However, the yield strength and ductility of these as-cast MEAs exhibited an increasing trend when their Zr content was increased.

Although the electrical properties significantly changed with respect to the In concentration, an apparent trend depending on the In concentration was not observed in the structural properties of the IZO film.

Moreover, with an increase in the stirrup strength, the increase in the ductility coefficient of the SRHC columns shows a decreasing trend.

This is also supported by the relative span factor shown in Figure 11 , which does not show an increasing trend as the power increases.

With the increase of the emulsifier content, all three action energies showed a trend of first increasing and then decreasing, i.e., the stability of biomass asphalt/water emulsion would become stable at the beginning due to the reduction of interfacial tension by the emulsifier, but when the amount of emulsifier further increased beyond the so-called critical micelle concentration, the whole system would become unstable.

When the dry density is the same, with the increase of water content, the grouting quantity also shows a decreasing trend.

The significance tests of the three models were p < 0.001, indicating extremely significant and high reliability of the three models.

However, in recent years, there has been an increasing trend in producing different zirconia objects thought AM techniques (3D printing) [ 16 ].

With increasing water erosion time, the crush resistance of steel slag before and after treatment showed a decreasing trend, but the abrasion and crush value of treated steel slag gradually became stable.

For instance, the temperature difference at different speeds was in the range of 12.3–17.9% and showed an increasing trend with increasing speed.

The friction coefficient analysis at the tool–chip interface at different cutting speeds indicated a decreasing trend of friction coefficient in the order of AS (conventional), AT-PE (linear grooves perpendicular), AT-PA (linear grooves parallel) and AT-W (wavy grooves) tools, Figure 6 .

Therefore, I OFF exhibits an increasing trend.

With increasing strain rate, the DRX grain size decreased rapidly, while the DRX volume fraction showed a trend of first increasing and then decreasing.

(2) The strain rate sensitivity of 316L exhibits an interesting trend, in that it is generally low (0.1–0.2) at 700–900 °C but increases to 0.33, at 45% strain at 1000 °C.

However, at 1000 °C, there is an increasing trend for the strain rate sensitivity, which increased from 0.15 at a strain level of 20% to 0.33 at a strain level of 45%.

A negative trend in OCP with time (towards more negative values) indicates a tendency for the metal/surface to corrode in the solution, while a less negative OCP (reverse trend) indicates a low tendency for corrosion, indicates the formation of a protective layer (passive layer), or demonstrates the stability of the previously formed protective layer. 3.2.1.

The resistance values for all modified surfaces showed an increasing trend.

The adsorption capacities of Zn−AC, Cu−AC, and Fe−AC showed a decreasing trend with the increase in the initial pH value.

Nevertheless, the data obtained were very scattered and did not show a pronounced trend across the impactor plate series.

Comparing the parameters controlling the flushing mechanism, an increasing trend is visible where the spark gap increased with the increase in the magnitude of variables.

It could be seen from Figure 6 that the β t content presents an increasing trend as EPT voltage increases.

While the yield strengths of the EPT8 and EPT9 samples are 726 MPa and 771 MPa, exhibiting a decreasing trend generally, which could be attributed to the decrease of α p and the increase of β t [ 11 ], the EPT8 sample possesses the lowest yield strength, which is corresponding to the highest area fraction value of β t .

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
