Least upper bound, английский
- Точная верхняя грань см. glb
- In a partially ordered set, suppose that a ? c and b ? c. if c ? d for any element that also is3 both a and b then c is the least upper bound for elements a and b. see also: greatest lower bound, lattice, partially ordered set.
Lubricant, английский
- Any substance interposed between two surfaces in relative motion for the purpose of reducing the friction and/or the wear between them.
- Смазка, смазочный материал
- A fluid which lubricates
- Смазка, смазочное масло
- An oil or emulsion finish applied to fibers to prevent damage during textile processing, or to knitting yarns to make them more pliable.
- An oil or emulsion finish applied to fibers to prevent damage during textile processing or to knitting yarns to make them more pliable.
- Substance interposed between two surfaces in relative motion for the purpose of reducing the friction and/or wear between them.
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).

Lubon, английский
Lower-brained, английский
An affliction of females who think only their genitalia and not their brains. example the boys excused her insensitive and rude comments because they knew how lower-brained she was.
