Concentration, английский
- The amount of a substance present in a certain amount of soil, water, air, food, blood, hair, urine, breath, or any other media.
- Concentración
- N концентрация
- Концентрация; кучность
- The area covered by the diamonds as compared with the total area of the cutting surface of a surface-set bit.
- The volume of diamonds, expressed in percent, compared to the total volume of the crown of an im pregnated bit
- The percentage of acid compared with the volume of water added to produce a dilute solution.
- Концентрация. количество вещества, выраженное в единицах массы или молярных единицах, в единице объема жидкости или единице массы твердого тела. con. dence interval
- Концентрация. количество вещества, выраженное в единицах массы или молярных единицах, в единице объема жидкости или единице массы твердого тела.
Electron, английский
- The electron is a low mass particle ( 1/1836 that of a proton ) with a unit negative electric charge. in simple terms the electrons are said to orbit around the nucleus of atoms . positively charged electrons can also exist, these being known as positrons
- Negatively charged particle of an atom.
- An elementary particle of an atom with a negative electrical charge and a mass of 1/1837 of a proton; electrons surround the positively charged nucleus of an atom and determine the chemical properties of an atom. the movement of electrons in an electrical conductor constitutes an electric current.
- An elementary particle of an atom with a negative electrical charge and a mass of
- One of the fundamental constituents of atoms. the electron is a very small negatively charged particle with a rest mass of approximately 1/1836 that of the hydrogen atom, or 9.107 x 10-28 gm. it has an electric charge of 4.802 x 10-10 statcoulomb (the electrostatic unit of charge). electrons appear to be uniform in mass and charge.
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).
Cathode, английский
- Катод
- The negative electrode of a gas laser used for electrical excitation of the gas in the tube.
- The negative electrode in an electrolytic cell.
- The negative pole or electrode of an electrolytic cell, vacuum tube, etc., where electrons enter (current leaves) the system; the opposite of an anode.
- The negative electrode in a battery, diode or other electrical device.
- The negative pole or electrode of an electrolytic cell, vacuum tube, etc., where
- (1) negatively charged terminal in an arrangement that produces current by chemical reactions. compare anode. (2) in radiologic testing, the negative electrode of an x-ray tube, the electrode from which electrons are emitted.
- (1) отрицательно заряженная клемма в устройстве, которое производит ток в результате химических реакций. сравните анод. (2) при радиологических исследованиях - отрицательный электрод рентгеновской трубки, электрод, из которого испускаются электроны.
- Negatively charged terminal in an arrangement that produces current by chemical reactions. compare anode. celsius (centigrade): temperature scale based on 273 k (0 °c = +32 °f) as the freezing point of water and 373 k (100 °c = 212 °f) as the boiling point of water at standard atmospheric pressure. a relative scale related to the kelvin scale (0 °c = 273.12 k; 1 °c = 1 k).
- (1) negatively charged terminal in an arrangement that produces current by chemical reactions. compare anode. (2) in radiography, the negative electrode of an x-ray tube, the electrode from which electrons are emitted.
