证伪线与实验建议

  1. 证伪线:当 γ_PathEW→0, λ_SC→0, ζ_Top→0, ρ_Recon→0, k_TBN→0 且 ΔRMSE<1%、ΔAIC<2,并且 A_EW/phi_shift/E_bend/κ_θ 收敛至基线(≤1σ),则对应机制被否证。
  2. 实验建议
    • E=0.5–8 GeV、Δφ=5°–10° 的细分网格上加密天顶×地磁活动分层,精测 ∂A_EW/∂E 与 ∂phi_shift/∂E;
    • 引入多台站同步(北/南半球)联合拟合,检验 RL(ξ) 的平台不变性与地磁纬度依赖;
    • 采用事件形状工程(ESE)与数据驱动的方位接受度交叉标定,降低 ρ_Recon–λ_SC 相关;
    • 结合中子监测与 μ 子通量数据,对 U_env 进行更细粒度的时间建模以提升外推稳定性。
