Fog (rt)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
A general term used to denote any increase in the optical density of a processed film caused by anything other than the direct action of image-forming radiation.

Fog, английский
- Minute water droplets suspended in the air that reduce surface visibility to less than 1000m. fog is cloud on the ground.
- A hydrometeor consisting of numerous minute water drop- lets and based at the surface; droplets are small enough to be suspended in the earth's atmosphere indefinitely.
- Туман
- For our guidance
- Туманный горн - устройство для подачи звуковых сигналов в условиях с ограниченной видимостью
- A mist at sea, consisting of the grosser vapours floating in the air near the surface of the sea. the fog of the great bank of newfoundland is caused by the near proximity of warm and cold waters. the air over the gulf stream, being warmer than that over the banks of newfoundland, is capable of keeping much more moisture in invisible suspension; and when this air comes in contact with that above the cold water, it parts with some of its moisture, or rather holds it in visible suspension. there are also dry fogs, which are dust held in suspension, as the so-called african dust, which often partially obscures the sun, and reddens the sails of ships as they pass through the north-east trades.
- See: forecast generator.
- Surface cloud with visibility less than 1,000m.
- In film radiologic testing, increase of film density caused by sources other than from the intended primary beam exposure. heat, humidity, pressure, and scatter radiation can all cause fogging of the film.
Fog, английский
Fog, английский
Fog (-át), венгерский
Fog (on film - unintentional), английский
An accidental "image veiling" through light leaks or chemical action. one of the more serious technical nightmares that help to make film insurance nearly prohibitive.
Fog - advection, английский
A form of fog caused by the movement (advection) of moist air over a colder surface which cools the air to its dew point. the resulting condensation of water vapour causes a ground-level cloud to form. moist air moving over cold lake or ocean waters or moving over an ice or snow surface is the most common
Fog - frontal or pre-frontal, английский
A form of fog associated with weather fronts caused by the cooling of moist air to its dew point in the zone along and ahead of the front.
Fog - radiation, английский
A form of fog caused by the cooling of moist air to below its dew point by the process of heat radiation. radiation fog usually forms near the surface at night under clear skies and light wind conditions. also known as ground fog.
Fog - steam, английский
A form of fog caused by the advection of cold air over a warm water surface or a very saturated soil surface, giving the impression of rising steam. common over large lakes and near-shore ocean areas during the cold season.
Fog bank, английский
A dense haze with at least one clearlydefined edge, looking like a thick cloud resting on the horizon. often the precursor of wind, especially in high latitudes.
Fog buoy, английский
A floating device towed behind a leading vessel so that another, immediately astern, will be able to keep station in bad visibility. also called towing spar.
Fog curing, английский
The curing of concrete products in a room having very high humidity (achieved by the atomization of water). also
Fog density, английский
Fog density (rt), английский
Fog disdrometer, английский
Fog dispersing/dissipating slowly as a result of solar radiation, английский
Fog filter, английский
One of many special camera filters that introduce image diffusion, smearing of highlights, and light-ening of dark areas. the "fog," however, neither moves nor increases with distance. for those, use a . . .
Fog hardening, английский
Закалка в парах жидкости
Fog investigation and dispersal operation, английский
(system) аэродромная туманорассеивающая установка
Fog lamp, английский
Supplementary lamp to provide illumination forward (or rearward) in conditions of poor visibility,
|
Dose or radiation dose, английский
A generic term that means absorbed dose, dose equivalent, etc. and represents the total amount of radiation received during the applicable period of exposure.
Radiation damage (rt), английский
A general term for the alteration of properties of a material arising from radiation exposure to x-rays, gamma rays, neutrons, heavy-particle radiation, or fission fragments in nuclear fuel material.
