defect analysis and test

基本解釋

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(tuán)隊(duì)通過(guò)將包含測(cè)試計(jì)劃、缺陷原因分析，和自動(dòng)化測(cè)試的正式、可重復(fù)的過(guò)程，替代特殊的測(cè)試方法，以變得更加有效且高效。
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.
在多道次拉拔不銹鋼線材過(guò)程中，用模擬表面橫裂的方法，通過(guò)試驗(yàn)和FEM分析，研究凹形、U形、V形裂紋缺陷的生長(zhǎng)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.
采用化學(xué)分析、力學(xué)性能試驗(yàn)和金相檢驗(yàn)等方法對(duì)該裂紋進(jìn)行了分析。結(jié)果表明，此缺陷是由于試驗(yàn)環(huán)原始表面的粗糙度過(guò)大造成的。
