The phrase "a significant decrease in the coefficient" is correct and usable in written English.
It can be used in contexts such as statistical analysis, research findings, or discussions about mathematical models where changes in coefficients are relevant.
Example: "The study revealed a significant decrease in the coefficient, indicating a strong reduction in the correlation between the variables."
Alternatives: "a notable reduction in the coefficient" or "a marked decline in the coefficient."
In the absence of flow the liner reacts classically: there is a significant decrease in the transmission coefficient around the frequency of minimal impedance.
A significant decrease in the diffusion coefficient from stage II to stage III was observed, which is believed to be the consequence of crystallization of fibers as a result of long-term incubation in an aqueous solution.
The sudden increase in the film thickness after the hydraulic jump leads to a significant decrease in the heat transfer coefficient.
Introduction of carbon nanotubes to the aluminium matrix causes a significant decrease in the thermal expansion coefficient αz(T) as a function of temperature along the direction perpendicular to the rolling plane of the nanomaterial ribbon.
A significant decrease in the wear rate and coefficient of friction (CoF) was achieved at high temperatures (750 °C) and was maintained as a result of the storage of the Ag3VO4 phase in the dimples.
A significant decrease in the friction and wear coefficients was achieved with CrAlN single and multi-phase films compared to the CrN-based counterpart.
However, there was a significant decrease in the EC50 value (p-value = 0.008) and a significant increase in the Hill coefficient (p-value = 0.003).
