The phrase "a decrease in the length of" is correct and usable in written English.
It can be used when discussing a reduction in size or measurement, particularly in contexts such as science, engineering, or general descriptions of change.
Example: "The experiment showed a decrease in the length of the material after exposure to high temperatures."
Alternatives: "a reduction in the length of" or "a shortening of".
"This would mean a decrease in the length of the day, with the corresponding rise in tempo of many human activities, if any still persisted!
Higher magnetic field strength is expected to afford higher spatial resolution and/or a decrease in the length of total scan time due to its higher signal intensity.
A decrease in the length of (B_{text{f}}), due to a change in the middle leg's position, causes an increase in the amount of the tension and compression, and vice versa.
A decrease in the length of (B_{text{f}}), due to a change in the middle leg's position towards the front, causes an increase in the tension and the compression magnitude in the front and middle legs, and vice versa.
Thus, these results show that the dense panicle phenotype of smg11 was due to a decrease in the length of panicle axis and increases in the secondary panicle branch number and grain number per panicle.
The results showed that the average velocity of the fluid increases with an increase in the heating power and aspect ratio or a decrease in the length of the cooling section.
There was a decrease in the median length of stay post-intervention (p = 0.03).
CFI was associated with a 90% decrease in serious complications and a 20% decrease in the length of hospitalization.
In contrast, previous meta-analyses failed to demonstrate a decrease in ICU length of stay.
This mechanism would involve increases in the length of short, and decreases in the length of long tandem repeats [ 40].
An increase in the perimeter length therefore represents a decrease in the roundness of the particle.
