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.
Film, английский
- Thin, plastic sheeting having nominal thickness usually not greater than 0.010 inch.
- Whether photographic or holographic, film consists of light sensitive chemicals (the emulsion) spread on a surface. a film`s resolution measures the ability to distinguish between details. because holographic films must be able to record very detailed information, they have a resolving power of 50 or more times that of photographic film. they require either exposure to a high-intensity pulsed laser or a long exposure to a continuous wave laser. holographic film is developed in a manner similar to photographic film, by bathing it in a series of chemical agents.
- A photographic emulsion coated on a flexible translucent or transparent plastic base.
- A flexible base supporting an emulsion - light-sensitive in the case of movies and stills and magnetic in the case of video. also, informally, motion pictures. erick sommers insists that since both are film according to physicists, video-taping can technically be referred to as "filming."
- A compilation of light sensitive silver salts, color couplers (in color film), and other materials suspended in an emulsion and coated on an acetate base. the storehouse of our visions, nightmares, and dreams.
- A layer of one or more coats of paint or varnish covering an object or surface.
- A very thin layer of a substance covering a surface
