The phrase "a declining gradient of" is correct and can be used in written English.
It is typically used when referring to a decrease in a particular metric or measurement. For example, "The temperature had a declining gradient of 5 degrees over the course of the day."
Because the P-D length of the uncondensed distal tip of the chicken limb bud decreases during the period of pattern formation [54] as the potency of the AER wanes [10] we have incorporated into our model the hypothesis that a temporally declining gradient of FGF with its source in the AER determines the P-D length of this distal region, which we term the "LALI zone".
Cadmium accumulated in the shoot tissues (especially the leaves) in a declining gradient towards the head, a pattern that is typical of cereals [ 20, 27, 28].
Following application of trace quantities (250 pM) of Cd to the fourth stem-internode of intact durum wheat, Cd accumulated in the stem in a declining gradient towards the spike [ 37].
Cadmium transported to the shoots of cereals prior to anthesis accumulates in the leaves and stems in a declining gradient towards the developing spike [ 20, 27, 28].
The idea of gradient optimization of solution purification process, which transforms the economical optimization problem of solution purification process into finding an optimal decline gradient of the impurity ion concentration along the reactors, is proposed.
In contrast, a declining social gradient was associated with increased risk of mild-moderate ID.
Mean MFA followed a declining trend with a relatively steep gradient in the early years of growth (up to about age 10 years), before levelling off (Fig. 5).
They have declining density gradients of population and employment that extend outward from a station and have a high level of mixed-use land.
There is a gradient of declining FSH levels among the three subgroups of wild-type homozygotes (GG), heterozygotes (GT) and homozygotes for the minor allele (TT) of rs10835638 (ANOVA: F = 13.0, P = 0.0016, df = 1; Table I; Fig. 2).
Walking through the building is like viewing a timelapse; a gradient of construction.
