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.
Hydrocarbon, английский
- Углеводород
- Углеводород. органическое соединение, содержащее только углерод и водород. атомы углерода могут быть соединены либо в незамкнутую цепь, простую или разветвленную (см. alkane; alkene — алкан; алкен), либо в замкнутые кольца. существует два типа углеводородов с замкнутой цепью: алициклические соединения, которые состоят из трех или более углеродных атомов, соединенных в замкнутое кольцо, и свойства которых аналогичны свойствам соединений такой же молекулярной массы, но с незамкнутой цепью, и ароматические соединения. основой молекулярной структуры ароматических соединений является бензол, простейшее соединение этого ряда, который содержит шесть атомов углерода, соединенных тремя простыми и тремя двойными углерод-углеродными связями. если такие соединения содержат два и более ароматических кольца, они называются полицикличе-гкими; используется также термин «многоядерные» (например, многоядерный ароматический углеводород); общепринятое сокращение полициклических ароматических углеводородов — пау. основными компонентами бензина и других нефтепродуктов являются углеводороды с открытой цепью. эти соединения не считаются опасными для здоровья, даже при тех концентрациях, в которых они присутствуют в городском 74
- Углеводороду.
- Chemical compound that contains only, or principally, carbon and hydrogen. the principal constituent of liquid fossil fuels.
- A compound of hydrogen and carbon of which petroleum products are typically examples. petroleum oils are generally grouped into two parts: naphthenics possess a high proportion of unsaturated cyclic molecules; paraffinics possess a low proportion of unsaturated cyclic molecules.
- A compound composed of carbon and hydrogen, the basic element of countless organic compounds and the principal constituents of petroleum. hydrocarbons in petroleum fall into three basic categories: the straight-chain paraffins (aliphatic); the cyclic (ring) chain (naphthenic) and the cyclic chain (aromatic).
