The phrase "air reduction" is correct and usable in written English.
It can be used in contexts related to environmental science, engineering, or processes that involve decreasing the amount of air or oxygen in a system.
Example: "The air reduction process in the furnace improved the efficiency of the combustion."
Alternatives: "decrease in air" or "reduction of air".
Advantages of air reduction in SOE operation stand in both capital and operation costs.
Due to air reduction, oxygen concentration of off gasses was increased from 25% up to 50%.
Additionally, as valve clearance or cam rotation speed becomes larger, the valve lift and the working phase decrease, which eventually leads to inlet air reduction.
The improvement in this arrangement is attributed to the better utilization of available compressed air, reduction of axial air penetration and minimization of water reverse flow in the riser pipe.
The child who died during the study period had undergone air reduction and had recovered from IS.
Strikingly, all this cost accounting totally ignores the potential benefits of new rules -- clean air, reductions in work hours lost to injury or illness, safe financial markets, business opportunities, so on - a sharp departure from the cost/benefit approach taken by earlier reforms and making it far less "public interest" friendly.
A uniform density of 2.67 g/cm3 and a constant vertical gradient value of −0.3086 mgal/m were assumed for the Bouguer density and free-air reduction, respectively.
The procedure involves a calculation scheme with formulations for normal gravity, free-air reduction, atmospheric correction, lithospheric correction, and Bouguer correction (Komazawa 1998).
The other applied reductions include a secondary indirect topographical effect (Vaníček et al. 1999), a second-order free-air reduction (Heiskanen and Moritz 1967), and an atmospheric correction (Wichiencharoen 1982a).
The free-air gravity anomaly used in this study is computed as, (5) where gob is the observed gravity, δgfa is the second-order free-air reduction (Heiskanen and Moritz, 1967), δgac is the atmospheric correction (Wichiencharoen, 1982a), and γ is the normal gravity on the reference ellipsoid.
Studies that have quantified the health benefits of air pollution reduction have often concluded that mortality reduction is the largest contributor (Hubbell et al. 2005).
