Cleavage, английский
- In an adhesively bonded joint, a separation in the joint caused by a wedge or other crack-‑opening-‑type action.
- The repeated division of cells in an embryo cleavage lines cleavage lines plural
- N расщепление class ~ расщепление класса
- The splitting of any body having a structure or line of cleavage: as fir cleaves longitudinally, slates horizontally, stones roughly, smoothly, conchoidal, or stratified, &c.
- A breakable weak point or fracture, usually caused by weak molecular structure. a cleavage is likely to split if struck in a certain direction, and in uncut diamonds, it is used as a natural site for splitting crystals prior to cutting and polishing.
- A break in a diamond which is parallel to the diamonds crystal planes. a cleavage may be caused by internal strain or a sharp blow.
- The natural areas of a diamond or gem where weak bonds hold the atoms together. when a stone is cut, the cutter will ‘split’ the stone along these planes/the cleavage lines.
- A fragment of a crystalline substance, such as a diamond produced by cleaving.
- As used by crystallographers, the tendency for crystalline substances, such as diamonds, to split along planes that are always parallel to at least one of the possible crystal faces peculiar to the crystal structure of a specific mineral or substance.
- As used by petrographers, the tendency for rocks to split along definite, parallel, closely spaced planes, which may be highly inclined to the bedding planes.
- Property or tendency of a rock to split easily along aligned, usually closely-spaced
- The mitotic divisions of the early embryo that occur in the absence of growth to divide the embryo into too many smaller nucleated cells.
- The splitting (fracture) of a crystal on a crystallographic plane of low index.
Cleavage banding, английский
Cleavage crack, английский
Cleavage fracture, английский
- Разрушение по плоскости спайности; разрушение сколом
- A fracture, usually of a polycrystalline metal, in which most of the grains have failed by cleavage, resulting in bright reflecting facets. it is one type of crystalline fracture. contrast with shear fracture.
Cleavage of lateral epitaxial films for transfer (cleft), английский
- A process for making inexpensive gallium arsenide (gaas) photovoltaic cells in which a thin film of gaas is grown atop a thick, single-crystal gaas (or other suitable material) substrate and then is cleaved from the substrate and incorporated into a cell, allowing the substrate to be reused to grow more thin-film gaas.
- A process for making
Cleavage plane, английский
- In a crystalline material, such as certain types of rocks, a plane along which splitting takes place most easily.
- The crystallographic plane, which can be likened to the grain in wood, along which a crys¬talline substance such as diamond may be split easily. see cleavage 2.
Cleavage test, английский
A test that measures the resistance of a timber to splitting longitudinally along the radial and tangential planes
Cleavage, 4., английский
Cleavages, английский
As used by the diamond-cutting and diamond-besetting industries, the more or less flat diamond fragments produced by splitting a crystalline diamond along the octahedral plane. such fragments are used primarily as a material from which special-shaped, diamond-pointed cutting tools are produced.
Fan, английский
- Ventilateur
- Part of a chipper that creates an air stream, moving the chips out of the chipper housing (23).
- Portable chipper terms
- Вентилятор; турбовентиляторный двигатель 233
- Fink truss a form of fink truss having subdiagonals that radiate outward from a central point.
- Fink truss fanlight
- Веер (в одну п. выполнить *ст.с н., в.п.* повторить от * до * 4 раза, ст.с н.)
- Вентилятор
- To brace the upper yardarms slightly aft to benefit from differences in wind speed at their height above the water.
- Производственная сеть
- Gently-sloping mass of detrital material deposited at locations of
- Крыло ветряной мельницы
- False alarm normalizer (radar)

Fan angle, английский
The measure of angular spread of a line-generating laser. the fan angle determines the line length produced at a certain distance. calpac line-generating lasers have a 90° fan angle. a 90° fan angle will produce a line length that is 2x the projection distance (e.g. a 10 foot long line when projected from 5 feet). femtoseconds :10-15 seconds. 1 fs = 0.000,000,000,000,001 seconds.
Fan antenna; harp antenna, английский
Fan apron, английский
A sheet-like mantle of relatively young alluvium and soils covering part of an older fan piedmont (and occasionally alluvial fan) surface, commonly thicker and further down slope (e.g., mid-fan or mid-fan piedmont) than a fan collar. it somewhere buries an older soil that can be traced to the edge of the fan apron where the older soil emerges as the land surface, or relict soil. no buried soils should occur within a fanapron mantle itself. compare - fan collar. ffp
