Flashover
| Глоссарий терминов в области процессов горения и взрыва |
- Flashover, in contrast with backdraft, is a temperature driven event. a flashover is the rapid transition to a state of total surface involvement in a fire of combustible materials within an enclosure, the point between the growth phase and the fully developed phase of a fire. it requires that the fire’s energy is radiated back to the contents to produce a rapid rise in temperature and simultaneous ignition. a flashover occurs when there is a good supply of air that allows the accumulated unburned fuel to heat up to its auto ignition temperature.
- The transition phase in the development of a compartment fire in which surfaces exposed to thermal radiation reach ignition temperature more or less simultaneously and fire spreads rapidly throughout the space, resulting in full room involvement or total involvement of the compartment or enclosed space.

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.

- Переход от пластичного состояния к хрупкому
- A change in gait.
- Upward or downward change between gaits, speed, direction, or maneuvers.
- A move from one license, product, or license model to another. some examples of transitions are: a step-up to a higher edition; a move from on-premises to the cloud, or cloud to on-premises; or a move to or from a license model that is a hybrid of an online service and an on-premises product.
- An allowed path from one state to another.
- An animation effect that specifies how the display changes as a user moves from one item (such as a slide or web page) to another.
- In a statechart or activity diagram, a relationship between two states or action states or between a state and itself.
- Переход

Simultaneous, английский
- Одновременный
- A одновременный, синхронный component, interpreting
Development, английский
- Разработка; доводка
- Разработка; развитие; проявление
- Разработка; отработка; отладка; вариант; модификация
- Вариант; развитие (изобретения)
- 1. the process of growing, or of becoming larger and stronger, or more complex the development of the embryo takes place in the uterus. 2. something which happens and causes a change in a situation report any developments to me at once.
- N развитие cognitive ~ когнитивное развитие
- Министерство жилищного строительства и городского развития (сша)
- Property under construction, including preparation and installation of infrastructure
- Any computer code or materials, other than products, fixes or preexisting work, developed by microsoft or in collaboration with customer, which is provided to customer in the course of performance of a statement of services.
- Разработка (месторождения).
- Event, happening, occurrence
- Event, happening, occurrence something that has happened, or the act of making or improving something

Inhalation exposure, английский
For most chemicals in the form of vapors, gases, mists or fine particulates, inhalation (breathing) is the major route of entry. contaminants that enter the respiratory system through inhalation may harm the tissues of the respiratory tract or lungs. once inhaled into the body, chemicals can enter the bloodstream and circulate throughout the body, causing harm. inhalation exposure can be either chronic exposure or acute exposure.
Fully developed stage of a fire, английский
Fire has spread over much if not all the available fuel; temperatures reach their peak, resulting in heat damage. oxygen is consumed rapidly (nfpa 921).
