Critical, английский
- Критический
- A критический acquisition, age, period
- Said of a nuclear reactor when it is producing enough neutrons to be self-sustaining.
Critical activity, английский
Критическая работа (работа критического пути сетевого графика)
Critical alert, английский
An alert that indicates that a protection group requires immediate attention. critical problems are caused by significant abnormal (unexpected) behavior that affects data protected by dps.
Critical angle, английский
- The angle at which light in a high-refractive-index material undergoes total internal reflection. in geometric optics, at a refractive boundary, the smallest angle of incidence at which total internal reflection occurs.
- An angle of pitch of stairs or a ramp which is considered uncomfortable and unsafe if exceeded; this angle is 50° for stairs and 20° for ramps.
- Incident angle of the ultrasound beam where the refracted beam is parallel to the surface and above which a specific mode of refracted energy no longer exists.
- Угол падения ультразвукового луча, при котором преломленный луч параллелен поверхности и выше которого определенный вид преломленной энергии больше не существует.
- (1) in ultrasonic testing, incident angle of the ultrasound beam where the refracted beam is parallel to the surface and above which a specific mode of refracted energy no longer exists. see also mode conversion.18 (2) in visual testing, incident angle above which total internal reflection occurs. critical angle is key to the operation of fiber optics.
- Incident angle of the ultrasound beam where the refracted beam is parallel to the surface and above which a specific mode of refracted energy no longer exists.7,21
Critical angle (ut), английский
The angle of the incident sound beam with respect to the normal to an interface, beyond which a given mode of refracted beam will not exist.
Critical application, английский
Важное приложение; ответственное приложение
Critical appraisal, английский
Critical area, английский
Критический участок (программы)
Critical area of extraction, английский
Critical article on various works, английский
Critical assembly, английский
Critical band, английский
Critical band (width), английский
Critical behavior, английский
Критический режим
Critical buckling load, английский
Critical buckling load:, английский
The smallest bifurcation or limit load determined assuming the idealised conditions of elastic material behaviour, perfect geometry, perfect load application, perfect support, material isotropy and absence of residual stresses (lba analysis).
Critical buckling resistance, английский
Critical buckling resistance:, английский
The smallest bifurcation or limit load determined assuming the idealised conditions of elastic material behaviour, perfect geometry, perfect load application, perfect support, material isotropy and absence of residual stresses (lba analysis).
Critical buckling stress, английский
Critical buckling stress:, английский
- The nominal membrane stress associated with the elastic critical buckling load.
- The membrane stress associated with the critical buckling resistance.
Critical catholics, английский
Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a
Unsupported, английский

Deflection limitation, английский
The maximum deflection permitted by code or by good practice.
Drainage envelope, английский
The materials which completely surround a pipe, providing support and/or protection. drainage fill 1. lightweight concrete which is placed on roofs or floors to promote drainage. 2. a base course of granular material placed between a sub-grade and floor slab to retard the capillary rise of moisture. drainage fitting, durham fitting a castiron, threaded fitting, used on drainage pipes; has a shoulder such as to present a smooth, continuous interior surface.
