Subsequently, an increase in the amount of binder resulted in an increasing trend in electrical resistance values.

The density of the material with an equal volume share of magnetite aggregate (CM1-2 ÷ CM8-16), shows quite significant fluctuations, with a clear increase with the grain size of the aggregate.

From Figure 7 , it can be seen that the resistance and filtration velocity of the different filter materials showed an increasing trend, with a good fitting effect.

The results showed that all four new filter materials showed a trend of first increasing and then decreasing their filtration efficiency with an increase in filtration velocity.

Figure 6 shows a clear trend that the more CCSS used in a mixture, the higher its water demand.

Notably, with the increase in reaction time, the absorption peaks of each dye at 554 nm, 664 nm, 505 nm and 554 nm, respectively, show a decreasing trend.

Therefore, compared to the extension line of the S–N curve for the surface crack initiation, the fatigue life of the internal crack initiation has shown an increasing trend ( Figure 3 ).

As depicted in Figure 5 , when the replacement rate of recycled coarse aggregates reaches 50%, the compressive strength of recycled concrete exhibits an increasing trend alongside the volumetric dosage of steel fibers.

The significant findings from this research include the following: The hysteretic response of the masonry panel exhibited approximately symmetric loops in push-and-pull load cycles with an increasing trend of lateral strength except in the last push load, in which the load carrying capacity reached maximum value of 114.3 kN and then decreased to 109.1 kN, corresponding to 1.73% and 2.02% drift index, respectively.

Additionally, the flexural strength of the GMPF samples with a 3.0 vol% polypropylene fiber dosage shows a decreasing trend, with a 7.1% decrease compared to the preceding group.

Furthermore, polypropylene fibers significantly improved the matrix’s flexural toughness, which showed an increasing trend with higher fiber content.

As the Al content increases from 6 at.% to 14 at.%, the combustion enthalpy of the alloys has a slightly increasing trend ( Figure 7 a), from 10.826 KJ/g at x = 0 at.% to 11.749 KJ/g at x = 8 at.%.

Upon cell activation, the capacity of the electrodes shows an increasing trend, which was followed by a gradual stabilization.

Overall, as the temperature increased, the sample exhibited a significant trend of radial shrinkage.

The F -value of 66.94 and the adjusted regression coefficient above 99% indicate that the model equation is highly significant.

Fineness, measured via an air permeability apparatus, was approximately 3600–4000 cm 2 /g and showed a trend of increasing as the limestone content increased.

By considering these results, an unexpected trend can be noticed: with the increase in elongation, the breaking angle also increases.

The influence of the STR is more pronounced for Mg and Cu alloys than for Zn alloys, while the fraction of the eutectic phase shows an increasing trend with increasing Zn, Mg, and Cu content.

As shown in Figure 4 g,h, water content at both loading current densities has a decreasing trend with an increasing stoichiometric ratio, and a stoichiometric ratio of 100 generates more water content than a stoichiometric ratio of 400.

Keeping the mass fraction of RM constant, the value of UCS showed an overall trend of first increasing and then decreasing with the increasing modulus of alkali activator.

It can be seen that the solid solubility of Nb in austenite showed a trend of first decreasing and then increasing with the increase of carbon content, which was similar to the trend calculated by Ohtani’s equation, as shown in Figure 2 .

While the left-edge and right-edge flash areas increased with deposit height, as a percentage of the total area, they did not follow an obvious trend with increasing deposit height.

The compressive strength showed a decreasing trend, and as the dosage of waste rock wool increased, the proportion of cement decreased, the dosage of cement hydration products decreased, and the internal structure of the mortar was loosened.

NaNO 3 related with the oxidation of water, which creates surface functional groups on the carbon electrode, are quite significant, as is the reversible hydrogen adsorption and desorption reactions at the negative electrode due to the electrochemical reduction in water.

With increasing CaO, the conductivity of the alloy shows an increasing trend, and it is lower than that of GB/T26867-2011 [ 23 ] at 10%, 15%, and 20%.
