HIGH-TEMPERATURE REACTOR, name title of a nuclear reactor (routinely grafito-gas) for which the working temperature in an active zone reaches 700 °S. The high-temperature reactor allows to create a power plant with a direct cycle in which the reactor and the turbine are connected directly.

TALL HERBAGE, grassy vegetation an altitude of 2-4 m, developing at a heightened atmospheric humidity and soils. Predominary in mountains, forest boundaries (napr are higher., Caucasus, Altai, and also in mountains of the Far East). The main representatives of a tall herbage - a cowparsnip, an angelica, a chervil, etc.

HIGH-FREQUENCY WELDING, weldment, at which edge of welded component parts heat up high-frequency currents to their ramollissement or melting away and squeeze. The current in an item is induced by an inductive or contact way. Use, napr., for a pipe welding from a tape.

HIGH-FREQUENCY DISCHARGE, electric discharge in the gas, originating in an electric field of a high frequency. On a way of a rendering of power distinguish: electrode, electrodeless, one-electrode, MICROWAVE - CATEGORY in cavity resonators and radio waveguides.

RUBBERY STATE, condition of amorphous polymers, in which they are capable to huge (up to hundreds %) to reversible deformations. Speaks that, that chain molecules of polymers can variate the form. The sample polymeric material maintained in rubbery state, - gum.

ALTITUDE, in geometry - a cutting of the perpendicular lowered from top of geometric pattern (napr., a triangle, a pyramid, a cone) on its grounding (or prolongation of the grounding), and also length of this cutting. An altitude of a prism, the cylinder, a spherical layer, and also truncated in bridge to the grounding of a pyramid and a cone - distance between the top and bottom groundings.

PITCH OF A TONE, quality of a note, the form of perception the person of vibration frequency of a soniferous body. With growth of frequency the pitch of a tone increases.

RISE OF TIDE, rule of a pitch tidal level at present, read out from a chart datum.

ALTITUDE SICKNESS, painful condition at rise on the high altitudes, stipulated by the considerable drop of fractional pressure of oxygen in an inhaled air: feeling of weariness, a vertigo, a headache, a nausea, a pain in ears, a syncope, etc.

ALTITUDE POJASNOST (altitude zonality), objective changeover of natural environments in mountains in accordance with increase of a true altitude. It is accompanied by changes geomorphological, hydrological, soil-building processes, structure of vegetation and fauna. Many features altitude pojasnosti are determined by an exposition of downslopes, their arrangement in relation to prevailing air masses and remoteness from oceans. The figure of belts will routinely increase in high mountains and with an approaching to equator.

HIGH-ALTITUDELY - COMPENSATORY the COSTUME, personal equipment of the pilot for protection against a parasite effect of a pressure fall in an event of a puncture of a sealed compartment by building adjustable external pressure. Together with a pressure helmet it is used at flights at the altitude up to 30 kms.

The ALTIMETER (altimeter), the device directing a flying height of a flight vehicle. A pressure altimeter measure an altitude concerning a departure point, radio altimeters - an altitude above proletaemoj terrain.

VYSOTSK (up to 1948 Uuras), city (with 1940) in the Russian Federation, the Leningrad region, on about. Vysotsky, a port in Finnish a hall. A depot. 1 thousand inhabitants (1991). It is based in nach. 18 century. Peter I as strength Trongzund; in 1918-40 in structure of Finland.
