Fluorescent (rt)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
The emission of electromagnetic radiation by a substance as the result of the absorption of electromagnetic or corpuscular radiation having greater unit energy than that of the fluorescent radiation. fluorescence is characterized by the fact that it occurs only so long as the stimulus responsible for it is maintained. the characteristic x-radiation emitted, as a result of absorption of x-rays of higher frequency is a typical example of fluorescence. property of emitting visible light as the result of and only during, the absorption of radiant energy from some other source (i.e., black light).

Fluorescent, английский
- Флуоресцирующий; флуоресцентный (о надписи)
- U-lamp a tubular lamp whose bulb has a 180° bend at the center,
- Having the property to produce fluorescence.
- The ability of certain materials to absorb energy and then immediately release that energy in the form of light
Fluorescent antibodies, английский
Флюоресцирующие антитела применяются в микробиологической диагностике.
Fluorescent antibody (fa) techniques, английский
Suite of assays that use a fluorescently labeled antibody to bind to and so make an antigen easy to visualize

Fluorescent discharge tube, английский
Fluorescent dye penetrant (pt), английский
A highly penetrating liquid that fluoresces when subjected to ultraviolet or black light, used to produce luminous indications of surface flaws or discontinuities.
Fluorescent enzyme immunoassay (feia), английский
Eia in which the substrate is a fluorogen that becomes fluorescent following reaction with the enzyme
Fluorescent filters, английский
Filters designed to compensate for weak red and excessive green wavelengths in typical fluorescent light sources. fld and flb filters can tame some of the more commonly used tube types. tip: for the new pro, tests are advisable.
Fluorescent intensifying screen, английский
Fluorescent lamp, английский
- A lass tube filled with mercury gas and coated on its inner surface with phosphors. when the gas is charged with an electrical current, radiation is produced which in turn energizes the phosphors, causing the phosphors to glow.
- A low-pressure electricdischarge lamp; ultraviolet-light radiation is generated by the passage of an arc through mercury vapor; the inner surface of the lamp tube is coated with a phosphor which absorbs the ultraviolet and converts some of it into visible light. flow pressure 424 flue lining fluorescent lamp
- Commonly and improperly designates an electric lamplike device emitting ultraviolet radiations or black light.
- A glass globe or tube the inner surface of which is coated with a fluorescent substance that produces visible light when excited by an electrical current.
Fluorescent lamp., английский
Fluorescent lamps, английский
Lamps which emit fluorescent light, usually generated by irradiation of a phosphor with light from an electric gas discharge
Fluorescent light, английский
- Light produced by a fluorescent lamp. see fluorescent lamp.
- A form of lighting that uses long thin tubes of glass which contain mercury vapour and various phosphor powders (chemicals based a glossary of renewable energy all those technical terms can make renewable energy systems difficult for many people to understand. this glossary aims to cover all of the most commonly used terms, as well as a few of the more specific terms. www.ata.org.au renew 110 89 on phosphorus) to produce white light. see also compact fluorescent lamp.
Fluorescent lighting, английский
A fluorescent lamp is a gas-filled glass tube with a phosphur coating on the inside. gas inside the tube is ionized by electricity which causes the phosphur coating to glow. normally with two pins that extend from each end.
Fluorescent lighting fixture, английский
A luminaire, usually complete with fluorescent lamps, sockets, ballast, reflector, and a louver or diffusing medium. fluorescent-mercury lamp
Fluorescent magnetic particle inspection (mt), английский
The inspection process employing magnetic materials which have been coated with a material that fluoresces when activated by light of suitable wavelength.
Fluorescent magnetic particles, английский
Fluorescent magnetic-particle inspection, английский
Fluorescent paint, английский
Fluorescent particle, английский
Magnetic particle coated with pigment that fluoresces when excited with uv-a radiation. testing with fluorescent particles is performed under low ambient lighting and controlled ultraviolet radiation. compare dual-use particle; visible particle.
Electromagnetic, английский
Absorption, немецкий
Corpuscular, английский
Fluorescence, английский
- Emission of light of particular wavelength, as a result of absorption of light at shorter wavelength. it is a property of some materials; each material has a specific wavelength of absorption and emission.
- Luminescence arising from irradiation with light
- The emission of visible light from a substance (such as a phosphor) as the result of, and during, the absorption of radiation of shorter wavelengths.
- The sending out of light from a substance which is receiving radiation
- Certain diamonds exhibit colored luminescence (usually blue) when exposed to strong sunlight or ultraviolet light. all you need to know about diamond fluorescence.
- Emission of visible light by a material such as diamond when it is simulated by higher energy x-rays, ultraviolet radiation or other forms of radiation. fluorescence continues only as long as the material is exposed to the radiation. strong or very strong fluorescence may make a diamond appear milky or oily especially in sunlight.
- Fluorescence happens when a diamond is exposed to ultraviolet light, it may emit a soft glow of white-ish, blue-ish or yellowish light. diamond grading reports will most often note whether a diamond has fluorescence, however, is not considered a grading factor, only a characteristic of that particular diamond.
- The property by which some minerals and some organic substances, when exposed to ultra¬violet radiations, emit a light of a color differing from their own, like the blue-white light emitted by scheelite.
- Emission of electromagnetic radiation, usually as visible light, that is caused by the flow of energy into the emitting body. the emission ceases abruptly when the excitation ceases. fly: the short, waste fibers that are released into the air in textile processing operations such as picking, carding, spinning, and weaving.
- The process in which molecules or matter absorb high energy photons and then emit lower energy photons. the difference in energy causes molecular vibrations.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer wavelength). in visual testing, fluorescence is typically a response to ultraviolet radiation.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence in ndt may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed. see also spectrofluorometer.
- Luminescent phenomenon exhibited by some substances where higher energy electromagnetic waves are absorbed and reemitted as lower energy waves. the emission ceases as soon as the exciting energy is removed. different from phosphorescence, which will continue to emit after the exciting energy is removed. in magnetic particle testing, pigments coating the magnetic particles are excited by invisible uv-a radiation and emit visible light.
