The phrase "addition to the constant" is correct and usable in written English.
It can be used in mathematical or scientific contexts when referring to a value that is being added to a fixed number or constant.
Example: "In the equation, we need to make an addition to the constant to adjust the results."
Alternatives: "increment to the constant" or "supplement to the constant".
The rev of their motors, even at a distance, was a regular addition to the constant soundscape of helicopters and sirens.
In addition to the constant shelling by artillery, tanks, and sniper-fire, civilians have had little access to water and no electricity for many days — both supplies had been cut off by the government — and food and medicine were scarce.
Column 5 was tested under pure torsion (T/M = ∞) in addition to the constant axial load.
Column 1 was subjected to cyclic uniaxial cantilever bending and shear (T/M = 0) in addition to the constant axial load.
On annealing, the second lower melting temperature which increased linearly with the annealing temperature appeared in addition to the constant high melting temperature.
That's because the act of blinking effectively milks your meibomian glands, causing a little bit of extra meibum to be expressed onto your eye in addition to the constant, steady secretion of the stuff.
In addition to the stability constant data, the kinetic data for Fe'L (Table 1) reflect the fast reaction rates via kf and slow dissociation rates via kd.
Therefore, in addition to the baseline constant injection rate, two simulation runs with α = 1 and α = 2 have been executed by Thiele and Batycky approach.
Another explanation may be that the experimentally determined V influx and V efflux (under zero-trans condition) also include other terms in addition to the rate constant of the rate-limiting step such that Eq. 19 was not true.
In addition to the relatively constant concentrations of P extracted at the initial pH with the anion sink, moderate acidification to pH 6.5 released 9% of the reserve-P in the high P soil, but this varied from 18 to 33% in the two other soils containing lower soil P.
Therefore, the general strain gradient elasticity theory contains only three independent material length-scale parameters for isotropic materials in addition to the Lame constants.
