It can be used when describing a gradual reduction in quantity, quality, or intensity of something.
Example: "There has been a slow decrease of the population in the rural areas over the past decade."
Alternatives: "a gradual decline in" or "a steady reduction of".
However, a slow decrease of methane conversion and syngas yield caused by carbon deposition was observed.
We observed a slow decrease of the impedance in all the electrodes, except in the wire electrode.
In this case, we choose in addition a relatively small value of parameter γ to impose a slow decrease of the global variable σ.
Alternatively, results due to allelopathy show a slow decrease of yield or even increase in yield as density increases, until density reaches a point where resource competition among neighbouring target plant becomes the dominating factor.
A relatively rapid increase in R ct is observed for DNA hybridization with the probe-DNA attached directly to the gold surfaces compared to a slow decrease of R ct with time when the probe-DNA is attached to VASWCNTs, which is evident from the combined plot of R ct against time in Fig. 7.
The voltage decreased from 0.27 to 0.22 V during the first 80 min and was then quasi-stable, with a slow decrease of 9 mV h−1.
However, Dirkzwager et al. found a slower decrease of sick-leave (6 months) after an explosion in the Netherlands in 2000 [1].
Figure 3 thus suggests an initially higher risk, followed at first by a sharp and later by a slower decrease of risk.
Patients with [P(cv-a CO2] cv-a CO2]an 6 mmhigher a lower cardiac index, a larger clearance of lacthan, and a slower decrease of SOFA score in the first 24 h than patients with a [P(cv-a)CO2] lower than 6 mmHg [15].
Consequently, this fraction of the photosynthetic apparatus works against the larger combined cytochrome c2 pool of the photosynthetic and respiratory pathways, leading to a slower decrease of the cytochrome c oxidation.
Remarkably, there is a slower decrease of T cells compared with age-related control individuals [ 43].
