Что (кто) такое cutoff attenuation - определение

DISCONNECTED MEANDER LOOP OF A RIVER
Rincon (abandoned meander); Abandoned meander; Cutoff meander; Cutoff meander spur
A meander cutoff is a natural form of a cutting or cut in a river occurs when a pronounced meander (hook) in a river is breached by a flow that connects the two closest parts of the hook to form a new channel, a full loop. The steeper drop in gradient (slope) causes the river flow gradually to abandon the meander which will silt up with sediment from deposition.
Attenuation coefficient         
MEASURE FOR THE EXPONENTIAL REDUCTION OF A QUANTITY ALONG A PATH DUE TO ABSORPTION AND SCATTERING
Absorption coefficient; Absorption Coefficient; Linear attenuation coefficient; Linear coefficient; Linear absorption coefficient; Narrow beam attenuation coefficient; Scattering coefficient
The linear attenuation coefficient, attenuation coefficient, or narrow-beam attenuation coefficient characterizes how easily a volume of material can be penetrated by a beam of light, sound, particles, or other energy or matter. A coefficient value that is large represents a beam becoming 'attenuated' as it passes through a given medium, while a small value represents that the medium had little effect on loss.
Cutoff (physics)         
In theoretical physics, cutoff (AE: cutoff, BE: cut-off) is an arbitrary maximal or minimal value of energy, momentum, or length, used in order that objects with larger or smaller values than these physical quantities are ignored in some calculation. It is usually represented within a particular energy or length scale, such as Planck units.

Cutoff (physics)

In theoretical physics, cutoff (AE: cutoff, BE: cut-off) is an arbitrary maximal or minimal value of energy, momentum, or length, used in order that objects with larger or smaller values than these physical quantities are ignored in some calculation. It is usually represented within a particular energy or length scale, such as Planck units.

When used in this context, the traditional terms "infrared" and "ultraviolet" are not literal references to specific regions of the spectrum, but rather refer by analogy to portions of a calculation for low energies (infrared) and high energies (ultraviolet), respectively.
