Abstract
Based on the technology of contemporary climatic statistics、diagnosis and prediction and kriging insert-value means of geo-statistic method,the temperature,precipitation and runoff date in recent 48 years from 6 weather stations in Zhang-ye region were analyzed,the change scope of temperature,precipitation and runoff showed visible.The result showed that:(1)The mean temperature of Zhang-ye region was from 3.97℃ to 8.04℃.The ascending trend of mean air temperature at Shandan was the most obvious and the tendency rate of air temperature was 0.47℃/10a;the slowest was at Gaotai and the tendency rate of air temperature was 0.19℃/10a.The warmest climate occured in 1998 and the mean air temperature was 9.06℃;the coldest was in 1956 and the mean air temperature was 2.5℃.(2)The precipitation distributing was imbalance and the range of change of precipitation was above 200mm in the different zone.The precipitation changed from 67.11mm to 193.30mm in the summer,and was from 4.69mm to 10.48 in winter.The results showed that the precipitation distributing was imbalance in different season and its variety scope was different in the winter and summer.(3)The abrupt change of air temperature in Zhang-ye started from 1991,and the air temperature ascending tendency was obvious.The abrupt change of air temperature in west branch area was same as Zhang-ye region.The abrupt change of air temperature of east branch area began in 1993,and drop behind 2 years compare with Zhangye region.The abrupt change of prediction in Zhang-ye region did not happened.The periodic phenomenon of precipitation was remarkable,and the first main period of precipitation was 15a and the second mian period was 7a,but the periodic phenomenon of air temperature was not remarkable.(4)The temperature of plain was not the impact determinant of runoff,but the impact for runoff was active.Although precipitation accorded with runoff in space-time and the trend of change was decreasing,the change scope of runoff was more great than precipitation.

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
