- N дифференциал semantic ~ псхлнгв. семантический диффе- ренциал5 differentiated a дифференцированный; over-~ сверхдифференцированный 1 один из возможных способов синтаксической реализации семантиче- ских актантов предиката. 2 словарь языка писателя, философа или общественного деятеля; до 1990-х гг. в отеч. лит. бытовал термин «писательский словарь». 3 словарь с указанием норм произношения. 4 англ. термином reverse dictionary (rd) и русским обратный словарь называются разные вещи. в rd реализуется принцип «от значения к слову», поэтому rd скорее являются словарями ассоциаций, нежели обратными словарями, где слова расположены в обратном (инверси- онном) порядке. 5 метод качественно-количественного индексирования значения слова с помощью двухполюсных шкал, на каждой из которых имеется града- ция с парой антонимических прилагательных.
- Разница в оплате труда квалифицированных и неквалифицированных рабочих одной отрасли или рабочих разных отраслей промышленности
- System of gears capable of dividing the input torque of one shaft between two output shafts where rotation at different speeds is ukely to occur, as in cornering. used as the final drive of vehicles with two or more driven wheels. see also crown wheel
- 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.
- Difference in value between two comparable items
- Difference in value between two comparable items change in value of one item compared to another (for example, a “cost-of-living differential” is the difference between the price of goods bought in the home country compared to the price of similar goods in the host country)
Differential (chassis), английский
A set or train of gears that change the direction of the vehicle propeller shaft to that of the axle shafts; also adjusts the amount of rotation between the right and left wheels on a particular driven axle to prevent wheel skidding when turning a corner.

Differential backup, английский
A backup containing only changes made to the database since the preceding data backup on which the differential backup is based.

A test that shows the amounts of different types of white blood cell in a blood sample
Differential case, английский
The case or housing for a differential, often forming a structural part of a live beam axle. also differential carrier (us), see also banjo axle. see figure d.5.
Differential coating, английский
Differential coherent psk, английский
Когерентная относительная фмн
Differential coils, английский
- Two or more physically adjacent and mutually coupled coils connected in series opposition such that an imbalance between them, causing a signal, will be produced only when the electromagnetic conditions are different in the regions beneath the coils. in contrast, comparator coils are not adjacent or mutually coupled. compare comparator coils. 19.8 aerospace nondestructive testing
- Две или более физически соседние и взаимно связанные катушки, соединенные последовательно друг против друга так, что дисбаланс между ними, вызывающий сигнал, будет возникать только тогда, когда электромагнитные условия различны в областях под катушками. напротив, катушки компаратора не расположены рядом и не связаны друг с другом. сравните катушки компаратора. 19.8 авиационный неразрушающий контроль
Differential coils (et), английский
Two or more coils electrically connected in series opposition such that any electromagnetic condition which is not common to the areas of the specimen being tested or the test specimen and the standard will produce an unbalance in the system and thereby be detected.
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.
- Яркость. для видеосигналов систем ntsc и pal

- A device for reducing the amplitude of a signal.
- A circuit that provides reduction of the amplitude of an electrical signal without introducing appreciable phase or frequency distortion.
- A component that incorporates a specific amount of loss into an operational optical network. s also provide a safety margin in planned networks to allow for electronics degradation over time, or physical changes to the optical component portion of the network. s come in two styles, fixed and variable. variable optical attenuators are used for testing systems for dynamic range and quality of signal testing
