Pyroclastic surge
| Глоссарий геологических терминов |
A low density, dilute, turbulent pyroclastic flow, usually very hot, composed of a generally unsorted mixture of gases, ash, pumice and dense rock fragments that travels across the ground at high speed and less constrained by topography than a pyroclastic flow; several types of pyroclastic surges can be specified (e.g. base surge, ash-cloud-surge). compare - pyroclastic flow. sw, sn, gg

Pyroclastic, английский
- Pertaining to fragmented (clastic) rock material formed by a volcanic explosion or ejection from a volcanic vent.
- An igneous rock composed of angular rock fragments that originate from a volcanic explosion.
- (adj.) pertaining to clastic rock particles produced by explosive, aerial ejection from a volcanic vent. such materials may accumulate on land or under water. compare - epiclastic, volcaniclastic, clastic. g. smith & hp
- General term for any rock composed of material ejected explosively from
Pyroclastic deposit, английский
Pyroclastic flow, английский
- Lateral flowage of a turbulent mixture of hot gases (≈400°c) and unsorted pyroclastic material (volcanic fragments, crystals, ash, pumice, and glass shards) that can move at high speed (100 miles an hour or more). also known as a "glowing avalanche" or "nueé ardente."
- A fast density current of pyroclastic material, usually very hot, composed of a mixture of gasses and a variety of pyroclastic particles (ash, pumice, scoria, lava fragments, etc.); produced by the explosive disintegration of viscous lava in a volcanic crater or by the explosive emission of gas-charged ash from a fissure and which tends to follow topographic lows (e.g. valleys) as it moves; used in a more general sense than ash flow. compare -pyroclastic surge, ash flow, nuee ardente, lahar. sw, sn, gg
Pyroclastics, английский
Surge, английский
- A momentary rise of pressure in a circuit.
- A vessel`s transient motion in a fore and aft direction.
- A sudden voltage rise and/or fall in an electrical current.
- Горизонтально-продольные перемещения судна
- A large swelling wave. also, the tapered part of the whelps between the chocks of the capstan, upon which the messenger is readily surged.—to surge, is to slacken up suddenly a portion of a rope where it renders round a pin, windlass, or capstan; as, “surge the messenger.” a ship is said to surge on a reef when she rises and falls with the heave of the sea, so as to strike heavily.
- [1] the difference between actual wave height and that considered normal or predictable (see also storm surge). [2] a swelling wave or billow. [3] one of six possible responses of a vessel to movement of the sea (see linear displacement and ship motion). [4] the bight of a rope. [5] to slacken a line by allowing it to slip around (for example) a windlass or capstan drum. [6] usn term for the deployment of a strike group ahead of schedule. [7] a pulsating speed variation by an engine or gas turbine. [8] a sudden flow of electricity. [9] the swash of liquid in a container. [10] the 2007 deployment of additional u.s. troops to iraq.
- An excessive amount of power drawn by an appliance when it is first switched on. inverters usually have a surge rating, which is the maximum surge current or power they can produce for a short period.
- An unexpected flow of excessive current, usually caused by excessive voltage, that can damage appliances and other electrical equipment.
- Попуск воды /в борозды при дискретном орошении/
- /flow/ valve распределительный клапан системы дискретного орошения /служит для попеременной подачи воды в разные группы борозд/
- Engine speeds up and slows down with no change in accelerator position or brake application by the driver.
