Abstract
A typical undulating farmland in black soil region of Northeast China was taken as a case study to analyze the properties of soil loss caused by erosional precipitation events based on measurement of sediment and its nutrients and particle size in different geomorphic positions and the outlet of the watershed.The results showed that soil loss only happened in high rainfall intensities.This study takes the runoff event on August 1st,2006 for example.The sediment concentration in runoff is in range of 1.0～2.5 g/L.Nutrient enrichment occurred in sediment and the enrichment ratio of carbon and nitrogen is 2.10 and 3.31,respectively.The soluble carbon and nitrogen in runoff is 2.47～3.93 mg/L and 1.61～3.28 mg/L.The loss of soluble nutrients is also an important way of nutrient loss under water erosion.The aggregate size distribution of the eroded sediment was drastically different from that of the original soil.Aggregates smaller than 0.053 mm,especially the size between 0.002 mm and 0.02 mm,is the main form of the sediment.

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
