Abstract
XRD, Raman analysis, and metallographic analysis are used to identify corrosion products of ancient bronzesexcavated from Qiaojiayuan tombs, and the result indicates that the corrosion products mainly includesCu2CO3(OH)2, Cu3(OH)2(CO3)2, Cu2O, Cu2Cl(OH)3, CuCl2·2H2O, PbCO3 and SiO2. It was found that theseancient bronzes were preserved in a chloric, acidity, and seasonal changed environment. In addition, the ? phaseof the eutectoid was corroded preferentially in this environment. There are lots of corrosion types in thesebronzes, such as electrochemistry corrosion, hole-corrosion, and dot-corrosion. The corrosion products generallyhave copper oxychloride, moisture copper chloride and other copper chlorination corrosions, and the position ofthe powdery corrosion presents the rust layer structure of “copper- cuprite- paratacamite- malachite- azurite”. Atthe same time, the corrosion principles of the bronzes are discussed, and the simple methods scientificallyprotecting these bronzes are suggested in the final part of the article.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
