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.
The analysis reveals that with increasing spray pressure, residual tensile stresses show a decreasing trend, gradually stabilizing.
The mass percentage of fine and microscopic debris in simulated rock samples gradually decreases, while the mass percentage of medium-sized debris shows an increasing trend.
Subsequently, an increase in the amount of binder resulted in an increasing trend in electrical resistance values.
The density of the material with an equal volume share of magnetite aggregate (CM1-2 ÷ CM8-16), shows quite significant fluctuations, with a clear increase with the grain size of the aggregate.
From Figure 7 , it can be seen that the resistance and filtration velocity of the different filter materials showed an increasing trend, with a good fitting effect.
The results showed that all four new filter materials showed a trend of first increasing and then decreasing their filtration efficiency with an increase in filtration velocity.
Figure 6 shows a clear trend that the more CCSS used in a mixture, the higher its water demand.
Notably, with the increase in reaction time, the absorption peaks of each dye at 554 nm, 664 nm, 505 nm and 554 nm, respectively, show a decreasing trend.
