熱力學平衡(thermodynamic equilibrium)是熱力學中的一個核心概念,指一個孤立系統在不受外界幹擾時,其宏觀性質(如溫度、壓強、化學勢等)達到穩定且均勻分布的狀态。此時系統内部不存在能量或物質的淨流動,所有可觀測的宏觀參數不再隨時間變化。
具體而言,熱力學平衡包含三個子平衡條件:
微觀上,熱力學平衡允許分子持續運動(如布朗運動),但宏觀統計平均值保持恒定,這體現了熱力學統計物理的基礎原理。該概念廣泛應用于相變分析(如水的汽液相平衡)、電池電動勢計算,以及恒星能量輻射模型等領域。例如,NASA對太陽内部等離子體平衡狀态的研究表明,其核心溫度維持在約1500萬K以實現核聚變反應的持續穩定。
熱力學平衡(thermodynamic equilibrium)是熱力學中的一個核心概念,指一個系統在無外界幹擾時,其宏觀性質(如溫度、壓力、濃度等)達到穩定且不再隨時間變化的狀态。以下是詳細解釋:

熱力學平衡是研究熱力學過程的基礎假設。現實中完全平衡難以實現(如恒星内部),但該模型為分析能量轉化、化學反應方向(如熵增原理)提供了理論框架。
