Obviously, with the external magnetic field rising from 0.1–0.5 T during hot-magnetic drawing, the M s value of samples exhibits a decreasing trend (sample a: 37.2384 emu/g; sample b: 34.6394 emu/g; sample c: 28.6675 emu/g; sample d: 24.9637 emu/g).

Similarly, the fracture model in this study also showed a trend that the fracture line became complex and rough as the impact speed increased.

However, at 7, 14, and 28 days, all the mortars with 7% of coarse silica fume followed a clear trend, i.e., the higher the limestone content, the lower the flexural strength.

p < 0.05 was adopted as significant, and p < 0.01 as highly significant. 3.

The flexural strength of each age showed a trend of first decreasing and then increasing with the increase in the modulus of water glass, and it was the minimum when the modulus was 1.4.

With the increase in solid content, the compressive strength of each age shows an increase first and then a decreasing trend.

With the increase in the modulus of water glass, the compressive strength of the material at 2 d age showed an increasing trend, and the maximum value was 15.2 MPa.

The augmentation peak intensity corresponded to m -ZrO 2 and t -ZrO 2 , and a decreasing trend is observed for β -Ca 3 (PO 4 ) 2 .

After 80 days of UV irradiation exposure, a significant decline in the macroscopic mechanical properties occurred in the longitudinal direction, with the largest decrease of 23% in longitudinal compressive strength and a decreasing trend in the transverse mechanical properties at the later stage of aging.

V-Notched Rail Shear Test Results and Discussion The in-plane shear strength/modulus showed an increasing trend at the beginning of aging as shown in Figure 18 .

When the p value is less than 0.01, the model is extremely significant.

Then, a negative trend appears due to the agglomeration problems.

With increasing temperature, the accuracy of the three models all shows a decreasing trend.

Specific Heat Capacity Heat capacity ( Figure 11 ) exhibited an increasing trend with rising temperature, as expected by the Debye model.

With the increase in calcination temperature and sintering time, the content of C 3 S increased gradually, and the content of C 2 S in each sample showed a trend of first increasing and then decreasing.

The results of the analysis of variance of the data related to fiber length are shown in Table 2 , which demonstrates that the influence of cotton varieties (V) and cotton regions (R), as well as interactions, were highly significant in this study.

The differences in results between the 25° and 30° system were small, but there was a decreasing trend.

In addition, the characteristics of B x signals, the mean value, and the peak value of the average of B x had an extremely significant linear relationship with the applied fatigue stress during the stable stage of the fatigue test, which indicates that MMMT is a feasible method for fatigue stress evaluation and even residual fatigue life estimation for weldments in service. welded joint tension-compression fatigue test metal magne

The decrease in the workability is highly significant in the lower water–cement ratio because of higher water absorption [ 44 , 50 ].

On the other hand, there was a decreasing trend of hue change with increasing cellulose content that could be observed.

The results indicated pH (7.2~8), NPK value (0.9~1.8), and C:N ratio <14, and heavy metals exhibited a decreasing trend in later stages for all sets of compost materials and showed the maturity level.

The statistical regression prediction models were established as follows. (9) M T D = 4.1531 A I a − 0.1121 T F a − 3.6846 R 2 = 0.89 (10) M P D = 6.7514 A I a + 0.4139 T F a − 6.4471 R 2 = 0.93 (11) W F C = 0.1001 A I a + 0.0453 T F a + 0.6405 R 2 = 0.69 The three regression models above were tested by the F-tests and were highly significant statistically at a significance level of 95%.

The box fractal dimension also showed a decreasing trend.

The compressive strength and tensile strength showed an increasing trend with the increase in SF.

It can be seen that the YL intensity had a great relationship with the substrate, and the intensity of YL band follows a decreasing trend: C > 2M > 4A.
