The phrase "a combination of thickness" is correct and usable in written English.
It can be used when discussing the varying levels or measurements of thickness in a particular context, such as materials or design.
Example: "The final product features a combination of thickness that enhances its durability and aesthetic appeal."
Alternatives: "a blend of thickness" or "a mixture of thickness".
For example, Ohayon et al. [ 28] has demonstrated that plaque instability is affected by a combination of cap thickness, necrotic core thickness and the arterial remodeling index.
We believe that the greater average perimuscular connective tissue thickness and echogenicity in the LBP group likely reflects a combination of increased thickness and increased numbers of connective tissue layers in subjects with LBP.
Hence the passage of melt water through the snow pack is not uniform [ 37] and a combination of snow thickness and route of percolation of liquid phase water through the snow pack will influence the development of potential surface ice layers.
In particular, a combination of small cavity thickness and a high mold temperature (above Tg) can be effective in increasing the replicated height of micro-features.
The macroscopic compression behavior of flexible graphite is attributable to a combination of bending and thickness reduction/recovery of the discs.
Galvanizing protocols may be tailored to achieve a combination of intermetallic layer thicknesses that enhances the coatings' crack resistance.
A combination of AUB presence/absence and thickness allowed the best accuracy (AUB + thickness ⩾3, ⩾4 or ⩾5; sens.=100, 81.6 or 91.6%; spec.=22.8, 40.4, or 56.7%).
The rate of band evolution after shear was quantified consistently in terms of the time taken for the average band spacing to reach a minimum, and was found to depend on a combination of prior shear rate, specimen thickness, solvent type and concentration.
This resulted from a combination of increased implant diameter and thickness of the implant walls.
The effects of STs were evaluated by growth rate (GR) analysis using a combination of growth time (GT) and thickness evaluated by XRD and XRR measurements.
