Abstract
The gas puff is one of the main loads used in Z pinch research. In this paper the basic physics process of the Laval nozzle on Qiangguang I generator is analyzed using one dimension isentropic gas dynamics equation.The Mach number 4.6 of the gas flow is calculated and corrected as 3.5 considering the effect of boundary. Combining the data of gas puff Z pinch experiments on Qiangguang I generator, the expression of the line mass is obtained using the implosion time expression which is deduced from snow-plow model. In the end of the paper the distribution of the gas density is given by the Bollistic-Transport (B-T) model and the gas density is between 10~(16)/cm~3 and 10~(17)/cm~3. Along the axis within 2 cm, a hollow gas shell structure is formed.

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
