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 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 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.
- Plane or planes along which a stone may likely break or delaminate.
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.
Membrane, английский
- In built-up roofing, a weatherresistant (flexible or semiflexible) covering consisting of alternate layers of felt and bitumen; fabricated in a continuous covering and surfaced with aggregate or asphaltic material.
- A thin layer of tissue which lines or covers an organ
- Same as arachnoid
- Диафрагма
Membrane, французский
Membrane antigen, английский
Поверхностный антиген; мембранный антиген антиген наружной клеточной мембраны.
Membrane attack complex (mac), английский
Ring structure formed from complement proteins c6 through c9 that penetrates the membranes of a targeted cell, causing cell lysis and death
Membrane battery, английский
Membrane concentration potential, английский
Membrane conductance, английский
Membrane curing, английский
A process in which either a liquid sealing compound (e.g., bituminous and paraffinic emulsions, coal-tar cutbacks) or a nonliquid protective coating (e.g., sheet plastics) functions as a film to restrict evaporation of mixing water from a fresh concrete surface.
Membrane field strength, английский
Membrane filter, английский
Separation, английский
- Разделение, отделение; эшелонирование; интервал эшелонирования
- Отделение, разделение; эшелонирование; интервал эшелонирования
- The development of layers of paint of different composition in a can during storage when the materials are not completely soluble, miscible, or stable.
- The act of separating or dividing two or more people or things, or the state of being separated
- Супругов, судебное разлучение

Poulticing, английский
Method of drawing soluble salts or stains out of stone by applying an absorbent such as clay or diatomaceous earth, mixed to a paste with water or cleaning solvent.
Six-cut finish, английский
Medium bush-hammered finish, similar to but coarser than 8-cut, with markings not more than 1/8" apart.
