- A system of gears that allows the outside driven wheel to rotate faster than the inside driven wheel when turning a corner. conventional “open” differentials direct engine power to the wheel with the least traction, which can be a problem on slippery surfaces. to combat this, some vehicles are equipped with “limited-slip” differentials that ensure some power is always delivered to both driven wheels.

- Насыщенность
- Насыщенность (цвета). показатель, описывающий силу цвета и его уровень серого. мера чистоты цвета, определяющая количество содержащегося в нем серого. чем выше содержание серого, тем ниже насыщенность цвета
- In color, the degree to which a color is diluted with white light or is pure. the vividness of a color, described by such terms as bright, deep, pastel, pale, etc. saturation is directly related to the amplitude of the chrominance signal.
- Насыщение
- The degree to which a color is undiluted by white light. if a color is 100 percent saturated, it contains no white light. if a color has no saturation, it is a shade of gray.
- The degree of intensity of a hue. also, the result of hanging a hot light under an automatic sprinkler head.
- Saturation is the depth of the colors within a photographic image. photographs with deep levels of color are described as being heavily saturated. a photograph with lighter levels of saturation is described as having a muted color palette. a totally desaturated color photograph becomes monotone—or black and white.
- 1) in a communications system, the condition in which a component of the system has reached its maximum traffic handling capacity. 2) the point at which the output of a linear device, such as a linear amplifier, deviates significantly from being a linear function of the input when the input signal is increased. 3) the degree of the chroma or purity of a color.
- In color, a vividness, or intensity. some films have more inherent color saturation than others. saturation can be slightly increased by moderate film pushes, or by slight underexposure of certain slide films. saturation can be increased in color negative film by moderate overexposure.
- The degree to which a colour is undiluted by white light. if a colour is 100 percent saturated, it contains no white light. if a colour has no saturation, it is a shade of grey.
- A most important aspect in producing high quality leathers. full saturation of tanning, fat liquors and dyes are essential in the production of fine leathers. self-covered seat deck: in upholstered furniture, using cover fabric to cover area under loose cushions. also called self-covered deck. selvage: tightly woven edges that prevent fabric from fraying on the roll. the selvage must be cut away for many fabrics to drape smoothly. serpentine form: profile made up of convex curve flanked by two concave curves.
- N насыщение; запол- нение актантных позиций saussurean a соссюрианский
- Насыщение-отбора проб. обычно, особенно в сша, так называется прибор, в котором имеются таймер (регулятор выдержки времени), коллектор и 6 или более клапанов с проходным отверстием для подачи воздуха в различные устройства для забора проб через заданные интервалы времени. этот термин относится также к автоматическому устройству для ежечасных: замеров концентрации дыма. воздух пропускается при постоянной скорости через бумажный фильтр, на котором после этого остается темное пятно дымовых частиц. фильтровальная бумага (в виде свернутой в трубочку полоски шириной: 20—30 мм) проходит через зажим фильтра, закрепленный пружинами для обеспечения герметичности. в конце каждого-часа зажим открывается и полоска бумаги продвигается вперед на 40—50 мм, после чего зажим опять защелкивается. в результате на бумаге образуется ряд пятен, каждый час-по одному пятну. термин «последовательный пробоотборник» иногда применяется также для обозначения полуавтоматического прибора (см. semi-automatic apparatus).

- In color management, the purity of a color’s hue, moving from gray to the pure color. save (v)
- 1. the maximum intensity or purity of a color. if the color is as brilliant as possible, it is at saturation; if the color is subdued or grayed, it is dull, weak, and low in intensity. 2. the upper limit concentration of a solute in a solvent, i.e., no more solute can be dissolved at a fixed temperature and pressure.
- The intensity or purity of a hue; the color of the greatest purity are those in the spectrum. words used to describe saturation are vivid, dull, brilliant, dark, deep, light, medium, pale, and weak.
- Condition in which high amplitude signals on a display screen do not increase with increased gain and appear flattened.
- Relative or comparative color characteristic resulting from a hue’s dilution with white light.

Brightness, английский
- Term for the intensity of illumination of a reproduced video picture.
- The attribute of visual perception in accordance with which an area appears to emit or reflect more or less light (this attribute of color is used in the color model hsb - hue, saturation, brightness). see lightness.
- A term to indicate the relative amount of light intensity available. brighter is more light, dimmer is less light. in an infrared system, the brightness control may affect actual image intensity or it may change the temperature range displayed. either eff
- The attribute of visual perception in accordance with which an area appear to emit more of less light. (luminance is the recommended name for the photo-electric quantity which has also been called brightness.)
- In ntsc and pal video signals, the brightness information at any particular instant in
- Яркость
- The value of a pixel in an electronic image, representing its lightness value from black to white. usually defined as brightness levels ranging in value from 0 (black) to 255 (white).
- In ntsc and pal video signals, the brightness information at any particular instant in a picture is conveyed by the corresponding instantaneous dc level of active video. control is an adjustment of setup (black level, black reference).
- Is strictly defined as an attribute of a visual sensation according to which an area appears to emit more or less light. we sometimes misuse the term brightness in this catalog instead of the more correct “luminance.” luminance, used for sources, is the luminous flux in an elemental beam from a given point per unit area per solid angle in the specified direction.
- The visual sensation of the luminous intensity of a light source. the brightness of a laser beam is most closely associated with the radiometric concept of radiance.
- A term mostly used in a qualitative way, related to the output power and beam quality of a laser; quantitatively
- The luminance of objects. the brightness of any area of the subject is dependent on how much light falls on it and how reflective it is. brightness range is the relationship we perceive between the light and dark subjects in a scene. brightness contrast is a judgment of the relative measure of that range, such as high, low, or normal. brightness values are sometimes referred to as ev (exposure values), a combination of aperture and shutter speed. brightness values in the scene are translated to tonal values on film.
- Value of a pixel in a digital image giving its value of lightness from black to white, with o being black and 255 being white.
- That attribute of visual perception in accordance with which a surface appears to emit more light or less light. now called luminance.
- The amount of light that is emitted by a computer monitor or picture displayed on the monitor.
