The phrase "a systematic trend of" is correct and usable in written English.
It can be used when discussing a consistent pattern or tendency observed over time in a particular context or data set.
Example: "The study revealed a systematic trend of increasing temperatures over the past century."
Alternatives: "a consistent pattern of" or "an organized tendency of".
For the two Al alloys random fluctuations occurred, while for mild steel a systematic trend of potential versus current was observed.
Article 19, which campaigns globally for freedom of expression, has identified a systematic trend of abuses, specifically violations of the right to freedom of expression in the North Caucasus.
A systematic trend of the electronic contribution is demonstrated as a function of electron-to-atom (e/a) ratio and the ground-state electronic configuration of the solute atom.
Among the investigated microbial functional groups, nirS and anammox bacterial 16S rRNA genes exhibited a systematic trend of decreasing and increasing abundance, respectively, with distance from the inlet, which suggested that the functional groups respond differently to changing environmental conditions.
As seen from Figure2a, there is not a systematic trend of hole mobility with increasing N concentration in contrast to the n-type samples.
In QDs, we found a systematic trend of caused by the imbalanced magnetic responses of inter-particle Coulomb interactions, which could be observed only when the confined electron and hole wave functions exhibit a large difference in their lateral extents.
In the OC method, the results of different numbers of collocation points for two oil reservoirs demonstrate that there is a systematic trend for the odd and even number of collocation points while the former has less error than the later.
Since there was little evidence of a systematic trend in the number of outliers at either Hb extreme, ABG analysis appears to provide a consistent approximation of the Hb concentration for most Hb values seen within the ICU setting.
The relative complex viscosity curves also revealed a systematic trend with the extent of exfoliation and showed promise for quantifying the hybrid structure of the nanocomposites.
Our study indicates a systematic trend towards more comprehensive methods of evaluation, study perspectives and study designs.
As can been seen from the comparison of studies published prior to 1999 and those published between 1999 and 2004, there seems to be a systematic trend towards more comprehensive methods of evaluation and study designs.
