Basalt, английский
- Volcanic rock (or magma) that is generally dark in color, contains 45 to 54 percent silica, and is rich in iron and magnesium. an eruption of basaltic magma is generally quiet, and results in flows (both vesicular and non-vesicular) and breccias. undersea eruptions commonly result in the formation of "pillow lavas." basalt represents the initial differentiated material erupted by the earth at spreading centers, and is considered by geoman to be the "blood of the earth."
- A dark, fine-grained, igneous rock used extensively for paving stones, but rarely for building stone.
- A dark-colored, fine-grained igneous rock, composed mainly of plagioclase feldspar and pyroxene, that is formed by the solidification of magma near the earth’s surface.
- As used in a general sense by drillers, a dark-colored igneous or volcanic rock.

- Bouclier;écran de protection
- A design carved or chipped out on the slabs of breton tombs. it is a highly version of an antropomorphic figure
- Any barrier to the passage of interference causing electrostatic or electromagnetic fields, formed by a conductive layer surrounding a cable core. it is usually fabricated from a metallic braid, foil or wire serving.
- Sylvania high intelligence electronic defense
- A double rivet with an ornamental head joining both rivets, normally used to attach hinges or other components to a frame.
- A metallic layer that surrounds insulated conductors in a shielded cable; may be the metallic sheath of the cable or a metallic layer inside a nonmetallic sheath; especially effective in providing protection against electrostatic interference.
- Функциональный экран
- Щит; экран; защита || защищать; экранировать
- A conductive enclosure (usually metallic) around one or more signal conductors, used to keep out electrostatic fields that can cause hum, buzz, or other noise.
- A metal frame used to maintain the opening as the tunnel boring progresses. as forward progress is made, the liner is constructed behind the shield, and the shield is jacked or moved forward.
- A layer or mass of material used to reduce the passage of ionizing radiation.

Shield coverage, английский
The amount of cable core surface area which is covered by a shield. it is expressed as a percentage of the cable core's total surface area. it is also called braid coverage when applied to a braided shield.
Shield cut, английский
