英语翻译
To ensure that the supplier's products and process reflect ·state-of-the-art·of the respective industry,the supplier shall maintain a continuous improvement process that uses all relevant feedback information such as field returns,line rejects,quality-meetings,quality-reporting etc.
主要问题有2个
1,state-of-the-art,翻译成当前最高工艺水平是否准确
2,field怎么翻译好?
里面的line rejects怎么翻译?
在其他地方我也看到过line stoppage
line应该是生产线吧 rejects 是指次品还是指别的什么吗？
还请达人指点
