An atom or a group of atoms that has an electric charge. Positive ions, or cations, are formed by the loss of electrons; negative ions, or anions, are formed by the gain of electrons. See Note atcharge. The American Heritage® Student Science Dictionary, Second Edition. Copyright © ...

apositive ions (cations)are drawn towards the negative electrode,where they receive electrons from the electron-rich cathode and neutral atoms or molecules are formed. 正面离子(正离子)被画往消极电极,他们从富有电子的负极接受电子和中立原子或者分子被形成。[translate]...
It is evident that negative ions are tremendously important to our health. Negative ions have the power to help the body to heal itself. Medical research has also proven that 90% of the eye diseases are the result of hypoxia (lack of oxygen). When oxygen and water supply to the eyes is...
There were, however, always present several light negative ions, which had the excess energies found by Arnot and Milligan (1936 b ) with Hg-. The conditions under which these were formed led us to suppose that they were produced by bombardment of the metal surfaces by mercury positive ions...
Positive and negative ions formed by attachment processes (p 489-494) Californium-252 plasma desorption mass spectra have been run on a series of typical lipids found in skin, including a fatty acid, a methyl and wax ester, a mono-, di- and triglyceride and an anhydride, in a effort to...

5.In the region where the corona exists, large numbers of positive and negative ions are formed.在存在电晕的区域,形成了大量正离子和负离子。 6.In some way, positive and negative ions are developed in a thunderstorm.在雷雨中,正离子和负离子以某种方式形成。
It should be understood that this discussion as related to negative ions is tentative due to the fact that many more rate constants are needed to provide a quantitative answer.It is also attempted to postulate the existence of condensation embryos formed by gas-to-particle conversion induced by ...
Multilayered samples of ten binary metal systems of different overall compositions were bombarded at 77 K by 400 keV Kr+-ions. All systems have positive heats of formation, which means that in thermal equilibrium the miscibility in the solid state is small. The samples were analysed by in situ...
