At the same time, it shows an increasing trend in the horizontal direction due to rGO forming a better “heat transfer path” through the interconnection structure of the PI skeleton.

A notable trend emerged: as both the discharge energy and the GNP content increased, the surface roughness escalated.

On the other hand, the surface microcrack density of Ti6Al4V exhibits a decreasing trend with an increase in discharge capacitance.

However, a linear and highly significant increase in Cd tot content (r = 0.887 **) was observed only in series 1 (with BA alone), in which the highest BA dose (90 g pot −1 ) had a statistically significant impact on the Cd tot content.

In Figure 8 c, it can be seen that as the load cycle level increases, the damping ratio as a whole shows a pattern of gradually decreasing while having an increasing trend at a later stage.

Meanwhile, there was a slight trend of increased weight loss of steel sheets in the blank medium, mainly due to electrochemical corrosion.

Under the conditions of a 4.5% and 5.25% duty cycle, the target peak current shows a decreasing trend.

When the sodium silicate content was below 25%, the compressive strength exhibited an increasing trend with higher silicate levels.

The results highlight that the crack initiation strength, damage strength, peak strength, and elasticity modulus of Jinping marble exhibit an increasing trend with an increase in intermediate principal stress, while the peak strain initially increases and subsequently decreases.

The tensile strength of the specimens subjected to one, three, and seven dry–wet cycles shows a decreasing trend with the increase in curing age.

As depicted in Figure 7 , with an increase in the slurry c/t ratio and mass concentration, the slump and bleeding rate of the filling slurry showed a decreasing trend.

The UCS of the CCPB showed an increasing trend with the rise in curing age, mass concentration, and the c/t ratio.

Recently, there has been an increasing trend, especially in the automotive sector, towards the production of cylindrical blocks to achieve the high performance of diesel engines by improving their wear and corrosion properties [ 34 ].

However, following the degradation of the cement matrix, a notable trend is observed during the failure stage (referred to as the C-stage); the reduction in the elastic modulus due to environmental temperature fluctuations has a marked impact on the compressive strength of the sample.

Due to the inherent dispersion property of the material, both ε′ and ε′′ showed a decreasing trend with increasing frequency when subjected to a heat treatment temperature of 800 °C.

Both the storage modulus and loss modulus exhibited a decreasing trend with rising temperatures and increasing DMSO 2 concentrations in the PCL matrix.

Generally, the strut diameter showed a trend of being thick with the increase in printing temperature, pressure, and DMSO 2 concentration.

Conversely, the volume expansion rate of the RM–CaO stabilized soil showed an increasing trend with the cycle number.

The UCS of the stabilized soil showed a decreasing trend as the cycle number increased.

With the decrease in RM content, the UCS showed a trend of increasing and then decreasing, and the maximum 7-day UCS was obtained when the RM content was 30%, while the maximum 14-day and 28-day UCS were obtained when the RM content was 20%.

(4) The cryogenic impact toughness of the medium-carbon spring steel shows an increasing trend with an increasing nickel content due to the refinement of the sub-microstructure of martensite (including packet and block) and the increase in the proportion of HAGBs, which shifts the brittle temperature zone to lower temperatures.

Moreover, as the nickel content increased from 0 wt.% to 1 wt.%, the M s temperature reduced from 345 °C to 318 °C, aligning well with the empirical calculation formula included in the relevant literature [ 19 ]. (1) M s = 492 − 125 x C(wt.%) − 65.5 x Mn(wt.%) − 10 x Cr(wt.%) − 29 x Ni(wt.%), °C Nickel can enlarge the γ phase region in the Fe-C phase diagram, and the Ac 3 temperatures of the tested steel exhibited a decreasing trend with an increasing nickel content, which is consistent with the related literature [ 16 , 20 ].

As shown in Figure 21 , the UCS exhibited an increasing trend with incremental additions of cement and SDA up to optimum amendment dosages of 6% by dry weight.

The liquid limit in Figure 11 shows a decreasing trend with increasing cement and sawdust ash (SDA) percentages in all mix combinations.

It revealed a decreasing trend in ultrasound velocity with an increase in times of temperature differential cycling, showing a strong linear relationship between the ultrasound velocity loss and strength loss, confirming the correlation between the degree of concrete strength degradation and internal damage.
