| Глоссарий по архитектуре и конструкциям |
The flow of gases in a chimney due to the difference in temperature and density between the gases within the chimney and the outside air. natural-draft boiler a boiler system in which a chimney is required to draw the products of combustion through the boiler or furnace. natural-draft chimney a chimney that draws the gases and smoke of combustion from a furnace because of the natural draft it develops; operates without auxiliary mechanical-draft equipment.

- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).
- Повышение температуры бетона ~ of truss высота фермы jet ~ высота подъёма горизонтальной неизотермической приточной струи, «всплывающей» над приточным отверстием

- Normal adult temperature varies among horses, but will usually range in degrees from 99.5°f to 100.5°f.
- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
- Measure of the intensity of particle motion in degrees celsius (°c) or degrees fahrenheit (°f) or, in the absolute scale, kelvin (k), where the increment of 1 k = 1 °c = 1.8 °f.

Combustion, английский
- Сгорание; горение
- Горение, сожжение
- Any chemical process that produces light and heat as either glow or flames.
- Burning, &c. (see spontaneous combustion.)
- Сгорание, сжигание, горение, возгорание
- Сгорание. химическая реакция, при: которой вещество соединяется с кислородом с выделением тепла: «горение». сгорание топлива, содержащего углерод и водород, считается полным, если цроисходит полное окисление этих двух элементов до углекислого газа и воды. неполное сгорание может привести к тому, что: 1) в золе остается значительное количество углерода; 2) часть углерода выделяется в виде окиси углерода; и 3) молекулы топлива реагируют с образованием ряда продуктов более сложного состава по сравнению с исходными молекулами топлива, и если эти продукты не сгорают, они выделяются в виде дыма. сгорание летучих продуктов может протекать более полно, если сверху на слой топлива подается так называемый вторичный воздух (воздух, пропускаемый через слой топлива, называется «первичным»). воздух сверх количества, теоретически необходимого для полного сгорания (избыточный воздух), следует подавать с минимальным избытком, чтобы` избежать неоправданных потерь тепла с дымовыми газами, слабой теплопередачи и окисления двуокиси серы в трехокись. перенасыщенное сгорание происходит в системе, где топливо подается сверху на раскаленный слой топлива. такая система характеризуется тенденцией к образованию дыма. тороидальное (кольцевое) сгорание происходит в системе, где в печи поддерживается вихревой поток; это увеличивает время пребывания топлива в печи и настолько улучшает горение, что дополнительной подачи воздуха, требуется мало или не требуется совсем. 40
- A combustion reaction involves a substance combining with an oxidizer, releasing a large amount of heat (exothermic) and produces a flame. the heat produced can make combustion self-sustaining. an oxidizer is a compound that takes electrons in a reaction and can promote or initiate combustion. oxygen and chlorine are examples of oxidizers. when oxygen is available in sufficient amounts, complete combustion occurs. if a hydrocarbon undergoes complete combustion, carbon dioxide and water vapor are produced. combustion reactions can be oxygen starved or can involve excess oxygen. in an oxygen starved combustion reaction, a combustion reaction has a limited oxygen supply and incomplete combustion occurs. in an environment of combustion in excess air, the amount of oxygen supplied to the combustion reaction is more than is needed for complete combustion and can lead to a hotter, faster burning fire.
- A chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.
- The chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.

Capillary flow, английский
The flow of moisture through a capillary pore system, as in concrete.
Streamline flow, английский
- The flow of a liquid or gas past a solid body in a manner so that the velocity of the fluid, at every point, does not change with time. streamline moderne, streamline modern a phase of art deco that emphasizes the contours that offer minimum resistance to fluid flow, resulting in emphasis on the horizontal aspects of design. usually characterized by curved end walls, rounded corners; glass block; flush windows; white or light-colored stucco walls; horizontal stainless-steel railings.
- Ламинарное течение. см. flow, laminar — ламинарное течение.
