“a decreasing trend”

[ 32 ], who found that straw returning increased the activities of soil urease, phosphatase, and invertase, with their activities in the 0–10 cm soil layer increasing by 15.1%, 11.0%, and 88.4%, respectively, and soil enzyme activities showing a decreasing trend with the increase in soil depth.

Overall, both tea polyphenol and catechin contents exhibited a decreasing trend from summer to autumn and further to spring( Figure 1 ). 2.2.

Notably, the content of D-myo-inositol in CT2 significantly increased, while the contents of another five DIMs showed a decreasing trend between the CT1 and CT2 groups. 2.9.

The major conclusions are drawn as follows: (1) As the temperature rises (25–600 °C), the mass of granite exhibits a decreasing trend, while its volume and porosity increase nonlinearly.

As the activation temperature increases, the interlayer spacing generally exhibits a decreasing trend, indicating that the carbon structure tends to become more ordered and graphitized at higher activation temperatures.

In terms of longitudinal Poisson’s ratio, ν 12 , the results show that Glass-R exhibits a decreasing trend from 0.3 to 0.2 as Vf increases, while Carbon-HR remains approximately constant at 0.3.

As carboxyl content increased, crosslink density significantly increased, leading to marked improvement in tensile stress at given elongation, tensile strength, and hardness, while elongation at break showed a decreasing trend.

Figure 11 b reveals that when the temperature reaches approximately 1350 °C, the sample height exhibits a decreasing trend with further temperature increase, suggesting the onset of melting around this temperature.

The ballistic performance of PE/WPU X initially increased before exhibiting a decreasing trend.

However, cellulose- and xylan-related peaks showed a decreasing trend, implying that the dissolution or degradation of cell wall components led to the leaching of lignin and carbohydrates during hydrothermal pretreatment. 3.1.3.

Similar to the fitting characteristics of BPN values, the final attenuation value a of MTD values shows a decreasing trend with the increase in temperature, and the attenuation rate k increases with the increase in temperature.

Additionally, the water content of GY exhibited a decreasing trend throughout the developmental stages and was significantly lower than that of TY, with the most pronounced difference observed at maturity stage, where GY showed a 1.3-fold lower value than TY.

Conversely, at the same TSB level, the soil pH exhibited a decreasing trend with an increasing PE-MPs concentration (from M0 to M3).

However, when the reaction time was extended to 36 h, the particle size began to exhibit a decreasing trend.

In contrast, untrained groups demonstrated a decreasing trend in 25(OH)D 3 concentration 30 min post-exercise, but this difference was not significant.

In the calibration analysis of the precipitation phases, the Ni/Si atomic ratio showed a decreasing trend, while multiple Cr-containing Ni-Si-Cr ternary precipitation phases also formed in the alloy.

For example, as the glycerol content increases, the crystallization temperature and melting point of the PVA film show a decreasing trend, and toughness increases while the modulus decreases [ 23 ]. 2.2.

In contrast, NO 3 concentration was not significantly affected by the treatments ( p = 0.068); however, a decreasing trend was observed.

The ionic conductivity of the NPAM and APAM groups showed a decreasing trend with increasing dosage, whereas the CPAM group showed the opposite trend.

With increasing concentration of HATA, the apparent viscosity (AV), plastic viscosity (PV), and yield point (YP) of the drilling fluid, both before and after aging, exhibited a consistent upward trend, while the API fluid loss and HTHP fluid loss showed a decreasing trend.

At 70 °C, however, the total saponin content showed a decreasing trend.

The plot shows a decreasing trend in MPIW as the time index increases.

The time-domain signals can, as a whole, reflect the influence of damage evolution on the specimen response; that is, the amplitude of the detected signals generally shows a decreasing trend with increasing damage severity.

Although a decreasing trend in choroidal index values was associated with longer diabetes duration, no significant differences were identified among the DM subgroups following statistical adjustment.

A decreasing trend was also observed in HDL-C levels following IT treatment, although the magnitude of change was less dramatic.
