A decreasing trend of peak current density was observed at smaller CaO content concentrations, attaining a minimum value for the sample with 12 mol%.

At higher dopant levels, an increasing trend can be observed to 50 mol% CaO.

And the lateral displacement and acceleration responses show a decreasing trend with the increase in the track beam height. 4.2.2.

Effect of Dilution Ratio From Figure 10 a, it can be seen that the 28-day compressive strength of MSWIBA foamed concrete showed a decreasing trend as the foaming agent dilution ratio increased.

Effect of NaOH Concentration and Solid-to-Liquid Ratio As shown in Figure 4 a, the SiO 2 extraction ratio exhibited an increasing trend with the rise in the NaOH concentration.

The results also reveal that both before and after the thermal exposure, the Ti65 alloy contains high-density and uniformly distributed spherical nanoscale α 2 phases, and the size of the α 2 phases remains initially unchanged and slightly increases later as the T e increases, while the content shows an increasing trend followed by a decrease.

The results indicate that as the thermal exposure temperature increases, the strength of Ti65 alloy initially increases and then decreases, while ductility exhibits a decreasing trend.

p -values of responses 1 to 6 were 0.028, 0.01, 0.003, 0.023, 0.002, and 0.026 are less than 0.05, indicating that the model is highly significant [ 86 ].

The cumulative pore volume curves did not exhibit a clear trend.

It is found that along the length direction, the bainite and martensite structures decrease from the center to the edge region, while the ferrite structure shows an increasing trend.

This leads to a decreasing trend in deformation along the length of the front axle from the center to the edge.

However, the exposed area of the naked alloy exhibited a decreasing trend as the contact time increased.

In comparison with Figure 4 a, a similar phenomenon is observed in Figure 4 b; however, the separating area exhibits an increasing trend.

As shown in Figure 4 , after 540 cycles of rapid temperature change, the shear strength of the chip–substrate joint showed a decreasing trend.

Therefore, the alkali-activated cementitious system is highly significant for cement reduction and industrial solid waste utilization in future applications [ 24 , 25 ].

Tensile type shows a decreasing trend, and the variation range is “9.24% > 8.84% > 5.89%”.

The iron powder content had a highly significant effect on σ c , σ t , τ f and c , and it had a significant effect on ν and φ .

For the AACF condition, the dimensionless number initially showed an increasing trend, then followed by a decreasing trend.

They found that the friction coefficient exhibited a decreasing trend as the sliding velocity and load increased.

It can be observed that the microhardness value exhibits an increasing trend from the substrate to the heat-affected zone and then to the coating.

Lee and Kim [ 15 ] obtained a Lorenz number of 1.54 × 10 −8 V 2 K −2 at 323 K for Cu 3 SbSe 3.2 S 0.8 , noting a decreasing trend in the Lorenz number with increasing S content.

The pore size distribution curves decrease significantly in the main peak signal, and the signal of the second peak shows an increasing trend.

(5) The number of force chains shows a decreasing trend after the cracks begin to grow.

As shown in Figure 3 b, compared with the blank group, after adding 5~15% fly ash, the strength growth rate of the cementitious materials at each age also showed a trend of first increasing and then decreasing.

Student’s t -tests yielded highly significant p -values (<0.001) for both the pellet and supernatant coefficients, falling within narrow confidence intervals (see Table 3 ).
