The phrase "an obvious size" is correct and usable in written English.
It can be used when describing something that is clearly or evidently large or small in dimension.
Example: "The box was of an obvious size, making it clear that it contained multiple items."
Alternatives: "a noticeable size" or "a clear size".
It is found that under the same load, the average friction forces per atom are smaller for a bigger graphene flake, which exhibits an obvious size effect.
And as mentioned before, the constriction resistance has an obvious size effect, which decreases from 4.505 × 108 to 9.897 × 106 K/W with the increasing width, and it is almost inversely proportional to the width of the constrictions.
However, also here, the recovery varied from 38 to 96%%, without an obvious size dependency (Table 1).
However, the specific cutting force increases rapidly with the decrease of cutting depth, which shows a very obvious "size effect".
The test observations indicate the existence of size effect in relatively larger-sized moderate high-strength RC columns under both monotonic and cyclic axial compression, and the RC columns under cyclic loading pronounce a more obvious size effect.
For the in vitro verification of the size effect on endocytosis tested after 1 or 4 h co-incubation, a more obvious size effect-induced difference on cellular uptake was detected that Au/PAMAM with small sizes tended to uptake more than others (Fig. 3d).
As shown in Figure 3, for a mixture of particles with obvious size difference (bimodal distribution), the calculated Z-average carries irrelevant size information.
The obvious size difference in a man can be intimidating to a toddler.
In related researches for ZnO, our data is different from the report [28] that E2 mode displays no obvious size dependence within a diameter range of 5.7 500 nm.
It is also noted that there is an obvious indentation size effect on the tests of elastic modulus E and hardness H, where the measured value decreases with the indentation depth in the nanoscale.
As a result, in this case of cultivated rice, there was an obvious population size expansion.
