The phrase "at acceleration" is not commonly used in written English and may not be correct depending on the context.
It could be used in technical or scientific contexts where acceleration is being discussed, but it typically requires additional context to clarify its meaning.
Example: "The vehicle's performance improves significantly at acceleration beyond 60 mph."
Alternatives: "during acceleration" or "while accelerating".
Si substrates were irradiated with the Ar cluster ions at acceleration energies between 20 and 80 keV.
The most regular structures appear at acceleration voltages higher than 20 kV and areal dose ranges of 350 450 μC/cm2 with lower scanning speeds.
The results are mixed: While the C70 holds its own in track testing against similarly priced rivals, excelling at acceleration and road-holding tests, it can feel unpolished on real-world byways.
The set-up allows to conduct implantation of ions of various materials with an implantation current of 100 μatcm2 accelerationion voltage of up to 30 kV.
Au films were also irradiated at acceleration energies between 20 and 80 keV and the surfaces were observed with Atomic Force Microscopy (AFM).
Especially at speeds below 60 km/h and at idling, but also at acceleration conditions for a wide range of speeds, traction noise can be dominant.
"Then it travels along thirty feet of path at one thousand three hundred and fifty millimetres per second, changing speed and direction at accelerations reaching 3g".
Plethodontid salamanders, on the other hand, project their tongues at accelerations up to 4,492 m s−2 (458 g) and power output values as high as 18,129 W kg−1 34.
So powerful is its suck that prey enters its mouth at accelerations comparable to those of rocket-powered cars.
The acrobatic migratory birds rocket over bridges and skim over lakes, careening around each other at accelerations that would knock an Air Force ace out cold.
A 1,500kg car accelerates at constant acceleration from rest to a velocity of 12 metres per second in 4 seconds.
