Определение ducting в Английский Язык Английский Язык словарь
The increase in range that an electromagnetic wave will travel due to a temperature inversion of the atmosphere The temperature inversion forms a channel or waveguide (duct) for the waves to travel in, and they can be trapped, not attenuating as would be expected from the radar equation
A series of aluminum pipes that run throughout the house to provide heating, and cooling for the house Additionally, oven exhausts, stove pipes, and bathroom ventilation runs through ducting
The propagation of UHF and microwave signals much farther than normal due to weather conditions, more frequently occurring in humid areas Ducting may occur when a layer of cold air forms under a layer of warm air, distorting the normal propagation of the radio or microwave signal
a bodily passage or tube lined with epithelial cells and conveying a secretion or other substance; "the tear duct was obstructed"; "the alimentary canal"; "poison is released through a channel in the snake's fangs"
-A channel for holding and protecting conductors and cables, made of metal or an insulating material, usually circular in cross section like a pipe Also referred to as Conduit
an enclosed conduit for a fluid a bodily passage or tube lined with epithelial cells and conveying a secretion or other substance; "the tear duct was obstructed"; "the alimentary canal"; "poison is released through a channel in the snake's fangs"
Specifically, a tube or passage that confines and conducts a fluid, as a passage for the flow of air to the compressor of a gas-turbine engine, a pipe leading air to a supercharger, etc
A cylindrical or rectangular "tube" used to move air either from exhaust or intake, and for distributing warm air from the heating plant to rooms, or air from a conditioning device or as cold air returns The installation is referred to as "duct work"
A pipe, tube, channel or any other necessary for conveying gases, liquids or solid units from one point to another The term is mostly identified with air-conditioning systems where the transfer of air is necessary This is accomplished through sheet-metal ducts The term is also applicable to under-floor duct systems for conveyance of telephone lines and other electrical conductors
In a glandular context, the manifold created in a compound gland between the tubules of individual simple gland cells and the exit point of the compound gland
A horizontal layer in the atmosphere in which temperature and moisture gradients are such that electromagnetic energy traveling within the layer is bent towards the earth's surface with a curvature equal to or greater than the earth's true curvature A strong temperature inversion and/or moisture lapse rate are necessary for the formation of a duct
