Diffraction (rt)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
The scattering of incident radiation from the regularly spaced atoms in crystals or complex molecules such that interference between the scattered waves results in a pattern of maxima and minima in the intensity of the scattered radiation.

Diffraction, английский
- The "spreading" of waves into the lee of obstacles such as breakwaters by the transfer of wave energy along wave crests. diffracted waves are lower in height than incident waves.
- Дифракция
- Deviation of the direction of propagation of a radiation, determined by the wave nature of radiation, and occurring when the radiation passes the edge of an obstacle.
- A wave property which creates deviation from a straight line when the beam passes near an edge of an opaque object. deviation of part of a beam, determined by the wave nature of radiation and occurring when the radiation passes the edge of an opaque obstacle.
- Light curves or travels around small circular objects.
- The changing of direction (bending or spreading) that occurs when a light wave interacts with an opening or barrier
- (1) in acoustics, the reflection of a wave front when passing the edge of an ultrasonically opaque object. (2) in radiation technologies, a special case of scatter, where coherently scattered photons undergo interference or reinforcement, resulting in patterns indicative of the scattering medium. see also xray diffraction.
- (1) в акустике - отражение волнового фронта при прохождении края непрозрачного для ультразвука объекта. (2) в радиационных технологиях - особый случай рассеяния, когда когерентно рассеянные фотоны подвергаются интерференции или усилению, что приводит к образованию структур, указывающих на рассеивающую среду. см. также дифракция рентгеновских лучей.
- (1) in radiographic testing, special case of scatter, where coherently scattered (full intensity is retained) photons undergo interference or reinforcement, resulting in patterns indicative of the scattering medium. see also x-ray diffraction. (2) in ultrasonic testing, deflection of a wavefront when passing the edge of an ultrasonically opaque object.15
- Deflection of a wavefront when passing the edge of an ultrasonically opaque object.7,22
Diffraction (ut), английский
The deflection of a wave front when passing the edges of an obstacle.

Diffraction grating, английский
- An array of fine, parallel, equally-spaced reflecting or transmitting lines that mutually enhance the effects of diffraction to concentrate the diffracted light in a few directions determined by the spacing of the lines and by the wavelength of the light
- An array of fine, parallel, equally spaced reflecting or transmitting lines that mutually enhance the effects of diffraction to concentrate the diffracted light in a few directions determined by the spacing of the lines and by the wavelength of the light.
- Дифракционная решетка
Scattering, английский
- Утруска
- Intrinsic fiber losses caused by undissolved particles, boundary roughness, and intrinsic material losses
- Loss of light that is scattered off atoms in different directions, so it escapes from the fiber core. a major component of fiber attenuation.
- Рассеяние. процесс, в ходе которого происходит изменение направления или энергии падающей частицы или радиации, вызываемое столкновением с другой частицей или системой частиц (мос, 5). рассеяние ми — рассеяние электромагнитного излучения сферическими частицами при отсутствии четкой зависимости между размером частиц и длиной волны излучения. оно имеет большое значение для исследований по загрязнению атмосферного воздуха. свет интенсивно рассеивается частицами диаметром около 0,1—1 мкм; происходящее при этом снижение видимости является функцией квадрата радиуса частиц. рассеяние рэлея — рассеяние частицами, радиус которых меньше ую длины волны излучения (например, рассеяние света молекулами кислорода и азота в воздухе).
- Reflection of ultrasonic waves by small discontinuities or surface irregularities.
- Uncontrolled reflection of ultrasonic waves by small discontinuities or surface irregularities.7
Interference, английский
- Effect caused by the introduction of unwanted electrical signals into an electrical circuit. in cctv this results in "noise" in the signal or picture, which disrupts the picture.
- Extraneous energy which tends to interfere with the reception of the desired signals.
- Disturbances of an electrical or electromagnetic nature that introduce undesirable
- “artifactual increase or decrease in apparent concentration or intensity of an analyte due to the presence of a substance that reacts nonspecifically with either the detecting reagent or the signal itself.” [clsi]
- Signal
- Столкновение прав (заявляемых или патентных); приоритетный спор
- A scrambling of the content of signals by the reception of desired signals.
- Disturbances of an electrical or electromagnetic nature that introduce undesirable responses in other electronic equipment.
- A range of phenomena associated with the superposition of waves
- For light, the way that waves add together, depending on their phase. constructive interference occurs when the waves are in phase and their amplitudes add. destructive interference occurs when the waves are 180 degree out of phase and their amplitudes cancel.
- N интерференция interfix n интерфикс
- The static and other noises sometimes heard over the phone line.
- Столкновение одновременно заявляемых прав на патент
- Distortion of a light wave due to interaction with another wave
- A proceeding, conducted before the patent trial and appeal board, to determine priority of invention between a pending application and one or more pending applications and/or one or more unexpired patents under pre-aia u.s. patent law.
- A proceeding conducted before the board of patent appeals and interferences to determine the priority of invention between a pending application and one or more pending applications and one or more unexpired patents.
- The negative effect of a learners first language(s) on the learning of a target language.
- Помехи, наводки

Radiographic technique (rt), английский
The selection of those radiographic factors such as kilovoltage, milliamperage, type of film and screen, distance, and exposure time to render the best possible radiographic sensitivity.
Coherent scatter, английский
- The result of compton scattering in which the electron receives none of the energy from the primary radiation. the resultant scattered radiation is of the same energy as the incident beam.
- Form of scatter where no energy is lost.
- Форма рассеяния, при которой энергия не теряется.
