Radiation
|
- Rayonnement
- Energy transmitted from a heat source to the air around it. radiators actually depend more on convection than radiation.
- Energy radiated in the form of waves or particles; photons.
- Radiation is a general term for energy which radiates out from a source and which can be particulate or part of the electromagnetic spectrum . it is more useful to specify the quality of the radiation, for example ionising radiation or non-ionising radiat
- Излучение; лучеиспускание; радиация
- Радиация, излучение
- Излучение; охлаждаемый излучением
- Systems, incorporated фирма «рэдиейш`н системз инкор- порейтед»
- In the context of optics, electromagnetic energy is released; the process of releasing electromagnetic energy.
- Waves of energy which are given off by some substances, especially radioactive substances comment: prolonged exposure to many types of radiation can be harmful. nuclear radiation is the most obvious, but exposure to x-rays, either as a patient being treated or as a radiographer, can cause radiation sickness. first symptoms of the sickness are diarrhoea and vomiting, but radiation exposure can also be followed by skin burns and loss of hair. massive exposure to radiation can kill quickly, and any person exposed to radiation is more likely to develop certain types of cancer than other members of the population.

- Излучение; радиация; лучеиспускание
- Радиация, излучение. в общем смысле — а) испускание или перенос энергии в виде электромагнитных волн или частиц; б) сама энергия, называемая также «лучистая энергия» (вмо). в радиационной физике радиация определяется более конкретно как: 1) электромагнитная или квантовая энергия (например, рентгеновские лучи и гамма-лучи); 2) корпускулярное излучение, состоящее из а) заряженных частиц (например, альфа-частиц, электронов,`протонов, дейтронов) и б) незаряженных частиц (например, нейтронов) (мэк, 2). на приводимой схеме дано примерное расположение спектра электромагнитной энергии с указанием типов радиации, рассмотренных в данном словаре. ю-14 ю"`3 ю-12 к)"11 ю-10 to" длина волны (м) ю"8 ю~7 ю"6. ю"5 1сг4 ю"3 1сг2 ю"1 1 космические рентгеновские- лучи лучи фотоны ультрафиолетовое излучение инфракрасное излучение радар гамма - лучи -минроволны л=3,8*ю~ =7,6*10 ~7 м спектр электромагнитного излучения
- The dissipation of energy from a source into its surroundings by the emission of waves or particles.
- A heat transfer process whereby heat is given off through electromagnetic radiation, usually infrared rays.
- Heat transfer by way of electromagnetic energy.
- The transfer of energy through propagation of electromagnetic waves. see also radiant energy. radiographic testing (rt): use of penetrating radiant energy in the form of x-rays, gamma rays, or neutrons for volumetric nondestructive testing of objects to provide images of the objects’ interiors. also called radiography; radiologic testing.

Rad, английский
- Exclamation or an adjective for something cool and exciting. example oh, rad! we have a four day weekend coming up!
- Radix — корень, основание (мат.)
- The rad is the old (non si) unit for absorbed dose , where 100 rad = 1 gray (gy). it follows that the rad represents an energy absorption of 0.01 joules / kg of absorbing medium.

- See: rapid application development. radial basis function (rbf) an alternative to the common linear functions underlying many modeling techniques such as (generalized) regression models and neural networks. in these models, the (preliminary) response is computed at each node as is the sum of the products between the weight vector and the input vectors. in a rbf model, the response is a (weighted) sum of the distance between the input points and the weights, which now represent "ideal" or kernel points. this can be applied in regression models using thin plate splines, neural networks, and recursive partitioning models. the distance function varies across models, but two common classes are decay models (thin plate splines and gaussian distance functions) and interval models (cart) where the function returns a 0/1 response. the distance function is sometimes scaled by a parameter called the "width``, which is somewhat analogous to the bias used in perceptrons. see also: cart, normalized radial basis function (nrbf).

- The special unit of absorbed dose. one rad is equal to an absorbed dose of 100 ergs/gram or 0.01 joule/kilogram (0.01 gray).
- (1) si symbol for radian. (2) radiation absorbed dose; unit of absorbed dose of ionizing radiation. one rad is equal to the absorption of 10–5 j (100 erg) of radiation energy per gram of matter. replaced by the gray (gy). radian (rad): measurement unit of plane angle subtending, in a circle, an arc equal in length to the radius.

Convection, английский
- Convection
- Currents created by heating air, which then rises and pulls cooler air behind it. also see radiation.
- The transfer of energy through a liquid or gas due to the motion of the medium.
- Конвекция
- Heat transmission, either natural or forced (by means of a fan), by currents of air control joint control-joint grouting the injection of grout into a control joint.
- The rising of heated surface air.
- Конвекция. установившееся внутреннее движе-. нне в каком-либо слое или воздухе, приводящее к вертикальному переносу теплоты, массы и т. д. (вмо). в воздухе конвекция чаще всего обусловлена плавучестью воздушных масс, контактирующих с нагретой поверхностью, что приводит к возникновению вертикального потока воздуха над поверхностью. конвекция может возникать также в результате воздушных течений и завихрений при встрече с механическими препятствиями, как, например, при прохождении воздуха над возвышенностью.
- The transfer of heat that results from motion of a fluid (gas or liquid).
- The transfer of heat energy through gasses and liquids by the amount and mixing of those fluids.
- Heat transfer by circulation within a medium such as a gas or a liquid.
- Heat transfer by circulation within a medium such as gas or a liquid.
- Type of heat transfer that takes place in a moving medium and is almost always associated with transfer between a solid (surface) and a moving fluid (such as air), whereby energy is transferred from higher temperature sites to lower temperature sites.3

- Radioactive can generally describe the property of a substance (or more accurately atomic nuclei) which are unstable and spontaneously decay (disintegrate) with the release of energy, the energy being either electromagnetic radiation , particulate or both
- Радиоактивный
- Generally, the property possessed by certain elements, such as uranium minerals, of spontaneously emitting alpha, teta, and/or gamma rays by the disintegration of the nuclei of their atoms.
- Atoms that are energetically unstable and decay to a stable condition by emitting radiation are said to be radioactive.
