Telecommunications, английский
- Передача и прием электромагнитных сигналов или любой информации по проводам, радио- и другим каналам
- (радио) связь; средства (дальней) связи
- Communicating over a distance. use of wire, radio, optical or other electromagnetic channels to transmit or receive signals for voice, video and data communications.
- The transmission and reception of signals (such as electrical or optical) by wire, optical fiber, or electromagnetic means. telegraphing, show-through on a decorative material covering a wall, etc., irregularities, imperfections, or patterns of an inner layer which are transmitted to the surface so that they become visible.
- Communicating by sending voice, data or images over networks that might involve telephone lines, satellites, and the radio spectrum. see telecommunications network.
Protrusion, английский
According to the tia, the fiber optic is either polished even with the endface or has a positive or negative protrusion, i.e., “sticks out” or is recessed
Undesirable, английский

Electromagnetic, английский
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
Nondestructive, английский
- Неразрушающий
- Неразрушающий (об испытаниях и т.п.)
Ultraviolet, английский
- Electromagnetic radiation at wavelengths shorter than the violet end of visible light
- Ultraviolet. the electromagnetic radiation with wavelengths shorter than about 400 nm and not visible to the human eye.
- Ультрафиолетовый
- Invisible electromagnetic radiation defined between 100 and 380nm.
- The part of the electromagnetic spectrum that falls just below visible violet. ultraviolet (uv) coating – a coating that blocks out uv radiation up to 380+ nanometers.
- Electromagnetic radiation in the wavelength range of 4 to 400 nanometers.
Irradiance, английский
- The density of the luminous flux which is incident on a surface.
- Интенсивность излучения
- The direct, diffuse, and reflected solar radiation that strikes a surface. usually expressed in kilowatts per square meter. irradiance multiplied by time equals insolation.
- The direct, diffuse, and reflected solar radiation that strikes a surface. usually
- Power of electromagnetic radiant energy incident on or radiated from the surface of a given unit area. compare radiance.
- Radiant power falling upon a known surface area at a given angle. compare radiance. see also radiometer. ishiharatm plates: trade name for a kind of pseudoisochromatic plates, used for color differentiation vision testing.
- Total radiant power, in watts per square meter (w/m2), falling upon a known surface area at a given angle.
- Total radiant power, in watts per square meter (w/m2), falling on a known surface area at a given angle. compare radiance. see also radiometer. irradiance, effective: measure of spectrally weighted radiant power in watts per meter-squared, as determined with a sensor whose responsivity replicates some desired action spectrum. compare irradiance; irradiance, spectral. irradiance, spectral: measure of energy emitted by a radiation source as function of wavelength. units of spectral irradiance are watts per square meter per nanometer (w·m–2·nm–1) and are often plotted versus wavelength. see also spectral power distribution. ishihara plate: trade name for a kind of pseudoisochromatic plate used for color differentiation vision testing.
- Radiant power falling upon a known surface area at a given angle. in nondestructive testing, the unit for irradiance of a uv-a source is microwatt per centimeter squared (?w·cm–2) and maximum irradiance occurs when the source and surface are perpendicular.
- Radiometer. j
Radiometer, английский
- An instrument, distinct from a photometer, to measure power (watts) of electromagnetic radiation.
- An instrument designed to measure the intensity of radiant energy.
- Device used to measure irradiance or radiant energy of specified frequencies. different radiometers exist for different frequencies. in nondestructive testing, radiometers are used to measure uv-a output, or leaked visible light, in microwatt per square centimeter (?w/cm2). see also irradiance. compare photometer.
- Device used to measure irradiance. in nondestructive testing, radiometers are used to measure uv-a output, or leaked visible light, in microwatt per square centimeter (?w·cm–2). see also irradiance. compare photometer.
- Device used to measure irradiance. in nondestructive testing, radiometers are used to measure uv-a output or visible light in si units of watts per square meter (w/m). used in fluorescent penetrant and magnetic particle testing to measure output of excitation sources. see also irradiance. compare photometer.

Ground pressure, английский
- Weight of a vehicle under specific conditions, transmitted to the ground and computed for the per-unit area of contact between ground and wheels or track shoes (26).
- The pressure to which a rock forma¬tion is subjected by the weight of the superimposed rock and rock material or by diastrophie forces cre¬ated by movements in the rocks forming the earth`s crust. such pressures may be great enough to cause rocks having a low compressional strength to de¬form and be squeezed into and close a borehole or other underground opening not adequately strength¬ened by an artificial support, such as casing or timber. also called rock pressure. compare bot-tomhole pressure 3.
Falling wedge, английский
Wedge used to throw a tree in the desired direction (24).
