"constant contribution" is a grammatically correct phrase and is commonly used in written English.
It means a continuous or persistent contribution to something. Example: The success of the project was due to the team's constant contribution and dedication.
His solution was reliance on the "independent nuclear deterrent", initially entrusted to the V-force of Valiant, Victor and Vulcan bombers, which for 27 years, in Hubbard's view, "made a constant contribution to the maintenance of world peace".
In the mid-1980s the substitution dynamics was replaced by a relatively constant contribution from oil, natural gas, coal, nuclear power, and hydropower.
It can clearly be seen that there is the constant contribution from the carrier frequency and - as the interesting part - a slow oscillation of angular frequency μ that stems from sin ( μ z + const ).
For the electronic dielectric constant contribution, it was calculated using density functional perturbation theory at the DFT/PBE level of theory and at the experimental geometry, as well as by employing the QE code.
The substrate itself causes a space charge effect which adds to the overall conductance as a constant contribution and is of the order of the effect of a single CaF2/BaF2 interface (or less), and hence totally negligible if the number of CaF2/BaF2 interfaces is high.
The majority of the metabolites that had a constant contribution to treatment differences over time (categorized as response type A) showed a decreased concentration in plasma in response to diclofenac treatment compared to subjects treated with placebo.
And a news release that compares two completely incomparable figures — the change in stock prices and the change in balance in an investment account that gets constant contributions — to falsely imply that 401(k) plans have been outstanding performers.
The total PAPR can be obtained from this figure by adding 1.05 dB, for the APSK, and 2.55 dB, for the QAM, that are the constant contributions due to the constellation.
We have considered two scenarios, isolation of a hybrid population after its founding, and constant contributions from source populations to the hybrid population over time.
Third, with constant contributions at each generation, the starting conditions influence the speed with which the distribution of admixture tends toward its long-term distribution, but do not predict the qualitative form of this distribution.
In Figures 2, C E, we consider admixture scenarios in which the founding of the hybrid population is followed by constant contributions from the source populations over time, s1 = 0.1 and s2 = 0.3.
