Excerpts

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.

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%.

An increase in sintering temperature from 800 to 1200 °C led to an increasing trend in hardness, primarily due to the higher relative density and formation of α’ phase.

At 650 °C ( Figure 11 a), it is evident that all five materials exhibit an increasing trend in their kinetics.

An increasing trend in tensile strength was observed with increased bulk density (σ t = 0.0027697·ρ − 4.5892, r = 0.60).

(2) Effect of CAS on CRCA apparent density As shown in Figure 4 , under completely dry conditions, Δ ρ a showed an increasing trend and then decreased with increasing CAS, and the RCAs with a CAS of 10–20 mm and an OCS of C40 had the largest Δ ρ a after carbonation, 3.95%, which was the most significant improvement.

The water absorption of CRCAs with an OCS of C30 decreased with the increase in CAS, while the water absorption of CRCAs with OCSs of C40 and C50 showed a decreasing trend and then increased with the increase in CAS.

The Δ W a of CRCAs with a CAS of 20–25 mm showed a trend to decrease and then increase with the increase in OCS, and the CRCA with an OCS of C50 had the largest Δ W a , 23.38%.

With the increase in the proportion of powder addition, the wear volume of the coating shows a decreasing trend, and the wear resistance of the surface coating is improving.

Meanwhile, the MAGBs show an increasing trend, which indicates that CDRX behavior occurs during hot deformation.

Across all batch systems where the Ca(OH) 2 concentration was varied, an overall trend was observed concerning the influence of pH on NH 4 + and NO 3 − concentrations at the end of the reaction.

After that, a slight trend towards a higher rebound elasticity can be observed over the storage period. 3.4.

Compared to alloy I, the yield strength of alloy II with an LPSO phase showed an increasing trend at 25 °C~200 °C and then decreased when the temperature reached around 250 °C.

Due to the migration of substances from coffee and tea to the surface of the samples, as well as the natural heterogeneity of coffee and tea additives, the measurement results did not show a clear trend.

An examination of the natural frequencies indicates that as the wall thickness increases, there is a decreasing trend in natural frequency, with a slight mutation observed at the ratio of 0.25.

With the increase in MgO and resin content, the initial permeability, maximum permeability, and saturation magnetic induction of the material showed a decreasing trend.

14 decreased with increasing pore diameter, but their porosity does not show a clear trend.

However, when the mass ratio of BC to Cu/Cu 2 O increases to 0.3, the removal rate begins to show a decreasing trend.

However, comparing the CTE behavior of all selected conditions, despite P 1, as displayed in Figure 2 , the partially significant differences in the grain sizes do not appear to have any pronounced influence on the CTE behavior.
