Positive cutoff
| Глоссарий по архитектуре и конструкциям |
Acutoff, 2 which extends downward to an impervious lower boundary, completely blocking the path of subsurface seepage. positive-displacement descriptive of equipment in which wet-mix shotcrete is delivered by being pushed through the material hose in a solid mass by a piston or auger.

Cutoff, английский
- The number of feet a bit may be used in a particular type of rock (as specified by the drill foreman).
- The point in the stroke of the piston of a steam engine where the entrance of live steam is stopped by the closure of the inlet valve.
- To close, shut off, or terminate. 4. minimum percentage of mineral in an ore that can be mined profitably.

Cutoff concentration, английский
Критическая концентрация. концентрация наркотического вещества в пробе, используемая для того, чтобы определить, является ли данная проба отрицательной или положительной [24]. в некоторых случаях рекомендуется устанавливать критическую концентрацию равной пределу обнаружения. см. threshold (порог).

Cutoff entry, английский
Cutoff frequency, английский
- Предельная частота
- The designated frequency of a filter after which the sound is not allowed to pass. in a high-pass filter, a high cutoff frequency will be excessively trebly and bright, as no low frequencies will be present. in a low-pass filter, a low cutoff frequency may be too muted and dark, as no high frequencies or overtones will be present.
- Upper or lower spectral response of a filter or amplifier, at which the response is a specified amount less (usually 3 or 6 db) than the maximum response. d
- Верхний или нижний спектральный отклик фильтра или усилителя, при котором отклик на определенную величину меньше (обычно на 3 или 6 дб), чем максимальный отклик. д
- Upper or lower frequency corresponding to the spectral response of a filter or amplifier, at a specified amount less (usually 3 db power or 6 db voltage/amplitude) than the maximum response.1 d d* (detectivity star): detectivity expressed inversely so that higher d*s indicate better performance. sensitivity figure of merit of an infrared detector. d* is taken at specific test conditions of chopping frequency and information bandwidth and displayed as a function of spectral wavelength.3 d* is the detectivity scaled to the unit sensitive detection area, with detectivity corresponding to the inverse of the noise equivalent flow.
- In ultrasonic testing, upper or lower spectral response of a filter or amplifier, at which the ultrasonic response is a specified amount less (usually 3 or 6 db) than the maximum response.
Cutoff grade, английский
Cutoff hole, английский
Cutoff mode, английский
The highest order mode that will propagate in a given waveguide at a given frequency.
Cutoff point, английский
The lowest rate of return acceptable on investments.
Cutoff relay, английский
Cutoff shot, английский
Cutoff spatial frequency, английский
Cutoff sprinkler, английский
A fire sprinkler whose heads produce a curtain of water across a door when a fire alarm system is activated; prevents the spread of flames.
Impervious, английский
- In ceramics, that degree of vitrification evidenced visually by complete resistance to dye penetration; generally signifies zero absorption of water, except for floor and wall tile, which may absorb up to 0.5% water.
- Impassable. rock strata, such as tight clays, shales, etc., which cannot be penetrated by water, petroleum, or gas.
Completely, английский
Вполне; полностью; совершенно
Subsurface, французский
Displacement, английский
- Перемещение
- Водоизмещение
- The weight of water displaced by the immersed volume of a ship`s hull, exactly equivalent to the weight of the whole ship.
- The weight, in tons of 2,240 pounds, of the vessel and its contents. calculated by dividing the volume of water displaced in cubic feet by 35, the average density of sea water.
- Перемещение, сдвиг, весовое водоизмещение,
- The fact of being moved out of the usual position fracture of the radius together with displacement of the wrist
- Водоизмещение судна
- Водоизмещение; водоизмещающее плавание
- The centre of gravity of the displacement relates to the part of the ship under water, considered as homogeneous. the weight of water which a vessel displaces when floating is the same as the weight of the ship. (see centre of cavity.)
- Weight of a vessel expressed as either the number of long tons, or the cubic feet of water, displaced by the hull (1 ton = 35 cu.ft of seawater or 35.9 cu.ft of fresh).
- The volume of liquid delivered by a single stroke of a pump piston.
- Sometimes used as a synonym for offset deflec tion, deviation, dislocation, throw.
- The capacity of an air compressor, usually ex pressed in cubic feet of air per minute (c.f.m.).
- The weight of water dislocated by the hull of a vessel.
- The weight of a boat measured according to the weight of water it displaces. a boat displaces an amount of water equal to the weight of the boat, so the boat’s displacement and weight are identical.
- Изменение линейного или углового положения* перемещение, отклонение органа управления
- The product of stroke and of cylinder bore and number of cylinders of an engine, representing the theoretical volume of (incompressible) working fluid that can be drawn into an engine with each cycle. see also capacity and swept volume. 45
- Displacement is where you change your nearest relative. the process of changing the nearest relative is often known as ‘displacement proceedings’. your nearest relative can be displaced if you or the local authority have concerns about the way that they are behaving. see our pages on the nearest relative for more information.
Descriptive, английский

- Наглядный; описательный

Horizon cloth, английский
Acyclorama fabricated of canvas.
Unit system, английский
Acurtain wall, 1 composed entirely of prefabricated units attached to the building structure. unit-type vent an opening of relatively small area (one of a number which are distributed about a roof according to the occupancy requirements), usually having a lightweight metal frame and housing, with hinged dampers which may be operated manually or which open automatically in the event of fire.
