The phrase "acceleration period" is correct and usable in written English.
It can be used in contexts related to physics, economics, or any situation where a phase of increasing speed or growth is being discussed.
Example: "During the acceleration period of the project, we saw significant improvements in productivity and efficiency."
Alternatives: "growth phase" or "speed-up phase".
The experiment results indicate that both LSA-1 and LSA-2 can accelerate the hydration rate by advancing the hydration acceleration period and result in the earlier generation of Ca(OH 2 and AFt.
Moreover, hydration of clinker in the acceleration period is increased by aphthitalite.
The same idea is being applied to cycling, where things like acceleration period or those pesky traffic lights are taken into account.
For those who'd like to get in on the action next time round, applications will be opened in September 2012 for the December-March acceleration period.
The results showed that the synthetic C-A-S-H shortened the setting time, promoted the formation of an acceleration period at an early stage, and increased the hydration heat released during the acceleration period.
For structures with periods on the descending branch of the spectral acceleration period plot, this may result in some structural base shears being slightly overestimated.
Moreover, the acceleration periods of the fault slip corresponded well with increases in the background seismicity for shallower earthquakes.
In other words, when ∆ω and dω/dt have the same signs in segments ① and ③, they are acceleration periods.
It is indeed impossible to assert that our SV model obtained for quiet acceleration periods (not low acceleration but of negligible variation) will represent well near-future time evolutions of the core field.
The results indicated that the hydration process could be accelerated at the beginning by addition of silica fume, and fly ash, on the other hand, retarded hydration mainly in the dormant and acceleration periods.
Seismic performances were determined based on monitoring the system's plastification and analyzing the relevant parameters for the level of target displacement, such as target displacement, total shear force, spectral displacement, spectral acceleration, vibration period, damping and ductility.
