VI. 总结性评价

优势

  1. 统一乘性结构(S01–S05) 同步刻画 A_loop/e_loop/Δφ_T/τ_lag/κ_dust/Σ_ice/ΔSt/C_ring/J_cond/J_sub/ε_mass/ε_disp/BW_coh 的协同演化,参量物理含义明确,可用于锁相带识别、尘环工程化诊断与观测配置优化。
  2. 机理可辨识:γ_Path/k_Topology/k_Recon/k_SC/θ_Coh/ξ_RL/η_Damp/k_STG/k_TBN 的后验显著,区分迟滞回环单调雪线漂移
  3. 应用价值:基于 A_loop–ΔSt–C_ring 标度,可筛选行星胚形成视窗并规划多波段时域联测。

盲区

  1. 高光学厚度与散射各向异性可能偏置 κ_dust 与 C_ring,需辐射转移校正。
  2. 亮度时序抽样不均会影响 τ_lag 与 A_loop 的稳健性,需密集采样策略。

证伪线与实验建议

  1. 证伪线:当 EFT 参量 → 0 且 A_loop、Δφ_T、ΔSt、C_ring、ε_disp 的协变关系全部消失,同时主流辐射平衡+α-disk+一维冰线模型在全域满足 ΔAIC<2、Δχ²/dof<0.02、ΔRMSE≤1%,则本机制被否证。
  2. 实验建议
    • θ×t 相图:构建角向—时间相图量化 BW_coh 与锁相带迁移;
    • 多波段同步:ALMA(B6/7)+ERIS+SPHERE+MIRI 同步时序,稳健估计 Δφ_T、τ_lag;
    • 质量闭合:联合 J_sub/J_cond 与尘谱演化约束 ε_mass;
    • 动力学交叉:CO 同位素与热尘联合获取 ΔSt,验证跨雪线颗粒动力学跃迁。
