- Conduction
- The direct transfer of heat energy through a material.
- The transfer of energy through a solid without motion of the conducting solid as a whole. steady-state conduction calls if the temperature at each point is independent of time. unsteady or transient conduction situations changes with time (time dependant)
- The process of passing heat, sound or nervous impulses from one part of the body to another
- Проводимость; электрическая проводимость; электропроводность
- The transfer of heat energy through matter.
- The transfer of heat energy in materials (usually solids) via molecular scale vibrations and collision interactions.
- Heat transfer to another body or within a body by direct contact.
- Heat transfer occurring when more energetic particles collide with — and thus impart some of their heat energy to — adjacent less energetic (slower moving) particles. this action is passed on from one atom (or free electron) to the next in the direction of cooler regions. thus, heat always flows from a warmer to a cooler region.1 conductivity, thermal (k): material property defining the relative capability to carry heat by conduction in a static temperature gradient. conductivity varies slightly with temperature in solids and liquids and with temperature and pressure in gases. it is high for metals (copper has a k of 380 w·m–1·k–1) and low for gases and porous materials (concrete has a k of 1.0 w·m–1·k–1).3 682 infrared and thermal testing

Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.
- An expression of thermal energy density. how hot or cold an object is.
- The measure of the intensity of heat that a substance possesses.
- Температура
- Температура тмр test methods and procedures методы проведения испытаний и последовательность их проведения тмр theodolite measuring point кинотеодолитная станция
- Temperatura, fiebre
- The condition attained when the wetted wick of a wet-bulb thermometer has reached a stable and constant temperature when exposed to moving air in excess of 900 ft (274.3 m) per minute.
- 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
- Температура ~ of adiabatic saturation температура адиабатического насыщения
- 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.
- Temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. ampere (a): si unit of electric current. ampere per meter (a·m–1): si derived unit of magnetic field intensity. the measurement 1 a·m–1, for example, describes a current of 1 a flowing through a coil that is 1 m in diameter. compare oersted. ampere turn (at): in magnetic particle testing, unit for expressing the magnetomotive force required for magnetization using a coil in terms of the product of the number of coil turns and the current in amperes flowing through the coil. amplitude, echo: in ultrasonic testing, the vertical height of a received signal on an a-scan, measured from base to peak for a video presentation or from peak to peak for a radio frequency presentation.
- Measure of the intensity of particle motion in degrees celsius (°c), degrees fahrenheit (°f) or, in the absolute scale, kelvin (k) or degrees rankine (°r). an increment of 1 k = 1 °c = 1.8 °r = 1.8 °f. compare heat.

Электрическая, русский
Электропроводность, русский
- (проводимость) , способность веществ проводить электрический ток, обусловленная наличием в них подвижных заряженных частиц (носителей заряда) - электроионов, ионов и др., а также физическая величина (v), количественно характеризующая эту способность. величина 1/v называется удельным электрическим сопротивлением.
- Свойство вещества проводить под действием не изменяющегося во времени электрического поля не изменяющийся во времени электрический
- Способность веществ проводить электриче-ский ток под действием внешнего электрического поля. если проводи-мость обеспечивается электронами (например, в металлах), то соответ-ствующие вещества называются проводниками первого рода, а если но-сителями тока являются ионы (например, в растворах электролитов), то соответствующие вещества называются проводниками второго рода.
