[ 71 ] measured fluoride release across various combinations of SrO and SrF 2 and found a clear trend: groups with 1.5% SrF 2 and 1% SrO showed the highest cumulative fluoride values (2.61 mequiv/g).

The relative ultimate bond strength shows an increasing trend as the relative anchorage length, and there is a significant linear relationship between them.

With the increase in anchorage length, the bond strength showed a trend of increasing first and then decreasing.

For instance, with 8 mm bolts, the enhancement dropped from 295% at 1 d to 47% at 4 d, revealing a clear trend of reduced marginal benefit with increasing clearance; As the edge distance increased, the dominant failure mode gradually shifted from shear failure to local extrusion failure.

The analysis reveals a clear trend toward reducing clinker content by incorporating supplementary cementitious materials (SCMs) such as fly ash, ground granulated blast furnace slag, natural pozzolans, and limestone.

A notable trend is the use of modern panoramic four-pane inserts, which enhance chimney system efficiency and improve thermal insulation.

The FFT patterns in Figure 7 F,H indicate that there may be significant deviations from equilibrium interplanar distances typical of BCC titanium crystals.

The research results show that along the direction of the armature launch, the rail surface wear transitions from mechanical wear to electrical wear, the fluctuation range of the 2D profile becomes smoother, and the roughness of the rail surface shows a decreasing trend.

The friction curve shows an increasing trend in the first 15 min and then remains stable.

Across all conditions, the Tsai–Wu strength failure values for the CFRP, G/C/G, C/G/C, and GFRP stacking configurations showed an increasing trend with a higher GFRP content, indicating that introducing GFRP led to a deterioration in structural performance.

Electrical characterization showed that the integration of PPy imparted conductivity to the hydrogels, with a clear trend of increasing conductivity with increasing PPy content ( Figure 9 ).

A clear trend of the median CoF value for the considered cases can also be observed, which can be described by a rational function.

As the oxygen content increases, the peak intensity shows an increasing trend, with the potential gradually shifting towards the positive direction.

Conversely, the retarding effect of XANa (PX) shows a decreasing trend, and at 0.15%, it demonstrates a pro-setting effect, reducing the initial setting time by around 79%.

An increasing trend in thermal conductivity can be observed as the percentage of tailings rises, progressing from approximately 0.32 W/m·K in the control sample to 0.52 W/m·K in the 50% replacement sample.

However, strong anisotropy may be significant in the case of material flow in the deformation zone.

The elastic modulus and peak stress of the Al/Ti bimetal exhibited a decreasing trend with increasing temperature, which is consistent with tensile experimental results.

A clear trend is observed: with the increase in the amount of PX200, the burning time of the material is significantly extended, which may indicate an improvement in fire resistance.

Under point contact mode, the bending fretting fatigue life of 7075 aluminum alloy first decreases and then increases with the increase in bending fatigue load, and finally shows a decreasing trend [ 16 ].

In Figure 14 , it can be observed that for specimens treated at both temperature levels, the hardness values exhibit a decreasing trend as the depth from the surface into the substrate increases, presenting a typical gradient distribution.

Similarly, the variation range of the ratio of long to short axes of voids was between 2.02 and 2.15 with the increase in porosity, showing an increasing trend but with overall little change, indicating that the internal void shape characteristics of the PAC mixture were predominantly elongated and narrow. 3.1.2.

Whether strongly or slightly significant, the performance level can be assumed to be related to the elemental composition of raw soils, a siliceous soil yielding strong benefits, while a calcareous one results in modest benefits.

The q-values do not show a clear trend following either replacement percentage or the effect of prior carbonation.

The hardness values exhibited an increasing trend according to increasing milling time.

Figure 5 illustrates an increasing trend in Ca 5 (SiO 4 ) 2 (OH) 2 contents as a function of loaded wollastonite.
