From L1 to L7, the tensile strength and modulus of elasticity showed an overall trend of steady decrease ( Figure 6 d).

The bending strength and modulus of elasticity both showed a decreasing trend from L1 to L7 on these two bending directions ( Figure 5 e,f).

In the figure, the C–C/C=C and C–H/C–N stretching modes due to the pyrrole ring in the range of 1319–1594 cm −1 show an increasing trend in their relative intensity in the Ag NW@PPy.

With the increase in BWR content, the S max , S mean , and S total values of bee-like structures of aged asphalt showed a trend of increasing first and then decreasing, and the N value showed a trend of decreasing first and then increasing, indicating that BWR may affect the formation and disaggregation of bee-like structures.

Conversely, at a constant strain rate, the grain size shows an increasing trend with rising deformation temperatures.

With a constant deformation temperature, there is a decreasing trend in grain size as the strain rate increases.

It can be seen from the figure that the compressive strength of each group of concrete test blocks shows an increasing trend with age, but the increasing amplitude is different.

On this basis, with the whisker content increasing from 0% to 0.5%, the proportion of harmless holes in concrete showed a trend of first increasing and then decreasing, while the proportion of multi-damaged holes showed a trend of first decreasing and then increasing, and the proportion of harmless holes was the highest when the whisker content was 0.4% (HF4).

The only exception is represented by the epoxy composite containing the highest boric acid content; The results of mechanical tests in compression mode do not indicate a clear trend of the influence of boric acid content on the mechanical characteristics of the tested epoxy composites.

found nanoscale grain size in the [(Ba 0.85 Ca 0.15 ) 0.995 Nd 0.005 ](Ti 0.9 Hf 0.1 )O 3 ceramics prepared via hydrothermal method exhibited an increasing trend with the increase in sintering temperature and holding time, which significantly affected the dielectric constant and T C temperature [ 22 ].

A comparison between Figure 7 a and the subsequent Figure 7 b–d reveals a clear trend: as batteries experience micro-overcharge cycling, the number of cracks (highlighted within blue circles) on the cathode material surface proliferates [ 28 ].

As the temperature increased, the residual compressive strength and elastic modulus of concrete generally showed a decreasing trend.

As can be seen in Figure 13 and Figure 14 , this study of the mechanical properties of aged Sikadur (up to 163 days) and Loctite (up to 231 days) shows a clear trend towards a progressive decrease in ultimate tensile strength (UTS) with the exposure time.

As depicted in Figure 8 a, there is a clear trend of the increased adsorption capacity of ARPA with rising temperatures for both dyes, which is indicative of an endothermic adsorption process.

With the increase in temperature and decrease in strain rate, the peak stress shows a decreasing trend.

Moreover, with an increase in CN content, the compressive strength of the cement paste shows an initial increase followed by a decreasing trend.

With the increase in sintering temperature and clay content, the bulk density shows an increasing trend.

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.
