From Figure 4 b, the friction coefficients μ of the ASW and PBS are only 0.261, 0.183 and 0.160 in air, and show a decreasing trend.

Even so, the Zn–Mg alloy group demonstrated enhanced proliferation compared with the control group at day 3, while no obvious difference was apparent when comparing pure Zn with the control group.

However, there were more significant differences in shear stiffness, and the shear stiffness of the specimens showed a decreasing trend after freeze–thaw cycles; this was due to the damage of the bonding surface caused by the freeze–thaw cycles, resulting in a decrease in the bond strength, and at the same time, the slippage between the steel pipe and the concrete increased; the shear stiffness of the specimens showed an increasing

However, there were more significant differences in shear stiffness, and the shear stiffness of the specimens showed a decreasing trend after freeze–thaw cycles; this was due to the damage of the bonding surface caused by the freeze–thaw cycles, resulting in a decrease in the bond strength, and at the same time, the slippage between the steel pipe and the concrete increased; the shear stiffness of the specimens showed an increasing trend with the increase in concrete strength, which was due to the improvement of concrete strength that increased the mechanical bite force between concrete and steel tube, thereby improving the bond strength of the steel tube push-out specimen and reducing the slip between the concrete and steel tube.

Highly significant effects on interactions and properties, such as solubility of cellulose structures, are expected.

found that the freeze–thaw splitting strength ratio of hot rejuvenated asphalt mixtures (HRAM) presented a decreasing trend with the increase in RAP content [ 7 ].

Therefore, the COF sees a decreasing trend with the increasing temperature.

The results show that the oil film decreases gradually with increasing temperature; the lubrication state finally changes from hydrodynamic lubrication to dry friction, where the friction coefficient shows an increasing trend before a decrease.

The changes in the surface roughness were observed for varying erodent velocities, and they showed an increasing trend.

Unexpectedly, an increasing trend is shown in the elongation at break ( Figure 6 b).

When the ratio of the shear stiffness to bending stiffness is large, the unit cell has a strong shear resistance and the shear deformation does not have an extremely significant effect on the deformation mode of the structure.

First, an increasing trend moving from the no-coating case to the carbon and then graphene is observed for both the used methods.

For higher reduction levels, values resume an increasing trend, with a slope similar to that previously observed.

The dry density of the two different specimens shows an increasing trend as the vibratory force rises from 700 N to 1400 N, but the dry density growth rate of the specimen with G / S = 1.6 is lower than that of the specimen with G / S = 1.6 M.

In this study, a small dataset was used and the added time for preprocessing was not noticeable, but for larger datasets, this might be significant. 3.3.2.

As one can see, the appearance of the MA + SPS alloys did not undergo any extremely significant change compared to the previously shown micrographs of the MA + SPS compacts (see Figure 7 ).

Although the thermal conductivity of insulated concrete showed an increasing trend with increasing temperature, the increase was minimal.

A decreasing trend in capacity was observed with increasing Al content, which might be related to the fact that Al does not have a high affinity for hydrogen compared to Ti/V/Nb which are hydride-forming elements [ 30 ].

Moreover, the flow stress always showed an increasing trend with the increase in strain, and no obvious peak stress appears when the hot compression temperature is 1273 K as shown in Figure 2 a.

Furthermore, the normal stress could be divided into three stages: a steady value, then an increasing trend and finally a gradual decline, which possibly results from the complex transformation of the internal microstructures of MRG.

There are only minor differences in the extracted short-range order structures; for example, in an overall trend, the distances are larger for sample A compared to samples O and W, while the intensity of the features (S 0 2 ) is maximal for sample O, i.e., the preparation in 1-octanol.

As the size increases, the r value corresponding to the descending mutation point of the specimen indicates an overall increasing trend, whereas the descending mutation amplitude of the r value indicates a decreasing trend.

Meanwhile, the DIC results show that as the specimen size increases, the peak principal strains (corresponding to the principal strains in the red region) of the specimens are 1.51%, 3.89%, 5.68%, and 9.28%, showing an increasing trend.

These results, therefore, do not make it possible to extract a clear trend as to the effect exerted by the additions of natural pozzolans.

Similarly, a quantitative comparison was also carried out to evaluate the relation between the depth of cut and the maximum depth of subsurface damage, and the result is shown in Figure 11 , where the maximum depth of subsurface damage shows an increasing trend with the increase in the depth of cut.
