超聲波檢測（Ultrasonic Inspection） 是一種利用高頻聲波（通常高于人類聽覺範圍，即大于20 kHz）來探測材料内部結構、評估材料完整性或測量厚度的無損檢測技術。其核心原理是向被檢物體發射超聲波脈沖，通過分析聲波在材料内部傳播時遇到界面（如缺陷、分層、其他材料）産生的反射、散射或透射信號的變化，來判斷材料内部是否存在缺陷、測量缺陷尺寸、位置或材料厚度等。

Ultrasonic Inspection（超聲波檢測）是一種廣泛應用于工業領域的無損檢測技術，主要用于評估材料或結構的内部缺陷或性能。以下是詳細解釋：
定義與原理
超聲波檢測利用高頻聲波（通常超過20kHz）在材料中傳播的特性。當聲波遇到材料内部缺陷（如裂紋、氣孔）或界面時，會反射、散射或衍射。通過接收和分析這些回波信號，可以确定缺陷的位置、大小和形狀。例如，在焊縫檢測中，超聲波束進入金屬後，若遇到裂縫，反射波會在儀器屏幕上形成特定脈沖波形，從而判斷缺陷。

局限性
實例說明
例如，在工業焊接中，超聲波檢查可發現肉眼不可見的焊縫裂紋，如“超聲波檢查顯示焊縫存在裂紋”（However, ultrasonic checks showed cracks in the seams）。
Ultrasonic Inspection通過聲波特性實現材料内部缺陷的無損評估，是制造業、工程維護等領域的關鍵技術。如需進一步了解操作标準或具體案例，可參考專業檢測手冊或行業規範。
