Excerpts

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.

The relative density results show a clear trend of increased densification with higher sintering temperatures, peaking at 1200 °C.

Passivation of 410 SS in acid nitric showed a trend in the cyclic potentiodynamic polarization curves, although it was not fully defined.

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.

Both the SBS-modified asphalt and the 70# base asphalt exhibited an increasing trend in asphaltene content during aging.

At 50 °C, it was observed that after the epoxy asphalt was left for 60 min, the crack showed a clear trend of healing compared to the initial crack.

Accordingly, the compressive strengths of the geopolymers at 7 days and 28 days showed a trend of increasing and then decreasing when CaCl 2 was added.

The results are reported in Table 3 and show an interesting trend.

The conclusions that can be drawn from this study are summarised as follows: As expected, the normal and cutting forces showed an increasing trend with the increasing scratching velocity when using the Johnson–Cook constitutive model, while the scratching speed had no influence on the simulated forces in the case of the elasto-plastic material model.

In this study, DC of SBU showed a trend similar to previous reports [ 38 ].

Currently, there is an increasing trend in using the PolyJet method to produce models for the medical industry, especially the dental industry [ 33 , 34 ], as well as injection molds and model sets for silicone molds used in short production runs [ 35 , 36 , 37 , 38 ].

With respect to global accuracy, the results suggest that the deviations in the plaster master casts generated on the basis of VPS and PE materials were, in general, small but partially significant different.

So far, the effect of thermal treatment of diatomite on the ability to dampen sound has not been described in the scientific literature, nor has the study of diatomite from the deposit presented in the article, which is quite significant due to the amount of material and its origin. 2.

Based on the data in Table 3 , a clear trend can be observed: as the step distance l increases during the deposition process with a glass pipette, and the differences between the upper and lower limits r 1 and r 2 decrease, and the average deposition speed for a 70 μm line segment significantly improves.

[ 35 ] used LN 2 to cool heated marble, observing a significant increase in porosity, while l V p , UCS, and E showed a decreasing trend, primarily due to thermal damage incurred during rapid cooling.

With increasing cooling rates, the proportion of micropores and small pores in granite gradually increases, and there is a clear trend of increasing pore size.

In recent years, the pursuit of lightweight of aerospace and aircraft components has emerged as a significant trend alongside the rapid growth of the aviation industry and additive manufacturing (AM) [ 5 ].

Furthermore, an increasing trend in the reactivity of the activated samples was detected with an increasing rotation speed or milling time.

Meanwhile, a comparison of Figure 7 a,b reveals a decreasing trend in the resonance displacement response of the specimens as the temperature increases from 50 °C to 100 °C.

The need to collect and recycle batteries varies from one country to another, but there is a definite trend towards stricter control over this aspect [ 4 ].

It can be seen that as the σ 3 increases, the failure vibration number of the specimen decreases, while the growth rate of pore water pressure accelerates, and the pore water pressure curve shows an increasing trend from slow to steep, indicating that the liquefaction resistance of the solidified specimen gradually decreases [ 42 ].

Subsequently, when the concentration increases to 1.5 mol/L, a decreasing trend is observed.

When soaked in water, secondary hydration occurred, resulting in an increasing trend of 518 phase content in MOC.
