Excerpts

Figure 12 illustrates that the strain values at different strain gauge positions, as local variables, are quite different and do not exhibit a clear trend.

A clear trend was observed: higher bulk density tends to increase water vapor transport resistance.

As the sintering temperature increased, porosity showed a decreasing trend while compressive strength progressively rises.

In contrast, porosity exhibited an increasing trend as the content of the pore-forming agent rises.

Therefore, the MB value of the reclaimed powder did not show a significant trend of influence on the compressive strength overall. 3.1.3.

As the Ca 0.5 Sr 0.5 TiO 3 content increased, the average grain size of the ceramics exhibited a decreasing trend and the relative density declined, attributed to the higher sintering temperature of Ca 0.5 Sr 0.5 TiO 3 , which impeded the grain growth and densification of ZnNb 2 O 6 -based ceramics.

A clear trend was observed, where the failure strain decreases with increasing grain size.

Acid etching duration exhibits a negative trend: longer erosion periods yield lower predicted uniaxial compressive strength, with this effect being marginally more pronounced in GA-XGBoost.

It can be observed that, compared with the as-received samples [ 37 ], the mechanical properties of the hydrogen charging samples all show a decreasing trend with the increase in charging times and current density.

(2) The increment in Ta content led to an increasing trend followed by a decrease in the activation energy E g , E x , and E p of the alloy systems.

As the AFR increases, the W content in the binder phase shows a decreasing trend.

Therefore, the results are as expected as a clear trend can be seen with a correlation coefficient of −0.79.

It can be seen in Figure 7 c that the aromatic lamella spacing (d 002 ) of coal samples showed a decreasing trend with an increase in temperature.

It is also noted from Figure 9 that not only the maximum load but also the displacement corresponding to this maximum load demonstrates an increasing trend with extended solution treatment time.

Although higher volumetric energy generally leads to deeper melt pools [ 33 , 34 ], an interesting trend was observed: increasing beam diameter also correlated with deeper pools, even when volumetric energy density decreased.

As initial results ( Figure 10 and Figure 11 ), we can conclude that there is a clear trend: the greater the texture depth, the lower the CPX (except in the AC16 reference), and that most SMA fluctuates ±2 dB in 24 months, while AC16 increases by more than 2 dB. 6.

It can be observed from Figure 10 b that at an SMAF content of 0.3 vol.%, the ultimate tensile stress of SMAF-ECC specimens shows a decreasing trend with the increase in SMAF diameter.

As shown in Figure 8 a,b, both V oc and J sc exhibit an increasing trend with the widening of the gap width.

Meanwhile, according to Figure 8 c, FF shows a decreasing trend as the gap width increases.

Notably, as the Si/Al ratio increased from 1.0 to 2.0, the ratio of (Q 3 + Q 4 )/(Q 1 + Q 2 ) exhibited a decreasing trend.

The resistance will exhibit an increasing trend from this stage, attributed to the formation of CIC products such as Fe(OH) 3 and Fe 2 O 3 ·nH 2 O [ 60 , 61 ].

An increase in tempering temperature will accelerate the climb and submergence of dislocations, resulting in a decreasing trend in dislocation density.

As can be seen in Figure 10 , the chromatic aberration shows an increasing trend as the aging time increases.

In Figure 9 a, it can be seen that the brightness shows a decreasing trend as the aging time increases, but the attenuation is relatively small.

As shown in Figure 3 b and Figure 4 b, at a W/B of 0.250, the yield stress and plastic viscosity of all ECC pastes generally show a decreasing trend as the SP dosage increases.
