Abstract
A new environmental friendly polyurethane(PU) foam with blowing agent of HFC-245fa was developed in order to substitute for traditional foam with blowing agent of CFCs, which has been phased out according to Montreal protocol and subsequent treaties. But the coefficient of thermal conductivity of the new foam is not available at present when it is used for cryogenic storage tanks and pipes. In this paper, the mechanism of heat transfer in the foams was analyzed and a layered insulation model used at low temperatures was described accordingly. The mean apparent thermal conductivity under low temperature of the new PU foam, which has zero ODP, was investigated. The relationship between density and the thermal conductivity was experimentally studied. The results proved that the newly developed material had a better performance in thermal insulating system and provided a reference data when use the material under low temperatures.

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
