本研究基於 Planck 2018 的宇宙微波背景(CMB)觀測數據與 DESI的重子聲學震盪(BAO)測量,針對動態暗能量模型進行觀測約束與理論回測。本文首先回顧了標準宇宙學模型(Λ-CDM)及其核心方程,並分析了現有模型在哈勃常數 H0 張力及結構生長速率等觀測上的偏差。研究中採用經超新星 Ia 校準的哈勃常數與 DESI 物質密度參數作為初始條件,提出一個可變狀態方程 wϕ (a) 的暗能量模型,並結合 CMB 角尺度 θ∗ 及 DESI 各項距離量進行模型擬合。結果顯示,本模型在描述宇宙膨脹歷史及結構形成方面,能有效降低與觀測數據的誤差,優於傳統Λ-CDM 及 DESI 公布的數個傳統模型 (w-CDM 及 w0 wa -CDM)。最後,本文亦討論未來將結構生長速率 f σ8 納入分析的潛力,期望進一步提升模型的普適性與預測能力。
