Effects of freezing and steam treatments on the permeability of Populus tomentosa
Bibliographic record
Abstract
Abstract In order to improve the material properties of Populus tomentosa, and increase its utilization rate for furniture products. Two modification methods, including freezing and steam treatments were adopted in this work, and special attention was given to the permeability of Populus tomentosa with respects of processing time, temperature and moisture content. According to the experimental results, the optimum modification parameters for Populus tomentosa with freezing treatment are processing temperature of ‐20 °C, time of 2 hours and saturated moisture content; while the optimal modification parameters with steam treatment are as follows: processing temperature of 120 °C, time of 2 hours and saturated moisture content. Based on comparing the weight gain rate at different processing condition, steam treatment has greater influence on the permeability than that of freezing treatment. In general, steam treatment was proposed to be used in the property modification of Populus tomentosa in terms of greater permeability.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
