Electrohydrodynamic surface waves of thin oil films generated by needle-plate barrier discharges under argon gas environments
Bibliographic record
Abstract
The study of electrohydrodynamically (EHD) induced surface wave phenomena on the surface of dielectric thin oil films under needle-plate barrier discharges for argon gas reduced gas pressure environments has been investigated experimentally, Experiments were conducted in a cloud environmental chamber maintained at gas pressure from 5.1 to 760 Torr. The test system consisted of needle corona electrode gaps, thin mineral oil films, polymer sheet and metal grounded plate. DC (on/off) negative and positive voltages were imposed on needle electrode. Measurements of corona current waveform and surface wave were observed by current transformers and CCD video camera, respectively. Unlike corona discharge in air, Ar discharge will not generate any negative ions, hence only glow corona was observed. The results show that thin oil film started to deform immediately who positive or negative dc voltage was imposed and after voltage was off, and that a formation of depression expanding waves was observed in argon gas when gas pressure was between 11 to 760 Torr for positive applied voltages only.

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.
