The phrase "a width variation" is correct and usable in written English.
It can be used when discussing differences or changes in width, often in contexts related to design, manufacturing, or measurement.
Example: "The fabric has a width variation that affects the overall appearance of the garment."
Alternatives: "a width difference" or "a width change".
All are heavy-tailed (sparse) and symmetric distributions, with a global shape for all dimensions, but an allowable width variation described by the covariance structure matrix.
While increasing the magnetic field, a paradoxical sheath width variation was observed.
Through optimizing growth conditions, a wide wavelength shift of over 80 nm with a rather small mask width variation (0 30 μm) is obtained.
Recently OMRI was successfully applied to in vivo oxymetry imaging by correlating the Electron Paramagnetic Resonance (EPR) line width variation of a trityl free radical to oxygen concentration [20].
By applying a stress field on crystalline sample and monitoring the peak width variation of different hkl diffractions as a function of pressure, one can derive the differential strain, thus the constitutive properties of the sample materials.
Additionally, macro-crack width variation in coating shows a similar trend with surface strain distribution.
The analysis of the crack width variation within the depth of a reinforced concrete structure is difficult to perform.
Line width variation of the pattern of an as-deposited film was improved to be well below the electronics design rule, 5%.
In this study, drop strings of different spacing were investigated in a high-temperature oxidizing environment for their flame transition, flame width variation and drop evaporation rate.
A model containing only HbA1c accounted for 4.7% of GBM width variation, with the total variability explained by the model increasing to 11.6% when MGHI, CEL, and CML were added to the regression model (7.9% increase).
