Excerpts

The peak stress after acid and alkali corrosion shows a decreasing trend in good agreement with the results of Huang et al.

The results indicated the tensile strength and split tensile modulus of the sandstone specimens gradually decreased with the polarisation of the solution pH, and the acoustic emission signal ring number monitoring values showed an increasing trend.

Calcium formate and lithium carbonate had inhibitory effects on the fluidity of liquid B in the dosage range, and the slurry’s flowability with the increase in doping showed a decreasing trend, followed by increasing and then decreasing.

It can be seen from Figure 2 b that when the amount of calcium formate was constant, the fluidity of the liquid also first showed a trend of decreasing, then increasing and decreasing again with the increase in the amount of sodium sulfate.

With immersing, the C R value for the alloys presented a decreasing trend.

The results show that the thermal conductivity of the composites shows an increasing trend with the increase in the volume fraction of spherical or flake boron nitride, but the flake boron nitride enhances the thermal conductivity of the composites more obviously.

From Figure 10 b, it can be seen that the weight increment efficiency shows an increasing trend during the increase of S/d h from 2 to 4 and decreases when S/d h increases to 5.

In Figure 5 a, the dynamic IFT of HTLP-ME at various concentrations exhibits a decreasing trend over time until it reaches a constant value.

We observed a decreasing trend in the strain difference between the maximum and minimum values within the region of interest as the temperature increased from 0 °C to 50 °C for the Group C devices while undergoing the same 3 mm stretch.

[ 105 ] studied the mechanical properties of polymer concrete by replacing cement with fly ash and found that the addition of fly ash increased the compressive strength and elastic modulus of polymer concrete, but the splitting tensile strength and flexural strength showed a decreasing trend with the increase in the amount of fly ash added.

With a decrease in cooling rate, both EG and BG samples show an increasing trend in EXCO sensitivity.

A clear trend can be observed that the energy absorption ( E total ) increases linearly with the increase in compression displacement ( d ).

Consequently, as the number of particles increases, the computational burden becomes exceedingly significant.

As shown in Figure 2 a, with the increase in CTBN addition, the epoxy resin matrix’s K IC value showed an increasing trend.

Figure 6 b indicates that the friction coefficient exhibits an increasing trend followed by a decreasing trend with an increase in sliding velocity.

As a result, the absence of a pronounced trend during the 2-day and 4-day curing periods was observed.

However, specimens cured for 2 days and 4 days did not exhibit a clear trend in water stability coefficient with increasing XG content.

A clear trend in terms of the superplasticizer content can be observed.

The same authors also revealed a decreasing trend of CR values and, consequently, an increment of weight loss percentage, as also obtained in Figure 6 .

A slight trend to increase the content of Mg 2+ and Zn 2+ ions was observed in the sequence Gly → Ala → Val.

The layer after bending with the largest share of tensile stresses (OR) has a decreasing trend of nanohardness from the surface to deeper subsurface layers.

As the particle size of peanut shell powder decreased, the penetration, softening point, and ductility of the modified asphalt showed an increasing trend, while the dynamic viscosity gradually decreased.

The addition of peanut shell powder resulted in a decreasing trend in both R q and R max , indicating a reduction in the roughness of the asphalt microsurface and a smoother microsurface, consistent with the results from the 2D and 3D topography images.

According to the fitting results, the significance level values of all variables, P, are less than 0.001, indicating that the regression is extremely significant; the adjusted R 2 values of all variables are above 0.8, and as per general conventions, the closer the R 2 value to 1, the better the fit.

As depicted in Figure 9 b, there has been a clear trend indicating that the flexural capacity of a beam rose in tandem with the augmentation of the area of reinforcements.
