Excerpts

The K–S special interphase boundaries showed a trend of increasing first and then decreasing with increasing heat input, which was like the change rule of the substructure grains and deformed grain ratio, but was opposite to the change rule of the recrystallized grain ratio.

Their research group noticed a decreasing trend in killing efficacy over the days of the study, under exposure to both UV and visible light.

However, a pronounced trend was observed where the strength of the specimens significantly dropped with prolonged corrosion time.

With respect to the amount of porosity left in the sintered alloys, an increasing trend is found.

A notable trend was that the surface pores and voids closely follow the morphology of the compacted turnings, with less apparent pores and voids in sintered materials.

In the figure, from stage I to stage III, the permeability shows a decreasing trend, and the overall decrease in permeability in this stage is small; in stages IV and V, the rock volume changes from compression to expansion, and the rock volume strain continues expand, the permeability of rock first increases slowly, and then increases sharply with the drop of stress, the permeability of rock reaches a maximum value, and then decreases rapidly and tends to be stable as the fractures are compacted (stable increase, steady decrease, and approximate level).

It can be observed in Figure 14 b that with the increase in density and decrease in porosity, the peak load will show an increasing trend.

Therefore, the use of environmentally friendly nanomaterials for micro spectrometers is an important trend.

In the future, there may be a strong trend for nanomaterials to replace traditional materials in the field of micro spectrometers.

When the corrosion inhibitor concentration was increased to 100 ppm, the self-corrosion current density I coor reached a minimum of 2.207 × 10 −5 A/cm 2 , the charge transfer resistance reached a maximum of 932.5 Ω·cm 2 , and the corrosion inhibition efficiency reached a maximum of 95.2%, and the corrosion inhibition efficiency showed a trend of increasing and then decreasing with increasing concentration.

Between 9–10 ms, as the AC current approaches zero crossing, the anode contact temperature also exhibits a decreasing trend, ultimately reaching around 1260 K.

Then, as the heating temperature increased, the contact angle between the flux and the alumina showed a trend of gradually decreasing, and the flux also gradually spread out on the surface of the alumina in the image, which also indicated that there was a good wettability between flux #10 and alumina.

As for dimensional accuracy ( Δh ), a highly significant interaction was found between current density and EP time.

Moreover, the As15-6 tool wear curve for the machining of C45 steel showed a decreasing trend of wear with time, unlike other materials.

A clear trend of absolute Seebeck coefficient values decreasing, with increasing the Cu doping amount, at low temperatures, can be seen as is expected upon increasing the charge carriers upon the electron donor Cu doping.

It was observed that the mixtures with cenosphere aggregate replacement exhibited an increasing trend in specific strength as the cenosphere aggregate replacement content increased.

For the vitroceramics with x = 30 mol% NaH 2 PO 4, a decreasing trend in the intensity of the IR bands between 530 and 1200 cm −1 was observed, but its width was increased.

With the increase in (Cu, Ni)-ZnO additions, the thickness in nanocomposite coatings showed a trend of increasing first and then decreasing.

The DMA results for all tested samples show a clear trend: for materials with good energy absorption capacity, the storage modulus increases with frequency.

Moreover, analyzing the axial shrinkage recorded for clay compositions PV1–PV4 (compositions that do not contain dextrin), a decreasing trend of this indicator is observed as the amount of lime increases.

The peak strain and elastic modulus initially demonstrated an increasing trend, followed by a subsequent decline, with an increase in initial deviatoric stress.

As mentioned at the beginning of this section, the influence of the CE2 dopant on the behavior of pure 5CB at lower temperatures (i.e., below the clearing point) was fairly significant.

As represented in Figure 14 , when the wall angle increases from 25 degrees to 35 degrees, the principal stresses (the tensile stress and the compressive stress) of the perforated titanium sheet showed an increasing trend.

The foaming pressure of polyurethane systems with different PBA components showed a consistent, regular change, and the foaming pressure showed a decreasing trend with the increasing addition of the PBA.

On the other hand, balls of softer materials showed a clear trend to embed the abrasive particles on their surface.
