您要查找的是不是:
- Their energy is high enough to remove orbital electrons from atoms, thus giving rise to positively charged ions and negatively charged electrons. 它们的高能量可把其他原子内的电子撞出原子之外,产生带正电荷的离子及带负电荷的电子。
- positively charged electron 阳电子
- In particular, no evidence at all was found for a positively charged equivalent of the electron. 尤其没有发现一种与电子相当的正电荷存在的任何证据。
- A positively charged electrode, as of an electrolytic cell, a storage battery, or an electron tube. 阳极,正极电解电池、蓄电池或电子管的正电电极
- A positively charged electrode,as of an electrolytic cell,a storage battery,or an electron tube. 阳极,正极电解电池、蓄电池或电子管的正电电极
- A stable, positively charged subatomic particle in the baryon family having a mass1, 836 times that of the electron. 质子重子族群中一种稳定的带正电的中子核,质量为电子的1,836倍
- Prior to Rutherford, Eugene Goldstein had observed canal rays, which were composed of positively charged ions.After the discovery of the electron by J.J. 其中一个大统一理论的预言是,构成通常物质的大部分质量的质子能自发衰变成诸如反电子之类更轻的粒子。
- To homogenize the surface potential, an effective method is to scan the specimen with an electron beam (e-beam) that makes the specimen positively charged. 为了使表面电位均匀化,一个有效的方法是使用正带电电子束扫描样品表面。
- This charge is a positive charge. 这个电荷是正电荷。
- The atom that loses the electron becomes a positively charged ion, and the receiving atom becomes negatively charged, so the two ions become bonded by a strong electrostatic force. 失去电子的原子带有正电成为正离子,得到电子的原子带负电成为负离子,然后这两个离子被强烈的静电力所结合。
- The plate of the capacitor having lost some electrons will be positively charged. 失去一些电子的电容器板就会带正电。
- The protons, bring positively charged, repel one another by virtue of their electrostatic interactions. 质子带正电,由于静电的相互作用而彼此排斥。
- The remainder of the atom from which one or more electrons are removed must be positively charged. 如果从原子中移走一个或多个电子,则该原子的其余部分必定带正电。
- All positively charged species in solution must be balanced by equivalent numbers of negatively charged species. 溶液中所有带正电荷物质必须被等量的带负电荷物质所平衡。
- An electron has a negative charge,a proton has a positive charge. 电子带负电荷,质子带正电荷。
- Electrostatic attraction will play a major role in the absorption of viruses to positively charged surfaces. 静电吸引在病毒吸附到带正电荷的表面中起主要的作用。
- The fur must have a positive charge. 毛皮必定带有正电荷。
- The protons,bring positively charged,repel one another by virtue of their electrostatic interactions. 质子带正电,由于静电的相互作用而彼此排斥。
