Cleavage plane
| Глоссарий по архитектуре и конструкциям |
- 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.
- Plane or planes along which a stone may likely break or delaminate.

Плоскость скола, русский
Характеристика кристаллографической плоскости или ряда плоскостей в кристалле, в которых происходит скол.

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.
- The ability of a rock mass to break along natural surfaces; a surface of natural parting. also used to refer to the plane or planes along which a stone may likely break or delaminate.
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 membrane, английский
Membrane that provides a separation and slip sheet between the mortar setting bed and the backing or base surface.
Cleavage membranes, английский
Designed to separate the backing surface from the mortar setting bed
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 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.
Plane, английский
- Плоскость; самолет
- To skim over the water at high speed rather than push through it.
- A flat surface, especially that of the body seen from a specific angle
- In a general sense, a perfectly level surface; but it is a term used by shipwrights, implying the area or imaginary surface contained within any particular outlines, as the plane of elevation, or sheer-draught, &c.
- [1] to gain enough speed to lift the forward part of a vessel’s hull so that it rides on the surface of the water with minimum resistance. [2] abbreviation of hydroplane or diving plane. [3] abbreviation of aeroplane or airplane.
- Точка на плоскости; to ~ the
Plane, латинский
Plane -, английский
Плоская деформация
Plane ashlar, английский
A stone block having tool marks on its surfaces.
Plane bed, английский
Plane captain, английский
Usn flight deck enlisted person responsible for the material condition, start-up, movement, launch, and recovery of a specific naval aircraft. these brown shirted airmen are usually the youngest and least experienced in a squadron, too fresh to have yet chosen a rate or occupational specialty, but they carry huge responsibilities, serving as liaison between pilot and ground crew and even having their names and home towns stenciled on their aircraft. they conduct safety checks and inspections, take the pilots through start-up procedures and no aircraft may take off or even taxi without clearance from its plane captain.
Plane charge, английский
Кумулятивный заряд с большим более
Plane course, английский
Plane deformation, английский
Plane detonator, английский
Плоскодонный детонатор
Crystalline, английский
- A substance or rock composed largely or wholly of mineral crystals.
- Transparent, clear, or pure.
- Made up of crystals. the term crystalline applies to sections of all chemical fibers, which consists of alternate crystalline and amorphous (noncrystalline) regions. these regions are influenced by manufacturing conditions and to some extent can be controlled. the degree of crystallinity influences the physical properties of fibers.
Crystallographic, английский
Delaminate, английский
|
Purlin plate, английский
In a curb roof, a purlin which is located at the curb and which supports the ends of the upper rafters.
Bonus clause, английский
In a construction contract, a provision that permits a bonus payment, by the owner to the contractor, for early completion of construction work or for a saving in construction costs. also called a bonus provision. book matching, herringbone matching the assembling of wood veneers from the same flitch so that successive sheets are alternated face up and face down. in figured wood, side-byside sheets show a symmetrical mirror image about the joints between adjoining sheets.
