Abstract
The graft copolymer of starch St-g-DAC were synthesized through corn starch(St.) and aacryloxye-thyltrimethyl ammonium chloride(DAC) with potassium peroxydisulfate(KPS) as initiator in water solution.The process was optimized through orthogonal tests,the best reaction condition was that the weigh of initiator was 0.15g,the ratio of St and monomer was 1∶3,the reaction temperature was 55℃,the St-g-DAC was synthesized based on this conditions,its cationic ratio was 48.34%,graft ratio was 82.18%,the DAC had been grafted to starch successfully through its structure which was characterized by Fourier transform infrared spectroscopy(FTIR),and the flocculating properties of starch graft acrylamide(St-g-AM),polyacrylamide(PAM) and St-g-DAC were contrasted through jar test for clay water suspension and sewage.The result shows that St-g-DAC is a better flocculant,it has better flocculating performance than PAM and St-g-PAM for clay water and sewage treatment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
