"the difference diminishes" is grammatically correct and can be used in written English.
You can use this phrase when describing a situation where the gap or distinction between two things is becoming smaller or less significant. Example: "As you move closer to the equator, the temperature difference between day and night diminishes."
The difference diminishes, however, in the next groups, and many authorities do not agree that germanium is more electronegative than silicon, although an abundance of chemical evidence appears to indicate that this is so.
The difference diminishes at the position about 2.5 nm to the indenter tip, in which all three indentation speeds have approximately the same normal force.
The corresponding energy gaps are about 1 eV wider than those of the bare nanoribbons, and the difference diminishes with width increase [13].
For requests of Type 3 the differences are also large when the substrate is largely available, although the difference diminishes as the substrate becomes saturated.
Similarly, replacement of fine clinker particles with slag decreases 12-h heat more than replacement of intermediate particles but the difference diminishes beyond about 24 h.
Although the difference diminishes at higher energy, the x-rays used for diffraction have photon energies of typically 1 to 10 keV, whereas the electrons that needed to penetrate even a thin (<1 μm) specimen have kinetic energies of tens or hundreds of keV.
An independent analysis of randomized studies comparing IF using volar locking plates with EF showed that at 3 and 6 months, the volar plate group had better DASH scores, but the difference diminished over time; at 12 months, the scores were not statistically significantly different and showed a trend in favor of EF (Table 3).
However, when comparing with the results obtained in the first research cycles, i.e., the traditional approach vs. the original VISOLE approach (Jong, 2015), we found that the difference diminished considerably (see the illustration in Fig. 2).
The difference diminished after the sixth postoperative day (P < 0.03).
However the difference diminished after adjusting for low back pain.
The difference in urine output between the groups was largest 4 h post-transplant (p = 0.001), later on the difference diminished.
