    "经典 PDR 模型（光电加热 + 线冷却）：PAH/小尘粒光电效应提供加热，C+ 158 μm、[OI] 63/145 μm、CO/H2 线冷却平衡；可复现多数区域，但对 [CII]/FIR 缺陷、T_gas−T_dust 解耦与高-J CO 过激发的解释受限。",
    "XDR/CRDR 场景：X 射线/宇宙线主导加热可抬升 T_gas 与压力，但在普通盘区常过度提升 [OI]/[CII] 或破坏 CO SLED 斜率；参数退化强。",

    "尘气比/发射率变化：假定 DGR/κ_ν 空间变化与束填充效应可移动 [CII]/FIR 与 T_dust 零点，但在同一数据处理口径下往往留下系统性偏差。"
