Coherence, английский
- Соответствие; согласованность
- Lasers and leds emit coherent light waves that are in phase with one another. describes properties of the correlation between a single wave, or between several waves or wave packets. when interfering, two waves can add together to create a wave of greater amplitude than either one (constructive interference) or subtract from one another to create a wave of lesser amplitude than either one (destructive interference)
- A property of electromagnetic waves which are in phase in both time and space. coherent light has monochromaticity and low beam divergence, and can be concentrated to high power densities. coherence is needed for interference processes like holography.
- The alignment between light wave wavelength and the position of that wave in its oscillation cycle. when the crests and troughs of several light waves are in alignment, they are coherent. collimated light
- A fixed phase relationship between the electric field values at different locations or at different times
- И coherency
Coherence area, английский
Coherence du sol, французский
Coherence effect, английский
Coherence extender, английский
Coherence length, английский
- A measure of temporal coherence, expressed as the propagation distance over which the coherence significantly decays
- That length over which energy in two separate waves remains constant. with respect to a laser, the greatest distance between two arms of an interferometric system for which suficient interferometric effects can be obtained.
Coherence length extension, английский
Coherence time, английский
A measure of temporal coherence, expressed as the time over which the field correlation decays

Theory of architecture, английский
Theory of contestable markets, английский
A theory that holds that potential competition can have an impact on price similar to when there are a large number of firms in the market. even though one or a few suppliers are currently in the market, market power is constrained by the threat of entry—if entry barriers are, indeed, low.
