As one of practical methods of non - destructive testing ( ndt ) , ultrasonic testing is widely used in various departments of industry 超聲波檢測,作為無損檢測的一種常用方法,已廣泛應用于工業(yè)生產(chǎn)各個部門。
Non - destructive testing ( ndt ) is a type of technology that detects and evaluates flaws in material without affecting its internal structure 無損檢測是在不損害被探測對象使用性能的條件下探測物體內(nèi)部缺陷的技術(shù)。
Non - destructive test ( ndt ) for concrete ; inspection , evaluation and appraisal for the quality , flaw , crack and durability of concrete construction ; and sound wave test for rock 咨詢專業(yè)特長:混凝土無破損檢測技術(shù);混凝土質(zhì)量、缺陷及耐久性檢測、評定、鑒定;巖體聲波檢測。
New material , new method and new theory are the basis of the non - destructive testing ( ndt ) development , and credible flaw identification , quantitive analysis and non - destructiveevaluation ( nde ) are the main research of ndt 新材料、新方法、新理論的研究是無損檢測發(fā)展的基礎(chǔ),缺陷的可靠識別和定量檢測,以及在此基礎(chǔ)上實現(xiàn)的無損評估是其主要的研究內(nèi)容。
The metal magnetic memory testing is a new technology which is special diagnose ferromagnetism materials with applied stress in earlier , and is belong to electromagnetic non - destructive testing ( ndt ) . so the fundamental theory of ferromagnetics and the mechanics property and the electromagnetism property of metal is the theoretical foundation , some knowledge connected to them are summarized in this dissertation 磁記憶無損檢測技術(shù)是專門針對受力鐵磁性材料實施早期診斷的新型無損檢測技術(shù),其檢測的范疇還是屬于電磁方法檢測,因此有關(guān)鐵磁學的基本理論、金屬的力學特性以及電磁特性等是研究磁記憶無損檢測的理論基礎(chǔ),本論文針對有關(guān)這方面的一些基本知識作了簡要的總結(jié)。
