The potential difference between the cathode area and the anode area showed a trend of first increasing and then decreasing with time, and the conclusions obtained are consistent with the study of Juxin Fang [ 27 ]. 4.

After the T4 treatment, the solid solution amount of Cu in the matrix showed a trend of first increasing and then remaining stable.

It can be seen that, in the range of this test ratio, the density of similar materials with an increase in the aggregate–binder ratio showed an increasing trend; with an increase in the calcium carbonate content, it showed an oscillating change; with an increase in the cement–gypsum ratio, it first decreased and then increased; with an increase in the moisture content, it showed the trend of firstly increasing, then decreasing, and then increasing; the changes in the moisture content and the content of calcium carbonate did not have a significant effect on the density.

It can be seen that, in the range of this test ratio, the cohesion of similar materials with an increase in the aggregate–binder ratio and calcium carbonate content showed a decreasing trend, while the cohesion with an increase in the cement–gypsum ratio showed an obvious linear increasing trend.

The cathodic zone of the member reacted the most actively, and the potential difference between the cathodic and anodic zones first showed an increasing trend and then decreased with time.

Analysis of variance (ANOVA) was adopted to analyze the sensitivities to each factor, which showed that the aggregate–binder ratio had a highly significant effect on the density of the material, the cement–gypsum ratio had a highly significant effect on the compressive and tensile strength of the material, the cement–gypsum ratio had a significant effect on the cohesion and density of the material, and the moisture content had a significant effect on the compressive strength of the material.

On the other hand, the moduli of published Bio-HEAs/MEAs with various values of δ seem not show a clear trend.

However, in Figure 1 b, there is a clear trend of a decreasing amplitude of the intensity peak with the substitution of Se and Te.

It was found that the soil infiltration rate showed a decreasing trend.

As shown in Figure 9 b, with an increase in filler content, R b showed a trend of increasing first and then decreasing; that is, there was an optimal filling ratio of 0.3 wt.% for the f-GO nanosheet in RTV.

With an increase in cycle number, the compressive indexes of the specimens showed a trend of “increases at first, and then decreases”, and the MOE dy and UCS of the specimens reached the maximum at 60 cycles.

Our computational results show a clear trend in the interpretation of the solvation ability of various solvent molecules and can be highly effective in interpreting the experimental results.

The quadratic multinomial regression model is obtained in Equation (9). (9) T m a x = 0.2632 + 0.1462 × n + 0.2765 × f z − 0.0655 × a p + 0.2819 × t + 0.0682 × n × f z − 0.1358 × n × a p − 0.0443 × n × t − 0.0528 × f z × a p − 0.0538 × f z × t − 0.2185 × a p × t + 0.01098 × n 2 + 0.1228 × f z 2 + 0.1452 × a p 2 − 0.8724 × t 2 From the table, the model F-value is 6.54 and the p -value is less than 0.001, showing that the model is highly significant.

In this study, the maximum tap density was achieved when the fraction of small particles was 40%; the tap density exhibited a decreasing trend above and below this point.

This indicates that as the curing age increases, the chemical reactions of each component of the curing agent become more thorough, and the brittleness of solidified soil shows an increasing trend.

However, as the concentration of K 2 ZrF 6 increased further, the process voltage exhibited a decreasing trend.

As shown in Figure 12 , under the influence of the interweaving of ameliorants and structural ameliorants, soil pore distribution characteristics showed an increasing trend followed by a decreasing trend.

Then, there was a decreasing trend in maximum amplitudes followed by an increasing trend up to the second peak, defined as stage II.

The addition of TiO 2 to PLA caused a statistically significant decrease in the contact angle values of both the composite and the coated specimen, and a decreasing trend in the values of the composite to the coated sample.

Both the UTS and EL of the alloy showed a trend of first increasing and then decreasing.

The WVTR analyzed using the water vapor permeation analyzer exhibited a decreasing trend from 0.3040 to 0.1802, 0.1088, and 0.0972 g m −2 day −1 when the duty cycle for fabricating AlON films increased from 5% to 10%, 15%, and 20%.

The admixture of casein influenced the properties of the mortar, but not in all cases, and it was possible to determine a clear trend related to the variable amount of casein.

Figure 8 demonstrates that, as the aging duration increased, the antioxidants within the B-FWJ, which had undergone hydrothermal aging at various temperatures, underwent gradual consumption, resulting in a decreasing trend in their OIT values.

Before the boundary, the diameter and length of the fibers in the B-FWJ did not change significantly, but the number of fibers in the B-FWJ showed an increasing trend.

Differences were considered statistically highly significant at p < 0.01. 3.
