"理論推導"(theoretical derivation)是一個在科學和工程領域廣泛使用的術語,它指的是基于已知的、已被接受的理論、原理、定律或數學模型,通過邏輯推理和數學運算,系統地得出新的結論、公式、關系或預測的過程。其核心在于不依賴于直接的實驗測量或經驗數據,而是通過嚴密的邏輯鍊條從基本原理出發進行演繹。
以下是其詳細含義的分解:
基礎與起點:
過程與方法:
目标與結果:
與實驗和經驗的關系:
在工程中的價值(體現):
總結來說,"理論推導"是一種從基本科學原理或數學公理出發,通過嚴格的邏輯推理和數學運算,得出特定結論或公式的理性研究方法。它是連接基礎理論與具體應用、預測和解釋現象、并體現工程學科專業深度與嚴謹性的核心過程。
來源參考:
"theoretical derivation" 是一個學術常用詞組,由兩部分構成:
theoretical(理論的)
指基于抽象概念、原理或假說的,而非實驗或經驗觀察的。例如:物理學中的弦理論()就屬于理論框架。
derivation(推導)
指通過邏輯推理或數學運算從已知原理得出結論的過程。例如:牛頓從運動定律推導出萬有引力公式()。
組合含義:指基于已有理論體系,通過邏輯和數學方法逐步推演新結論的過程。常見于以下場景:
與實證研究的區别:理論推導依賴邏輯自洽性,而實證研究依賴實驗數據驗證()。例如量子力學中的薛定谔方程先有理論推導,後期才被實驗證實。
