In terms of mechanical properties, the results are summarized in Figure 25 ; as we can see, strength (YS and UTS) showed a decreasing trend, but the EL showed a slightly increasing trend [ 40 ].

Meanwhile, the hydrogen evolution results in Figure 4 b indicate that, during the whole immersion time, the corrosion rate of the blank concentration increased continuously, while the corrosion rate showed a decreasing trend with the addition of a corrosion inhibitor.

The data reveals a clear trend in the maturation of compressive strength in the concrete, with an expectation of reaching approximately 100% of its maximum strength by 90 days.

In a similar manner, glass-ceramic samples coded as CASP exhibited a decreasing trend in hardness values as the sintering temperature increased.

Among them, FAB shows the strongest weight gain curve and still shows an increasing trend after the 35 h.

Consequently, as the measurement temperature increased, the Seebeck coefficient exhibited a decreasing trend, contrasting with the behavior observed for electrical conductivity.

Figure 9 shows the thermal conductivity of CuFeS 2 , highlighting a notable trend: as both the measurement temperature and HP temperature increased, the thermal conductivity exhibited a decrease.

Concurrently, the pile density of the mixture also shows a decreasing trend.

The significance of the regression equation can be tested by the F-test: F = ( Q x m ) / ( Q e n − m − 1 ) When the F-value ≧ Fe(m, n − m − 1), then the regression equation is significant at the significance level α, as follows: When F ≥ F 0.01 ( m , n − m − 1 ) , the regression equation is highly significant; When F 0.01 ( m , n − m − 1 ) ≥ F ≥ F 0.05 ( m , n − m − 1 ) , the regression equation is significant; When F 0.05 ( m , n − m − 1 ) ≥ F ≥ F 0.1 ( m , n − m − 1 ) , the regression equation is significant at the 0.1 level; When F < F 0.1 ( m , n − m − 1 ) , the regression equation is not significant.

The flowability of the novel superfine cement slurry with U 20 T 4.0 , U 30 T 4.0 , and U 40 T 4.0 ratios all exhibit an increasing trend followed by a decreasing trend with the increased water reducer dosage, peaking at 235 mm.

Although the initial strength of the 10% replacement sample was slightly higher than that of the general sample, the strength after 7 and 28 days demonstrated a decreasing trend.

One of the highly significant topics that has received increasing attention in recent years, driven by increasing environmental awareness, is the biodegradability of commonly used items.

Europe shows a positive trend in recycling, although disparities exist between countries.

However, in the case of LDH, it showed a decreasing trend at the fourth week and increased at the eighth week.

Meanwhile, the Poisson’s ratio shows an increasing trend.

Burnishing with n p = 3 indenter passes decreases the amount of austenite to 37 vol.%, while five-pass burnishing causes a quite significant deformation decomposition of austenite, with the formation of 80 vol.% of deformation martensite in the surface layer with a thickness of 100 μm.

With an increase in the solid solution treatment temperature, the hardness of Incoloy 825 showed a decreasing trend, while the hardness of 20CrNiMo first decreased and then increased.

The dependency of porosity on pore-former content in green bodies with various pore-former sizes does not show a clear trend with increasing pore-former size.

When comparing the slope of shrinkage with different pore formers, there is a decreasing trend, with PF20 having the highest slope of 0.2478, and PF90 having the lowest slope of 0.0138.

Corncob biochar showed a clear trend, in which the surface area increased with pyrolysis temperature and oxidation, resulting in higher adsorption capacities.

Concurrently, the diffraction peak of ettringite shows a decreasing trend with the increase in TG content.

Although the data presented in the diagram do not show a clear trend in the tensile strength as a function of the binder dosage, it is possible to discriminate between the different types of mixtures based on the average ITS levels.

In addition, the same sample shows a decreasing trend in its dielectric constant with increasing frequency.

The main conclusions are as follows: (1) Extending the aging time leads to a decreasing trend in the tensile strength of the alloy, while the electrical conductivity shows an increasing trend during the two-step aging process.

However, as the temperature increased to 378 K, the RMSD values rose to 0.871 Å for silk I and 0.843 Å for silk II, reflecting a clear trend of increasing structural deviation with temperature.
