Abstract

fetched live from OpenAlex

The pyrolysis mechanism of carbon matrix compound CH3-Ar-CH2-NH2 was studied. Using the AM1 method and UHF calculation in Gaussian 98 program package, thermodynamic and kinetic data for 5 types of designed pyrolysis path of the compound were calculated. The calculation result showed that the reaction producing CH3-Ar-CH2 and NH2 is the main pyrolysis reaction path. The calculated activation energy is Ea=230.78kJ/mol, while the experimental apparent activation energy of the compound is Ea=206.78kJ/mol. Comparing with experiment data demonstrated that the calculated bond energy parameters are reliable. Parts of the optimized geometry parameters of the reactant and production free radicals were analyzed. After the compound CH3-Ar-CH2-NH2 as carbon matrix compound are Pyrolyzed, the equilibrium geometries of produced free radicals show that plane orientation of the polymeric ring aromatic moleculars will be good when free radicals polymerized are fused aromatic ring structure.

Teacher imitation

Not 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.
