Ultraviolet degradation, английский
Weakening or deterioration caused by exposure to ultraviolet rays of sunlight or artificial light.

Actinic, английский
- With respect to radiation, the characteristic that indicates capability to produce chemical change, as in the photographic activity of light. electromagnetic energy that is capable of producing photochemical activity
- Optical energy that is absorbed by radiation-sensitive coatings to produce an
Actinic glass, английский
A glass having a yellow tint which reduces the transmission of infrared and ultraviolet rays; sometimes used in factory windows or skylights.
Actinic resistance, английский
Ultraviolet resistance
Degradation, английский
- Dégradation
- The progressive failure of a machine or lubricant.
- Disintegration of a paint film by heat, moisture, sunlight, or natural causes.
- Debasement and disgrace. the suspension of a petty officer from his station; and also the depriving an officer or soldier of his arms previous to his being delivered over to the civil power for execution.
- In computer systems, a reduction in level of performance or service. degradation in microcomputer performance is indicated by slow response times or frequent pauses for disk access because memory is insufficient to hold an entire program plus the data the program is using.
- The loss of desirable physical properties by a textile material as a result of some process or physical/chemical phenomenon.
Degradation, английский
Degradation factor, английский
Коэффициент снижения производительности; степень деградации
Degradation failure, английский
Постепенный отказ
Degradation mechanism, английский
Механизм ухудшения характеристик
Degradation of cellulose, английский
Degradation of radar defense system, английский
Система постановки (активных и пассивных) радиолокационных помех
Degradation product, английский
Degradation screens, английский
Degradation vacuity, английский
The space-time value o f the degradationally removed part o f a transgressive-regressive depositional succession; the part o f a lacuna resulting from the degradation o f formerly existing rocks at an unconformity (wheeler, 1964, p. 602).
Degradation [geomorphology], английский
The wearing down or away, and the general lowering of the land surface by natural processes of weathering and erosion (e.g., the deepening by a stream of its channel) and may infer the process of transportation of sediment. compare - destructional. gg
Degradation, image quality loss, английский
Loss of image quality or definition for any number of reasons including intentional ones. quote: i don`t like forced development and flashing. because i do like a fairly rich negative with good blacks, i`m not keen on the strong use of fog filters, although on occasion i use them. i don`t like the effect they produce. [also] you`re going to have to make a dupe negative. so you`re into a degradation with the dupe. then any opticals . . . give you further degradation. then . . . the projector is not so good; it hasn`t got a very sharp lens or there`s not enough light. at every stage along the line, the picture`s going to deteriorate . . . so i`m very reluctant to have a degraded negative in the first instance. i think you`re cheating your audience. they`ve got a right to see what`s on the screen. - billy williams [ml].
Degradative ability, английский
Способность разлагать
Ultraviolet, английский
- Electromagnetic radiation at wavelengths shorter than the violet end of visible light
- Ultraviolet. the electromagnetic radiation with wavelengths shorter than about 400 nm and not visible to the human eye.
- Ультрафиолетовый
- Invisible electromagnetic radiation defined between 100 and 380nm.
- The part of the electromagnetic spectrum that falls just below visible violet. ultraviolet (uv) coating – a coating that blocks out uv radiation up to 380+ nanometers.
- Electromagnetic radiation in the wavelength range of 4 to 400 nanometers.

Ultraviolet resistance
Twist bleed, английский
- Twit
- Twist, direction of: the direction of twist in yarns and other textile strands is indicated by the capital letters s and z
- Yarn has s-twist if when it is held vertically, the spirals around its central axis slope in the same direction as the middle portion of the letter s, and z-twist if they slope in the same direction as the middle portion of the letter z
