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 团队通过将包含测试计划、缺陷原因分析，和自动化测试的正式、可重复的过程，替代特殊的测试方法，以变得更加有效且高效。
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.
在多道次拉拔不锈钢线材过程中，用模拟表面横裂的方法，通过试验和FEM分析，研究凹形、U形、V形裂纹缺陷的生长和消除。
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.
采用化学分析、力学性能试验和金相检验等方法对该裂纹进行了分析。结果表明，此缺陷是由于试验环原始表面的粗糙度过大造成的。
