Lumen
|
- Unit of light measurement of light radiation. 1 lumen = amount of light emitted by a light source of 1 candela.
- In wood anatomy, the cell cavity.
- Люмен
- Unit of light flux.
- Unit of luminous flux defined as total flux in a space angle of one steradian and
- A unit of measurement of incident light. lumens, like lux, flux, candela, foot candles, foot lamberts, and watt/seconds, were created by scientists and engineers to confuse artists.
- 1. an si unit of light emitted per second 2. the inside width of a passage in the body or of an instrument such as an endoscope 3. a hole at the end of an instrument such as an endoscope
- Space inside the cisternae of the endoplasmic reticulum in eukaryotic cells

Lumen, латинский
(лат.) — свет. lumen naturale и lumen supranaturale — см. метафизика света.
Cвет., русский
Люмен, русский
- Единица измерения светового потока. один люмен равен световому потоку, излучаемому в телесном (пространственном угле) однородным точечным источником с силой света в одну канделу. при измерении светового потока в люменах используют метод, в котором маленьк
- (от лат . lumen - свет), единица светового потока си; обозначается лм. 1 лм - световой поток, испускаемый точечным источником в телесном угле 1 ср при силе света 1 кандела.
- Люмен (лат. lumen - свет), единица светового потока в международной системе единиц (си).
- Единица измерения светового потока в международной системе единиц. сокращённое обозначение: русское лм, международное lm. cd * sr
- Это мера общего количества видимого света, испускаемого источником в единицу времени.
Просвет, русский
- Просвет , отверстие
- Расстояние, в нерабочем положении, между подвижным и фиксированными столами или плитами гидравлического пресса. в случае многоярусного пресса, просвет — расстояние между смежными плитами. просвет обеспечивает пространство для удаления отливки/заготовки из пресс-формы/матрицы.

Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].
Instrument, английский
- A term used to describe a sensor (or sensors), the associated transducer(s), and the data read-out or recording device.
- (измерительный) прибор
- One of many terms for a light, heard mostly in the theater. see: lights.
- A piece of equipment or a tool the doctor had a box of surgical instruments.
- A term of extensive application among tools and weapons; but it is here introduced as an official conveyance of some right, or the record of some fact.
- A legal document that records an act or agreement and provides the evidence of that act or agreement. instruments include contracts, notes, and leases (e.g. a debt instrument).
- Навести инструмент ~ of application точка приложения (напр, силы) ~ of certainty тройная засечка ~ of compound curvature точка сопряжения двух кривых ~ of concentration замыкающий створ ~ of contraflexure точка перегиба ~ of curvature начало или конец кривой (в плане) ~ of cusp точка сопряжения обратных кривых ~ of grade intersection точка перелома в продольном профиле ~ of high stress concentration точка концентрации высоких [значительных] напряжений ~ of inflection точка перегиба ~ of intersection вершина угла (на плане трассы) ~ of lateral restraint точка бокового закрепления [защемления] (сжатого или изгибаемого элемента) ~ of support точка опоры ~ of switch конец остряка ~ of tangency начало или конец кривой (в плане) ~ of the maximum bending moment точка максимального изгибающего момента ~ of vertical curve начало вертикальной кривой ~ of vertical intersection вершина угла вертикальной кривой ~ of vertical tangent начало или конец вертикальной кривой ~ of zero moment точка нулевого момента (на эпюре моментов)
- Прибор, инструмент
- To tag the source code in order to measure the amount of time spent in each area.

Luminance, английский
- Brightness. in cctv refers to the part of the video signal that contains information about the scene brightness.
- Яркость. составляющая изображения, определяющая его относительную яркость в каждой точке экрана монитора
- This refers to the part of a video signal that carries the monochrome information. i.e. brightness information.
- Luminous intensity (photometric brightness) of any surface in a given direction per unit of projected area of the surface as viewed from that direction, measured in foot lamberts (fl).
- Luminous intensity (photometric brightness) of any surface in a given direction per unit of projected area of the surface as viewed from that direction, measured in footlamberts (fl).
- Refers to the video signal information about the scene brightness. the measurable,
- The part of a composite video signal that expresses brightness. also called y. separately transmitted in y/c (s-video).
- 1. luminous flux emitted, rejected, or transmitted per unit of solid angle per projected area of the source. 2. the photometric equivalent of brightness. 3. the brightness part of a television picture.
- Refers to the video signal information about the scene brightness. the measurable, luminous intensity of a video signal. differentiated from brightness in that the latter is nonmeasurable and sensory. the color video picture information contains two components, luminance (brightness and contrast) and chrominance (hue and saturation). the photometric quantity of light radiation.
- The luminous intensity of any surface in a given direction per unit of projected area of the surface, as viewed from that direction; a directional property of luminous radiation.
- The perceived brightness component of a given color, as opposed to its hue or its saturation.

- Ratio of a surface’s luminous intensity in a given direction to a unit of projected area. measured in candela per square meter.
- Photometric brightness of a light source defined by the density of its luminous intensity, measured as luminous flux per unit solid angle per unit area in a given direction. reported in candela per square meter (cd·m–2).
- Photometric brightness of a light source defined by the density of its luminous intensity, measured as luminous flux per unit solid angle per unit area in a given direction. reported in candela per square meter (cd/m2). compare illuminance. 504 glossary l-m luminous efficacy; luminous efficiency: ratio of the total luminous flux of a light source to the total radiant flux or to the power input.
- Photometric brightness of a light source as defined by the density of its luminous intensity. luminance is a measure of the luminous flux per unit solid angle per unit area in a given direction and is reported in candela per square meter (cd·m–2).
