The phrase "a decrease in the width of" is correct and usable in written English.
It can be used when discussing changes in dimensions, measurements, or physical properties in various contexts, such as science, engineering, or design.
Example: "The experiment showed a decrease in the width of the sample after the treatment was applied."
Alternatives: "a reduction in the width of" or "a narrowing of".
This decrease may correspond to a decrease in the width of fracture apertures in the fractured granite, or their closure.
Indeed, this is equivalent with a decrease in the width of double layers, while the amplitude of the produced double layer remains unchanged.
Two-step aging causes a decrease in the width of precipitate-free zones in the large-particle specimen, resulting in the improvement of fatigue life.
It should be noted that at this story level there is a decrease in the width of the columns by 5 cm as well as a decrease in reinforcement ratio for most of the columns.
An increase in the amplitude of the composition fluctuation and a decrease in the width of the interface between Cu-rich and Ta-rich regions are observed in the proximity histograms as phase separation progresses.
According to the results of measurements of low-field magnetic susceptibility (χ/χ mах) of Cu-Al-Mn alloy at different regimes of aging (see Fig. 4), there is a slight increase in the start temperature (M s) of direct β1↔β′ transformation after annealing in magnetic field and a decrease in the width of MT temperature hysteresis (ΔT).
For the body, this indicates initial expansion in outer width, followed by a decline towards original width, accompanied by decrease in the width of the inner body such that in all stages of decay there is a similar separation between epidermis and the outer cuticle.
One can note an increase in intensity and a decrease in width of the reflexes with increasing the irradiation power.
After 1 year, patients on TNFαi showed partial recovery in terms of a decrease in the mean depth of erosions while the mean width remained the same.
A positive (negative) correlation results in a decrease (an increase) of the width of the pressure distribution.
The displacement also decreases with decreasing the width of the trench while increasing with decreasing the width of the low-k wall.
