Abstract
Based on the technologies of gas atomization,supersonic gas atomization,surface effect of electric charges and jet technology,a novel atomization device of two fluids atomization with the combination of solid atomization and electric field is designed utilizing a LAVAL nozzle,delivery tube of sectional type and electrical field dispersion technique.The 63 A soldering tin was atomized with the air,and the powder prepared was analzed by optical granularity analyzer,analyzer of size distributions and Zeta electric potential analytic instrument.The results show that the powders with less than 8 μm can reach 75%;the average size is 1.761 2 μm,and the first peak in the distribution curve is around 500 nm,which is an order of magnitude smaller than that the reported peak.The compound atomization device can refine the powder effectively,improve uniformity,yielding rate,and the purity of atomized powders and has a significant atomization effect,thus provides powerful supports for preparing fine metal powders with high efficiency and low energy consumption and has a good prospect in the application.

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.
