Displacement direction of secular polar motion and the mystery of central axis shifting in Beijing
Bibliographic record
Abstract
The existence of solar pressure,earth revolution and rotation,and ecliptic obliquity,additional with geographical distribution of land and sea in earth surface constitute a set of natural physical mechanism which produces polar motion and energy coupling between sun and earth by the way of excitation of rotational axis wobble.Two distinguished periods occurred arise from wobble of rotation axis excited by solar pressure,it's so called annually periodic excitation mechanism and diurnal periodic excitation mechanism,whereas given rise to two correspondent polar motion trail whose name is annually change and diurnal change,with which some component of secular polar motion both in these track.This paper elaborate instant polar motion as well as it's characteristics and direction result from diurnal periodic excitation,and figure out the general direction of secular polar motion shift to Ellesmere Island of Canada alone western longitude 70°~80° referenced to polar M.According to author's researches,such long spread legendary enigma on why Beijing central axis skewing to meridian line reach to 2 degree anticlockwise which established at Yuan dynasty(about 800 years ago) being revealed.

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.
