Calculation of diffusion behavior of pure solvents through linear low-density polyethylene (LLDPE) membrane
Bibliographic record
Abstract
The diffusion behaviors of five kinds of pure solvents through LLDPE membrane were investigated by experimental and numerical methods in order to evaluate and predeterminate the anti-infiltration performances of linear low-density polyethylene(LLDPE) sealing material.The permeation flux and equilibrium absorption capacity in the LLDPE membrane were obtained from steady pervaporation experiments and swelling experiments respectively.The diffusion coefficient was described by Fujita free volume theory and the parameters in the model were obtained by fitting a numerical solution of the flux equation to experimental data.The calculated fluxes using the free volume model accorded well with experimental results.The calculated diffusion coefficients for five kinds of solvents in LLDPE at different temperatures were drawn based on the mathematical model.Mass concentration distribution curves for five kinds of solvents in the plate membrane were calculated by numerically solving the partial different equation of Fick's second law.Results showed that LLDPE material had excellent anti-infiltration performances for five solvents.

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.
