Thermogravimetric Analysis and Combustion Performance of 10 Common Types of Tree Leaves in Maoer Mountain Region
Bibliographic record
Abstract
By thermogravimetric analysis method,this paper studied pyrolysis characteristics and kinetics of 10 kinds of representative trees species grown in Maoer Mountain of Heilongjiang Province. Besides,it analyzed basic pyrolysis process of fuel using TG-DTG curve. Through pyrolysis parameters,it made quantitative comparison of pyrolysis characteristics of the different plant fuel and obtained the relation between lignin,hemicellulose and cellulose. By grading reaction kinetics model( Coats-Redfem method),it obtained their activation energy E and frequency factor A. All samples of pyrolysis in nitrogen atmosphere underwent three major stages,namely,water precipitation,fast pyrolysis and carbonization. In addition,Mongolian scotch pine and Black pinus tabulaeformis carr have better fireproof performance than other leaves with ignition temperature of 275. 17 ℃ and 274. 38 ℃ and activation energy of 44. 188 6 KJ / mol and 42. 864 3 KJ / mol respectively. Further,with the aid of the technology of relative limited oxygen index( LOI),it measured the LOI of fuel. Its numerical value can reflect the fuel combustibility. Oxygen index of elm is 26. 4% and belongs to flame resistant level,while black pinus tabulaeformis oxygen index is 20. 2% and belongs to inflammables.

How this classification was reachedexpand
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.
