Excerpts

The five groups of different lengths have a clear trend; that was, the energy absorbed by the lattice energy decreases with the increase in length.

It was noted that the physical, mechanical and chloride penetration resistances have generally displayed a decreasing trend, with an increase in the manmade plastic aggregate replacement fractions as compared with reference lightweight concrete.

fiber density did not display a clear trend.

The hardness shows a decreasing trend as thickness increases.

In Figure 8 b, the flux density increases and then decreases with the increase in stress at a certain temperature, and the flux density is maximum at about 35 Mpa; the flux density shows a decreasing trend with the increase in temperature at a certain stress.

The experimental results are shown in Figure 7 , where it can be observed that the saturation flux density of the grain-oriented silicon steel increases with increasing frequency and the losses show an increasing trend, but the growth is slower at lower frequencies and increases faster at higher frequencies, which is also in accordance with Equation (4) [ 26 ].

It should be noted that this minimum illustrates a non-symmetrical profile, demonstrating an increasing trend after 1770 min and culminating in a local maximum in Stage V.

Nevertheless, with the increase in carbon nanofiber loading, an increasing trend of shape parameters and, therefore, a decline in the degree of scattering in the strength was monitored for carbon nanofiber implanted GE composites [ 39 ].

With the increase in content, the compressive strength of the cement paste showed a trend of increasing and then decreasing.

After starting lighting, the rate of temperature increases at all points, maintaining a decreasing trend until the temperature reached its peak.

A noticeable increase in the ultimate deflection, i.e., the deflection of the post-peak softening branch at which the specimen attains 85% of its load capacity, was only found when ten vertical reinforcing bars were put in place (21% and 25% for pitch reduction from 250 mm up to 150 mm and 50 mm, respectively), while a clear trend was not revealed for six and eight longitudinal rebars [ 51 ].

With the increase in confining pressure, all stress–strain curves also show an increasing trend.

Figure 6 shows the flexural strength of MKPC at different ages, when M:P is the same, the flexural strength shows a decreasing trend with the increase of FA doping.

Under the same age, the flexural strength of MKPC mortar shows an increasing trend with the increase of silica fume admixture.

It can be found that in conditions 2 and 3, when there is periodic wear on one side of the wheel and the rail, the real part of the eigenvalue of the system shows an increasing trend relating to the condition 1.

The temperature dependence of the Seebeck coefficient shows an increasing trend in performance as the applied temperature is increased, as seen in Figure 7 b.

It can be seen from Figure 4 that under various temperature conditions, the instantaneous friction coefficient of intermittent braking generally fluctuated greatly, but during 10 min of operation, the instantaneous friction coefficient under various temperatures showed a trend of first increasing and then decreasing.

The decrease in ambient temperature first caused an increasing and then a decreasing trend of wear rate of the brake disc and reached the maximum value (84.5 μg/r) at 0 °C.

As the heat-treatment time further increases, the microhardness of alloys shows a decreasing trend, where Alloy E only has half the microhardness of Alloy A. 3.3.

The tensile test displayed that the tensile strength of the composites presented an increasing trend with the increasing (Ti, Nb)B content followed by a decreasing trend.

Both dynamic strength and deformation modulus showed a decreasing trend with the increasing defect strength.

Figure 8 d, which summarizes the volume fractions of constituent phases in these alloys, expresses an overall trend that the volume fractions of the BCC phase and D8 8 phase increase with increasing Ti concentration whereas that of the A15 phase has the opposite tendency.

In all of them, a clear trend of a greater impact on hydrochar is shown, as well as a consequent lower impact of biosorbent.

The strength of the mortars exposed to chloride-sulfate coupling showed a decreasing trend for all groups, and the phenomenon was exacerbated by the further coupling of carbonation, where the most obvious strength loss was in Specimen C without admixture, whose strength loss was 13.4% under the three-factor coupling, indicating that the mineral admixture, in particular the metakaolin, could improve its resistance to erosion to some extent.

After 40 F–T cycles of the sample, the total number of pores increased from 20,832 to 24,160 by about 15.98%, and the number of pores in all ranges showed an increasing trend.
