The term "ageing rate" is a correct and usable term in written English.
For example, you could say, “If we don't make changes to our pension plans soon, our ageing rate will continue to climb.”.
An ageing study realised at 700 °C for 320 h showed an ageing rate of 0.125% h−1.
The rate and shape of the charging current indubitably affect the charging time and the ageing rate of a battery.
Neither the ageing rate nor the shape of the distribution of retardation times are affected by temperature.
At low stresses, though the material exhibits strong non-linearity, the ageing rate μ is found to be independent of stress.
In contrast, creep measurements showed a slight decrease in the horizontal shift rate, μh, upon stretching (i.e. a decreased ageing rate).
In general, the bio-oil quality in terms of the solids content, ash content, initial viscosity, viscosity change and ageing rate could be enhanced by the hot vapour granular filtration.
Physical ageing rates were then measured as a function of orientation with dilatometry and tensile creep measurements.
The purpose of the chosen diversity was to establish the possible spread in the ageing rates generated by different architectures.
The effects of different device architectures and encapsulation techniques on ageing rates of the samples were also studied.
Increasing the cooling rate prior to aging increases the aging rate.
In physically and healthily compromised individuals, deviation from normal aging rate may be observed.
