"expansion coefficient" 的中文術語是膨脹系數。它是一個重要的物理量，用于描述物質（通常是固體、液體或氣體）在特定條件（最常見的是溫度變化）下，其尺寸（如長度、面積、體積）發生變化的程度。
其核心含義可以理解為：
主要類型：
線性膨脹系數：
體積膨脹系數：
重要性和應用：
膨脹系數（尤其是熱膨脹系數）在科學和工程領域至關重要：
常見材料的膨脹系數參考值示例：
膨脹系數（Expansion Coefficient），特别是熱膨脹系數，是一個描述物質尺寸（長度或體積）隨溫度變化而相對變化的物理參數。線性膨脹系數 ($alpha$) 描述長度變化，體積膨脹系數 ($beta$) 描述體積變化。它在材料科學、工程設計、精密制造等領域具有廣泛應用，是确保材料或結構在溫度變化環境下性能可靠的關鍵參數之一。其數值和單位（通常為每開爾文 K⁻¹）是材料固有的熱物理性質。中國國家标準化管理委員會發布的相關材料測試标準（如 GB/T 4339-2008《金屬材料熱膨脹特征參數的測定》）為測量膨脹系數提供了規範方法 [SAC GB/T 4339-2008]。
“Expansion coefficient”（膨脹系數）是一個多學科術語，其具體含義需結合使用場景理解：
指物質在溫度變化時體積或長度變化的比率，用于衡量材料的熱膨脹特性。例如：
在時間序列分析中，該術語指通過向量映射将高維時間序列壓縮為低維特征向量的過程，用于存儲序列内在信息。
建議具體場景中結合上下文判斷其含義，工程問題優先參考物理定義，數據分析領域則可能涉及特殊映射算法。
