The phrase "air background" is not a standard or commonly used expression in written English.
It may be used in specific contexts related to sound design, audio production, or environmental descriptions, but it is not widely recognized.
Example: "The film's sound design included an air background that created a sense of openness and tranquility."
Alternatives: "ambient background" or "atmospheric background".
§ 1066.610 Dilution air background correction.
The photonic crystal is consisted of pillars on air background in hexagonal lattice.
The geometry of photonic crystal is pillar-based in the air background with a square lattice.
The designs are built using 2D square lattice Photonic Crystal (PhC) structure of dielectric rods embedded in air background.
The thermal effects on the refractive direction of a sonic crystal consisted of steel rods in air background is investigated.
Moreover, at certain frequencies and incident angles, the refractive angles can be changed from negative to positive by varying the temperature of a sonic crystal with air background.
In [ 14], Lou et al. proposed an algorithm for mass segmentation and the algorithm is based on the assumption that the trace of intensity values from the breast region to the air-background is a monotonic decreasing function.
In Didion's world, how we experience news is how we experience the world and that is why the temperature of the air and background music in the bar can seem inseparable from our experience of the event.
We then extrapolated these estimates to previous years, adjusting for changes in air pollution background and work-related exposure conditions over time, to derive monthly EC estimates from 1971 to 2000 for each job and terminal location.
In addition to the thick and thin base plate samples, diffraction data were collected on α-chitin and chitosan reference materials (Deschamps 2013) as well as an air scatter background image.
To derive monthly EC estimates from 1971 to 2000 for each job and terminal location, we adjusted for changes in air pollution background and work-related exposure conditions over time.
