Oiliness
| Oil glossary |
- That property of a lubricant that produces low friction under conditions of boundary lubrication. the lower the friction, the greater the oiliness.
- Property of a lubricant that yields low friction under conditions of boundary lubrication, because of its affinity for metal surfaces. polar compounds in the lubricant enhances this property, causing a physical adherence (absorbance) to the surfaces; the lower the friction, the greater the oiliness.

Conditions, английский
- The terms of surrender.
- Обстоятельства; условия; режим
- Грузовая устойчивость ~ of crane during lifting operations грузовая устойчивость крана ~ of geometrical shape геометрическая неизменяемость ~ of slope устойчивость откоса ~ of volume постоянство объёма
- Наблюдения за работой сооружений в условиях эксплуатации
- Работа конструкции в условиях эксплуатационных нагрузок
- A set of specified constraints and parameters that are part of the rights group bundled into a rights label. these are enforced at the time of consumption.
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).
Absorbance, английский
- Спектральная поглощательная способность. в химическом спектральном анализе — мера интенсивности излучения (или света), поглощаемой образцом, и, следовательно, мера содержания абсорбирующего вещества в образце. обозначается буквой а и описывается уравнением,: a = lglo/h, где /о — интенсивность потока излучения , (или света), падающего на образец; а д — интенсивность, потока излучения (или .света), пропущенного .образцом. связана с коэффициентом пропускания (см. transmittance) уравнением a~igio( 1/т). термины «оптическая плотность» и «экстинк-ция», которые часто применялись для обозначения поглоща-тельной способности, следует изъять из употребления. погло-дцательная способность .складывается из поглощательнрй способности образцами кюветы; поглощательная способность самого `образца называется «внутренней поглощательной способностью» или «внутренней плотностью пропускания». . ср. показатель поглощения (absorption factor).
- The ability of a substance to transform radiant energy into a different form, usually with a resulting rise in temperature. mathematically, absorbance is the negative logarithm to the base 10 of transmittance.
- When a molecule captures energy from a photon and vibrates or stretches, using the energy

Oiliness agent, английский
An additive, usually polar in nature, used to improve the lubricity of a mineral oil. now usually called a boundary lubrication additive.
Oil sampling, английский
A procedure which involves the collection of a volume of fluid from lubricated or hydraulic machinery for the purpose of performing oil analysis. samples are typically drawn into a clean bottle which is sealed and sent to a laboratory for analytical work.
