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.
Synchronous, английский
- Синхронный
- A data signal that is sent along with a clock signal. a system in which events, such as signals, occur at evenly spaced time durations. opposite of asynchronous. t
Fluorescence, английский
- Emission of light of particular wavelength, as a result of absorption of light at shorter wavelength. it is a property of some materials; each material has a specific wavelength of absorption and emission.
- Luminescence arising from irradiation with light
- The emission of visible light from a substance (such as a phosphor) as the result of, and during, the absorption of radiation of shorter wavelengths.
- The sending out of light from a substance which is receiving radiation
- Certain diamonds exhibit colored luminescence (usually blue) when exposed to strong sunlight or ultraviolet light. all you need to know about diamond fluorescence.
- Emission of visible light by a material such as diamond when it is simulated by higher energy x-rays, ultraviolet radiation or other forms of radiation. fluorescence continues only as long as the material is exposed to the radiation. strong or very strong fluorescence may make a diamond appear milky or oily especially in sunlight.
- Fluorescence happens when a diamond is exposed to ultraviolet light, it may emit a soft glow of white-ish, blue-ish or yellowish light. diamond grading reports will most often note whether a diamond has fluorescence, however, is not considered a grading factor, only a characteristic of that particular diamond.
- The property by which some minerals and some organic substances, when exposed to ultra¬violet radiations, emit a light of a color differing from their own, like the blue-white light emitted by scheelite.
- Emission of electromagnetic radiation, usually as visible light, that is caused by the flow of energy into the emitting body. the emission ceases abruptly when the excitation ceases. fly: the short, waste fibers that are released into the air in textile processing operations such as picking, carding, spinning, and weaving.
- The process in which molecules or matter absorb high energy photons and then emit lower energy photons. the difference in energy causes molecular vibrations.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer wavelength). in visual testing, fluorescence is typically a response to ultraviolet radiation.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence in ndt may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed. see also spectrofluorometer.
- Luminescent phenomenon exhibited by some substances where higher energy electromagnetic waves are absorbed and reemitted as lower energy waves. the emission ceases as soon as the exciting energy is removed. different from phosphorescence, which will continue to emit after the exciting energy is removed. in magnetic particle testing, pigments coating the magnetic particles are excited by invisible uv-a radiation and emit visible light.
