The phrase "attenuated by adding" is correct and usable in written English.
It can be used in contexts where you want to describe the process of reducing the intensity or severity of something by incorporating additional elements.
Example: "The effects of the medication were attenuated by adding a lower dosage to the treatment plan."
Alternatives: "diminished by incorporating" or "reduced by including".
Such a drift can be significantly attenuated by adding an enthalpy reservoir to the cryocooler, separated from its cold finger by a heat switch.
However, the effects of L-4 on the cell viability, GR activity, GSH/GSSG ratio, reactive oxygen species level, mitochondria dysfunction and apoptosis induction were remarkably attenuated by adding the reactive oxygen species scavenger, NAC.
In the present study, the increase in V-V laxity in the ACL-deficient knee was attenuated by adding posterior tibial load because the anterior tibial translation was restrained.
We hypothesized that the V-V laxity in the isolated ACL-deficient knee under V-V torque was greater than that in the intact knee, and that the laxity in the isolated ACL-deficient knee was attenuated by adding posterior tibial load.
HG-elevated fibrogenic collagen IV protein expressions, was attenuated by adding ≥10 μg/ml Oryeongsan.
Weight increased similarly with both high-fat diets, but the degree of impairment in glucose tolerance was markedly attenuated by adding leucine.
As we will see later, in the field tests, this effect has been attenuated first by adding an extra care in positioning the illuminators, and second because shiny parcels are very uncommon in practice.
Both effects were attenuated by IP and could be reversed by adding back exogenous cytochrome c (Pasdois et al., 2011; 2012).
The fluorescence signal of cytoskeletal proteins in the cells treated with ultrasound alone was partially attenuated, and this attenuation was greatly enhanced by adding curcumin.
When needed, additional attenuating layers are realized by adding physical apertures.
Such bias was eliminated or attenuated by making participants explicitly aware of "cooperative", "cheating" and "neutral/indifferent" behaviors via a pre-test questionnaire and then adding such tags to behavioral descriptors (experiment 3).
