Electron volt
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
A unit of energy commonly used to express the energy of x-rays. one electron volt is the energy gained by an electron when it is accelerated by a potential difference of 1 volt (1 ev = 1.60210 x 10-19 joule – si).

Electron, английский
- The electron is a low mass particle ( 1/1836 that of a proton ) with a unit negative electric charge. in simple terms the electrons are said to orbit around the nucleus of atoms . positively charged electrons can also exist, these being known as positrons
- Negatively charged particle of an atom.
- An elementary particle of an atom with a negative electrical charge and a mass of 1/1837 of a proton; electrons surround the positively charged nucleus of an atom and determine the chemical properties of an atom. the movement of electrons in an electrical conductor constitutes an electric current.
- An elementary particle of an atom with a negative electrical charge and a mass of
- One of the fundamental constituents of atoms. the electron is a very small negatively charged particle with a rest mass of approximately 1/1836 that of the hydrogen atom, or 9.107 x 10-28 gm. it has an electric charge of 4.802 x 10-10 statcoulomb (the electrostatic unit of charge). electrons appear to be uniform in mass and charge.
Electron affinity, английский
The amount of energy absorbed or given off when an atom accepts an electron.

Electron capture, английский
Electron capture (rt), английский
A mode of radioactive decay in which a bound electron is captured by the nucleus of the same atom, producing a vacancy in an inner emission of characteristic x-rays or auger electrons.
Difference, английский
- Disagreement, inequity, contrast, dissimilarity, incompatibility
- Разница; разность
- An important army term, meaning firstly the sum to be paid by officers when exchanging from the half to full pay; and, secondly, the price or difference in value of the several commissions.

Oersted (mt), английский
A unit of field strength that produces magnetic induction designated by the letter “h.” the oersted is numerically equal in the air or in a vacuum. oersted (h) refers to the magnetizing force tending to magnetize an unmagnetized body, and gauss refers to the field (b) so induced in the body.
Milliampere (rt), английский
A unit of electrical current equal to one-thousandth of an ampere.
