1.【物】电子
1.a part of an atom that moves around the nucleuscenter and has a negative electrical charge
1.A fundamental rule which must be obeyed in placing two or more electrons in the orbits of an atom is the exclusion principle.
当两个或更多电子进入原子中的轨道时，必须遵循的基本规律是不相容原理。
2.The result was a flow of electrons around the edge of the material, like skaters circling the perimeter of an ice rink.
这样造成的结果就是一些电子不断绕着物质边缘流动，就像是滑冰的人在绕着整个场地一圈圈滑行。
3.When the total number of protons equals the total number of electrons, the body as a whole is electrically neutral.
当质子总数等于电子的总数时，这个物体就整体来说是电中性的。
4.On this basis, that the only particles in nature are electrons and protons, it seemed to me that the holes would have to be the protons.
在这个基础上，自然界中仅有的粒子是电子和质子，这告诉我这种空穴只能是质子。
5.The electrons carry the negative charge, the protons carry the positive charge. That was all that was needed.
电子携带负电荷，而质子携带正电荷，这就是所有需要的东西。
6.As far as a whole is concerned, the body is electrically neutral, when the total number of protons equals the total number of electrons.
当质子总数等于电子的总数时，这个物体就整体而言是电中性。
7.In the simplest setup, the size of the current reveals the density of electrons in the surface, allowing it to be mapped out.
在这个最简单的装置里，电流的大小表明了样品表面电子的密度，并能绘制出来。
8.Electrons, being waves as well as particles, produce a diffraction pattern when transmitted through a crystal.
电子和粒子同时产生波动，当电子穿过一块晶体时产生衍射模式。
9.Some of these electrons travel through the DNA forest and are fed into a device that measures their spin polarization.
其中的一部分电子穿过DNA“森林”后，注入一个可以测量其自旋极化率的仪器中。
10.Just as the planets revolve about the sun, planetary electrons are thought of as revolving about the nucleus.
正像行星围绕太阳转一样，行星般的电子被认为是围着原子核转的。
