Fluence (power*number of passages/scanning speed) positively influences outputs and presents a positive trend.

It can be observed that at the same temperature, the slope of the medium and low power density is larger, which has an extremely significant effect on the welding strength.

From Table 4 , it can be observed that the F-value of the viscosity response model is 92.76, with p < 0.0001, indicating a highly significant impact of the independent variables on viscosity.

A notable trend emerged: a decrease in the w/b led to an increase in the percentage of harmless and less harmful pores while simultaneously decreasing the percentages of harmful and multi-harmful pores.

The Q 2 and Q 4 unit fractions generally presented declining trends, with the concentration of NaOH solution rising from 5 M to 15 M, whereas an increasing trend was observed for the Q 3 unit.

The results show that there is an increasing trend of displacement versus temperature and the fork is due to the slow shrinkage and creep effect.

However, when the specimen size increases, U , U d , and U e all show a decreasing trend, and the amplitude of this decreasing trend becomes more obvious with the increase in strain rate.

Moreover, as the specimen increases and the strain rate decreases, U e / U shows a gradually decreasing trend while U d / U shows an increasing trend, indicating that the proportion of elastic strain energy used to release decreases at this time, and the degree of brittle failure of the specimen also decreases.

From 120 ms to 240 ms, when the temperature of the electropulsing treatment is relatively low, the elongation of the material shows an increasing trend, while the tensile strength gradually decreases.

As loading progresses and the deformations increase, the viscous damping coefficient shows a decreasing trend, resulting in an overall reduction in energy dissipation capacity.

Nonetheless, with an excessive concentration of diatomite (wt.% > 1.1%), the yield stress and plastic viscosity of the geopolymer coatings exhibit a decreasing trend.

At the same time, with the increase in the replacement rate of recycled aggregate, the strain size of the specimen when it reached the peak point was also increasing, and the curve as a whole showed a trend of right–downward deviation.

As the dosage of PS beads increased, the compressive strength showed a trend of initially increasing and then decreasing.

The impact of electrode polarization, which might be significant at low frequencies, can be ignored in this frequency range [ 81 ].

Contrary to the trend of ultimate tensile strength, the ultimate tensile strain showed a trend of decreasing and then increasing; however, the strain of the specimens in the 5% Na 2 SO 4 and 5% Na 2 SO 4 —3% NaCl solutions under the same tensile strength was lower than that of the aqueous solution specimens, which indicates that the erosion of salt particles caused the matrix to become brittle, thus causing the strain to decrease. 3.1.3.

The SIMS result for Sample H reveals a notable trend that the H concentration exhibits higher levels within the depth range of 50~150 nm compared to a depth of 400~450 nm.

The results in Figure 4 , Figure 5 and Figure 6 and Table 1 demonstrate the dimensions of the formed layer, which show an increasing trend due to the accelerated kinetics of the oxidation reaction as the temperature increases.

These mortar samples showed an increasing trend of shrinkage over time.

Generally, compressive strength and elastic modulus followed a decreasing trend with increasing porosity.

The conductivity of the films exhibited an increasing trend with increasing temperature, reaching a peak value of 1.12 S/cm at 80 °C.

As the NaAlH 4 content increased, a notable trend was observed in the curve depicting the ratio of hydrogen release at the temperature peak to the increase in temperature.

As the three parameters increased, the cross-sectional area of the fiber bundles generally showed a trend of first increasing and then decreasing.

This demonstrated a clear trend showing that the HE susceptibility increased with longer aging periods and larger sizes of k-carbides, as evidenced by the significant reduction in elongation. 3.3.

In this process, the dominant effect of air content on thermal conductivity results in an increasing trend with the rising water–cement ratio.

As the water content increases, the amount of moisture that can be lost during the same preservation process also rises, causing a decreasing trend in the wet density of the material with the increasing water–cement ratio.
