- Density
- Diffuse elastic neutron scattering spectrometry
- A tooth, or something shaped like a tooth

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
- Плотность; концентрация; удельный вес
- 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).
- As usually applied to wood of normal cellular form, density is the mass per unit volume of wood substance enclosed within the boundary surfaces of a wood-‑plus-‑voids complex
- (1) the weight of a material per unit volume; (2) a measurement of the transparency of a medium, as related to light transmission.
- The degree of aggregation; the quantity of any entity distributed over an area per unit of areal measure, e.g., persons per acre, families per acre, or dwelling units per square mile.
- 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
- In relation to population, the number of individuals in a certain amount of space. absolute d.: number of organisms over unit of volume [1/m3]. relative d.: comparison of relative density, e.g. here more, there less.
- Mass per unit volume usually expressed as grams per cubic centimeter (g/cc). also known as specific gravity.
- The degree of darkness of an image. deny (pn)
- The mass per unit volume (usually expressed as grams per cubic centimeter). (also see specific gravity.) dent: on a loom, the space between the wires of a reed. deregistering (crimp): process of disordering or disaligning the crimp in a tow band to produce bulk. (also see threaded-roll process.)
- 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.
Плотность, русский
- (?) , масса единичного объема вещества. величина, обратная удельному объему. отношение плотности двух веществ называют относительной плотностью (обычно плотность веществ определяют относительно плотности дистиллированной воды).
- Масса единицы объема материала в плотном (без пустот и пор) состоянии.
- Вес смазочного средства в граммах на см3 (мл) при 20°c.

Scattering, английский
- Утруска
- Intrinsic fiber losses caused by undissolved particles, boundary roughness, and intrinsic material losses
- Loss of light that is scattered off atoms in different directions, so it escapes from the fiber core. a major component of fiber attenuation.
- Рассеяние. процесс, в ходе которого происходит изменение направления или энергии падающей частицы или радиации, вызываемое столкновением с другой частицей или системой частиц (мос, 5). рассеяние ми — рассеяние электромагнитного излучения сферическими частицами при отсутствии четкой зависимости между размером частиц и длиной волны излучения. оно имеет большое значение для исследований по загрязнению атмосферного воздуха. свет интенсивно рассеивается частицами диаметром около 0,1—1 мкм; происходящее при этом снижение видимости является функцией квадрата радиуса частиц. рассеяние рэлея — рассеяние частицами, радиус которых меньше ую длины волны излучения (например, рассеяние света молекулами кислорода и азота в воздухе).
- Reflection of ultrasonic waves by small discontinuities or surface irregularities.
- Uncontrolled reflection of ultrasonic waves by small discontinuities or surface irregularities.7
