Rings
| Oil glossary |
- Circular metallic elements that ride in the grooves of a piston and provide compression sealing during combustion. also used to spread oil for lubrication.
- The annual circular layers in timber. also, grommets, or circles of metal for lifting things by hand, or securing the points of bolts, &c., as hatch or port rings.
- Trading arenas located on the floor of an exchange in which traders execute orders. sometimes called a pit.

Compression, английский
- A state or condition of being pushed or shortened by a force.
- Сжатие
- Сжатие (данных), уменьшение размеров файла изображения. см. также lossy и non-lossy. процесс упаковки данных с целью уменьшения занимаемого ими пространства на накопителе
- Компрессия, сжатие
- The reduction of volume of a vapor or gas by mechanical means.
- Digital video pictures can be compressed with a number of techniques. these include: jpeg and jpeg-2000 (for still images), m-jpeg and mpeg (for moving pictures).
- The reduction in gain at one level of a picture signal with respect to the gain at another level of the same signal.
- A digital photograph creates an image file that is huge, a low-resolution 640x480 image has 307,200 pixels. if each pixel uses 24 bits (3 bytes) for true color, a single image takes up about a megabyte of storage space. to make image files smaller almost every digital camera uses some form of compression. see the jpg entry below.
- The application of any of several techniques that reduce the amount of information required to represent that information in data transmission. this method reduces the required bandwidth and/or memory.
- A method of reducing the size of a digital image file to free up the storage capacity of memory cards and hard drives. compression technologies are distinguished from one another by whether or not they remove detail and color from the image. lossless technologies compress image data without removing detail, while "lossy" technologies compress images by removing some detail. joint photographic experts group (jpeg) is a lossy compression format supported by jpeg, pdf and postscript language file formats. most video formats are also lossy formats. tiff files are not and, as such, are far more stable than jpegs and other lossy file formats.
- Reducing the number of bits needed to encode a digital signal, typically by eliminating long strings of identical bits or bits that do not change in successive sampling intervals (e.g., video frames).
- A digital photograph creates an image file that is enormous. to enable image files to become smaller and more manageable cameras employ some form of compression such as jpeg. raw and tiff files have no compression and take up more space.
- 1. the act of squeezing or pressing the first-aider applied compression to the chest of the casualty. 2. a serious condition in which the brain is compressed by blood or cerebrospinal fluid accumulating in it or by a fractured skull
- Смыкание (губок захватного устройства) cm. соmрutеr-соntrоllеd rоbоt 33. соntinuоus-раth mоtiоn движение робота по полностью программируемой траектории (при котором полная траектория, описываемая рукой манипулятора, программируется на программоноситель во время обучения так, чтобы каждая точка вдоль траектории движения регистрировалась для дальнейшего воспроизведения)
- Сжатие (данных); уплотнение; свертка; компрессия; упаковка

- Сжатое волокно; ~ in
- The intentional reduction in dynamic range to increase sustain and/or add punchiness, caused by a the use of a compressor/limiter.
- A process for removing redundant data from a digital media file or stream to reduce its size or the bandwidth used.
- A reduction of the time available for a scheduled storyboard to reach its final state.
- A way of making files smaller, either to fit into restricted storage space or to speed up transmission over the internet. popular compression standards include- jpeg- and- gif- for pictures,- mp3for music files,- mpeg, mp4, avi- and- mov- for movie footage, and- zip- for just about everything else.
Combustion, английский
- Сгорание; горение
- Горение, сожжение
- Any chemical process that produces light and heat as either glow or flames.
- Burning, &c. (see spontaneous combustion.)
- Сгорание, сжигание, горение, возгорание
- Сгорание. химическая реакция, при: которой вещество соединяется с кислородом с выделением тепла: «горение». сгорание топлива, содержащего углерод и водород, считается полным, если цроисходит полное окисление этих двух элементов до углекислого газа и воды. неполное сгорание может привести к тому, что: 1) в золе остается значительное количество углерода; 2) часть углерода выделяется в виде окиси углерода; и 3) молекулы топлива реагируют с образованием ряда продуктов более сложного состава по сравнению с исходными молекулами топлива, и если эти продукты не сгорают, они выделяются в виде дыма. сгорание летучих продуктов может протекать более полно, если сверху на слой топлива подается так называемый вторичный воздух (воздух, пропускаемый через слой топлива, называется «первичным»). воздух сверх количества, теоретически необходимого для полного сгорания (избыточный воздух), следует подавать с минимальным избытком, чтобы` избежать неоправданных потерь тепла с дымовыми газами, слабой теплопередачи и окисления двуокиси серы в трехокись. перенасыщенное сгорание происходит в системе, где топливо подается сверху на раскаленный слой топлива. такая система характеризуется тенденцией к образованию дыма. тороидальное (кольцевое) сгорание происходит в системе, где в печи поддерживается вихревой поток; это увеличивает время пребывания топлива в печи и настолько улучшает горение, что дополнительной подачи воздуха, требуется мало или не требуется совсем. 40
- A combustion reaction involves a substance combining with an oxidizer, releasing a large amount of heat (exothermic) and produces a flame. the heat produced can make combustion self-sustaining. an oxidizer is a compound that takes electrons in a reaction and can promote or initiate combustion. oxygen and chlorine are examples of oxidizers. when oxygen is available in sufficient amounts, complete combustion occurs. if a hydrocarbon undergoes complete combustion, carbon dioxide and water vapor are produced. combustion reactions can be oxygen starved or can involve excess oxygen. in an oxygen starved combustion reaction, a combustion reaction has a limited oxygen supply and incomplete combustion occurs. in an environment of combustion in excess air, the amount of oxygen supplied to the combustion reaction is more than is needed for complete combustion and can lead to a hotter, faster burning fire.
- A chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.
- The chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.
Lubrication, английский
- The control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. the lubricant used can be a fluid, solid, or plastic substance.
- Смазка
- On no account should oil be used to lubricate pin-tumbler cylinders. graphite is the conventional lubricant for this mechanism.
- Смазка (действие)
- The act of injecting a fluid, normally bentonite and/or polymers, to reduce the skin friction and jacking forces on the jacking pipe during installation. the fluid fills the annular space.
- Means of reducing friction either around a pipe being jacked or a shaft being sunk into the ground.
- The control of friction and wear between two moving, touching surfaces by placing a friction-reducing substance between them.
- Control of friction and wear by the introduction of a friction reducing film between moving surfaces in contact. the film may be fluid, solid or plastic.
- Reduction of friction or wear between two load-bearing surfaces by the application of a lubricant; includes boundary lubrication (thin or interrupted fluid film, especially bearings where wear occurs); mixed film, where some liquid pools support the load; elastohydrodynamic (high-pressure loads increase the lubricant’s viscosity and load-carrying capacity, especially in gears); hydrodynamic (a thick fluid film lubrication, especially in journal bearings) and hydrostatic (external pump pressure used to form a thick fluid film, as in start-up of journal bearings).

Roller bearing, английский
- An antifriction bearing comprising rolling elements in the form of rollers.
- Describes all rolling bearings except for ball bearings (see rolling element et al).
Ring sticking, английский
- Freezing of a piston ring in its groove in a piston engine or reciprocating compressor due to heavy deposits in the piston ring zone.
- Sticking of the piston ring in its groove, usually due to heavy deposits in the piston ring zone.
