Bibliographic record
Abstract
Abstract Dielectric spectroscopy technique is used in this work to study the structural changes inside lead zirconate titanate (Pb (Zr,Ti)O3 or PZT) exposed to hydrogen for 24 h at 550 °C, at constant pressure p = 0.13 bar. The results show that even after hydrogen treatment, there are still spontaneous dipoles (TiO or ZrO) inside the PZT. However, the dielectric constant is only about half of that of the as‐received sample. After the hydrogen treatment, two relaxation peaks were observed in the dissipation factor curves. While the kinetics of one of the relaxation peaks obeys the classical Arrhenius law, the other peak shows a non‐monotonic relaxation kinetics. Possible reasons for the formation of these peaks have been discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
