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).
Density, французский
Measured in grams per cubic centimeter (or kilograms per liter); the density of water is 1.0; iron is 7.9; lead is 11.3.

Density function, английский
Функция плотности
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.
Definition, английский
- The fidelity of a television system to the original scene.
- Also called resolution. the fidelity with which detail is reproduced by a television system ranging from a fuzzy to a sharp appearance.
- The fidelity of reproduction of the pattern edge relative to the original master
- N дефиниция, определе- ние
- A verbal representation of a concept which serves to differentiate it from related concepts and allows humans to recognize and agree on the concept.
- Description of linear demarcation sensitivity or the detail sharpness of object outline in a radiologic test image. it is a function of screen type, exposure geometry, radiation energy, and characteristics sensor (such as film).
- Описание чувствительности к линейной демаркации или четкости контуров объекта на радиологическом контрольном изображении. это зависит от типа экрана, геометрии экспозиции, энергии излучения и характеристик датчика (например, пленки).
Transparency, английский
- Прозрачность; остекление (кабины)
- Прозрачность
- Транспарентность обязательство публиковать законы, правила, судебные решения и административные распоряжения общего применения, а также международные соглашения, имеющие отношение к торговле товарами и услугами
- A security model that helps developers write and deploy secure libraries and applications by isolating code depending on privilege. level 1 transparency was introduced in the .net framework version 2.0. it enables developers to annotate code to declare which types and members can perform security elevations and other trusted actions (security-critical) and which cannot (security-transparent). level 2 transparency, which was introduced in the .net framework 4, refines this model. it adds a third group of code, security-safe-critical code, which are types or members that access secure resources and can be safely used by partially-trusted code in the .net framework.
- A standard that requires that the structure for processing personal information be in a fashion that is open and understandable to the individual whose data is being processed. it is a goal of the fair information practices, which requires a company to inform users what personal information the company collects and how the data is used.
- The quality that defines how much light passes through an object’s pixels.
- Свойство системы ии, позволяющее осуществлять внешний контроль данных, функций, алгоритмов и методов обучения переживаний и чувств.
- The gdpr data protection regulation specifies that the organisation must publish information related to the processing of personal data that is accessible and easy-to-understand. see also data accountability.
- Openness of the regulatory process: features of regulatory transparency include clarity of regulatory roles, responsibilities and objectives, predictability of decisions, accountability, stakeholder participation and open access to (non-strategic) information through documents placed in the public domain. such openness increases the legitimacy of regulatory agencies and the public acceptance of decisions.
- Прозрачность (об отчетности, процедурах, практике)
- The property of allowing light to pass through
- Openness about activities and related decisions that affect academia and society and willingness to communicate these in a clear, accurate, timely, honest and complete manner.
