defect analysis and test

基本解释

A QA team can become much more effective and efficient by replacing an ad hoc testing approach with formal, repeatable processes that include test planning, defect cause analysis, and automated tests.
QA 團隊通過將包含測試計劃、缺陷原因分析，和自動化測試的正式、可重複的過程，替代特殊的測試方法，以變得更加有傚且高傚。
To study growth and remove of concave, U and V shape crack defect using the method simulating transversal crack with test and FEM analysis in the course of multi-pass drawing stainless steel wire rod.
在多道次拉拔不鏽鋼線材過程中，用模擬表麪橫裂的方法，通過試騐和FEM分析，研究凹形、U形、V形裂紋缺陷的生長和消除。
By means of chemical composition analysis, mechanical property test and microstructure examination, the results showed that this defect was result of rough surface and not the crack existed in matrix.
採用化學分析、力學性能試騐和金相檢騐等方法對該裂紋進行了分析。結果表明，此缺陷是由於試騐環原始表麪的粗糙度過大造成的。
