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。
擴張是指增加或擴大某物的規模、範圍、數量或價值等。它可以指物理空間的擴張，如宇宙的擴張，公司業務的擴張，社會影響力的擴張等。在商業、經濟、政治等領域中，擴張往往是企業或組織的重要戰略目标。
擴張是一個動詞，也可以作為名詞使用。在動詞形式中，它通常與“of”結合使用，表示某一事物的擴張，例如：“the expansion of a city”（城市的擴張）。“Expansion”作為名詞時，可以指擴張的過程或結果，例如：“the expansion of a business”（企業的擴張）。
系數是數學中的概念，用于表示一個數在某一運算中的倍數或影響程度。在代數中，系數是指一個變量前面的數字，例如2x中的“2”就是系數。在統計學中，系數可以表示變量之間的相關性、影響力或預測能力等。
系數是一個名詞，它通常用于數學和統計學領域。在數學中，系數指的是多項式中各項的常數系數。在統計學中，系數可以表示變量之間的關系或影響程度，也可以用于回歸分析中的預測模型。
