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 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
Accomplishment, английский
Выполнение (работ), реализация (плана)

Mixed bag, английский
- In naval mine warfare, an assembly of mines of various types, with different firing systems, arming delays, sensitivities, and counter settings.
- Used in the context of general equities. group of stocks which consists of some which are up, down, and neutral.
Mission command, английский
This is a time-honored style or concept of decentralized military command and control in which mutual trust between superiors and subordinates allows the former to set goals while giving the latter free rein to implement them. this worked well for at least three centuries, especially in pre-radio navies when centralized commanders could tell a captain what to achieve and why it was necessary, but once on a remote station the captain had to use his own initiative to decide how best to reach the goal; even to the extent of disobedience—as nelson demonstrated more than once. in july 1799, then a captain, he wrote, “the orders i have given ... are, in a great measure, contrary to those he (the admiral) gave me; but the service requires strong and vigorous measures to bring the war to a conclusion.” in contrast, during the 1914–18 war, telegraphic communications allowed “chateau-generals” to ignore helmuth von moltke’s admonition “no operational plan will ever extend with any sort of certainty beyond the first encounter with a hostile force,” and pre-plan the tactical minutiae of local actions in trenches they seldom visited. the author fears the possibility that “information age” concepts such as command and control and network-centric operations will produce centralized naval staffs who will stifle local initiative with a similar “we-know-best” attitude. this may, however, be offset by the concept of power to the edge.
