是电子或质子的电荷。
• Removed of the charge or exchange of charge between particles are desirable .
  希望能除去电荷或在粒子间进行电荷交换。
• Electrostatic attraction occurs between opposite electrical charges: ＋and－ .
  静电吸引发生于相反的电荷之间：与。
• No lines of force originate or terminate in the space surrounding a charge .
  在电荷周围的空间内，并没有电力线的起点或终点。
• We regard electrons as particles because they posses charge and mass .
  我们认为电子是粒子，这是因为电子带有电荷，有其质量。
• Why doesn't it fly apart under the coulomb repulsion of like-charge elements ?
  为什么它不在同类电荷元的库仑排斥作用下散开呢？
• Electrostatic repulsion occurs between identical charges: －and－, or ＋and＋ .
  静电排斥发生于相同的电荷之间；与，或与。
• As the two charge distributions separate, leaving positive and negative sheaths .
  当两种电荷分布开始时，就留下正离子鞘和负离子鞘。
