The phrase "additive level" is correct and usable in written English.
It can be used in contexts related to mathematics, statistics, or any field where levels of addition or accumulation are discussed.
Example: "The additive level of the components in the mixture must be carefully calculated to ensure the desired outcome."
Alternatives: "cumulative level" or "aggregated level".
MoOx additive level was carefully controlled by monitoring the active Pt area by cyclic voltammetry.
This work also showed that ink-jet printing was a convenient and low-cost method to prepare gas-sensing films with controlled film thickness and additive level.
The present study revealed the importance of stringent controlling of the additive level for maintaining a balanced bifunctional behavior of the catalyst combination through the synergistic effects by the components and the need of a proton conducting membrane operable at high temperature to get better output from the Polymer Electrolyte Membrane Fuel Cell (PEMFC) systems.
The additive level was varied from 0 to 40 % over a C/O ratio of about 28, a riser outlet temperature of 566 °C, a riser partial pressure of 0.0793 MPa, and a contact time of 1.5 s.
As a result, the root mean squared measurement error (‖ Y − Y ^ ‖ 2 ) approximately followed the additive level of measurement noise.
The corresponding RERI was 0.78 (95% CI: 0.48, 1.08), indicating a synergy or positive interaction on the additive level.
These models can be used to predict dough and bread properties when additive levels are known.
The parallel preconditioner, called the block complement and additive levels method (BCALM) preconditioner, is based on treating pressure unknowns separately from the velocities and gradients.
The bulk crystallization of paracetamol has been examined under controlled conditions in the presence and absence of the additive p-acetoxyacetanilide (PAA), as a function of both supersaturation and additive levels.
It is demonstrated that for such an inhibitor in a stoichiometric methane/air flame, additive levels in the 0.001 0.01 mole percent range will lead to a decrease in flame velocity of approximately 30%.
Only the additive levels of sensation seeking was positively associated with boys' problem behaviors.
