| Словарь терминов и сокращений в авиации |
- Относительная плотность
- For a given void ratio of soil, the ratio between: (a) the difference between the void ratio of the soil in its loosest state and the given ratio and (b) the void ratio in the loosest state minus the void ratio in the densest state.
- The ratio of the density of a substance to the density of a standard substance at the same temperature and pressure. for liquids and solids the standard substance is usually water, and for gases, it is air.

Density, английский
- Stand density
- As applied to timber, density is the mass of wood substance and moisture enclosed within a piece expressed in kilograms per cubic meter. as the mass will vary dependant on the amount of moisture in the piece, density is often expressed at a specified mois
- The weight per unit volume of a substance.
- The ability of a material to absorb light; the darker it is, the higher the density.
- The mass of a unit volume of a substance. its numerical value varies with the units used.
- Плотность

- A measure of how tightly packed the atoms of a substance are. measured in grams per cubic centimeter. varies by the mineral or substance. for example, gold has a high density, while quartz has a low density. see also "specific gravity."
- The weight of cargo per cubic foot or other unit.
- In general terms, the measure of the light-gathering power of silver or dye deposits in film. also, the buildup of silver that creates the image in film and paper. a "dense" negative or slide is more opaque than a "thin" one. there is an ideal density for film, one that yields good prints or slides; too little density usually means that the film was underexposed (or underdeveloped), too much means its been overexposed (or overdeveloped).

- Плотность вязания
- The weight of a body in comparison with its bulk.
- The weight of water divided by the amount of space it occupies. this is determined by the combined effect of temperature, salinity, and atmospheric pressure. cold, salt-laden water is denser than warmer, fresher water and will sink below it. see density levels.
- The ratio of the mass of any volume of a substance to the mass of an equal volume of a standard substance. for example, water is used as the standard substance to which the ratio of a quantity of a drill mud is compared.
- Having the quality of being dense, hard, or compact.
- Плотность; интенсивность; степень

- Quantity or mass per unit volume, unit area or unit length. energy density is the amount of energy per unit volume or mass (for example, the heating value of a litre of oil). power density is typically understood as the capacity deliverable of solar, wind, biomass, hydropower or ocean power per unit area (watts/m). for batteries the capacity per unit weight (watts/kg) is used. direct solar energy - see solar energy
- The mass of the substance per unit volume, usually specified at standard temperature and pressure
- The mass of liquid per unit of a substance at 15°c.
- Mass per unit volume.
- (1) in radiographic testing, degree of x-ray film darkness as a result of exposure as measured with a densitometer. (2) material property of mass per unit volume.
- Material property of mass per unit volume.
- Mass per unit volume, measured in kilograms per cubic meter (kg·m–3).
- Reference to the weight of foam used for seat and back cushions; either low density or high density.
Density, французский

Density gradient, английский
- Градиент плотности; градиент концентрации
- The change in density of a radiographic film at a particular film density per unit change in the logarithm of the exposure received by the film. the maximum density gradient of a film is usually called gamma.
Density identification area, английский
Density levels, английский
Ocean waters can be divided into three layers, depending on their density. at the top is the surface or mixed zone. this is unstable due to atmospheric interference. for example, evaporation could increase its salinity, or a cold front could reduce its temperature. in the middle is a transition zone known as the pycnocline layer (greek pycno = dense + cline = slope). this forms a barrier between the layers above and below, allowing little movement between them. at the bottom is the deepwater zone, which is cold, saline, dense and more or less stable, never interacting with the atmosphere (except in polar regions where the pycnocline is not always present).
Density log, английский
This radioactivity contact log responds to variations in the specific gravity of formations by emitting neurtrons and measuring the secondary gamma radiation from the detector to the instrument. this is particularly helpful when measuring porosity in shaley sands.

Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.

- 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).

- 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.
