Abstract
Air samples were collected using an improved high volume active air sampler in May 7 to 20,2008 in Harbin City.Concentrations of polycyclic aromatic hydrocarbons(PAHs) in both gas and particle phases were measured.Total PAHs concentration ranged from 8.1 to 37.2 ng/m3,with an average of 18.2 ng/m3 for all samples.Sources of PAHs were identified by diagnostic ratios of some individual PAHs,which indicated that the dominant source in Harbin was coal combustion.Lower ring PAHs dominated in the gas phase,while the major higher ring PAHs were adsorbed on particle phase.While good correlation was found between gas-particle partition coefficients of PAHs and the respective sub-cooled vapor pressures,non-equilibrium between gas and particle phases was obtained possibly due to the new produced PAHs from coal combustion in winter.

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
