帮忙翻译一下exposed unpainted machined equipment sur ...? all exposed unpainted machined equipment surfaces shall be cleaned,dried,and thoroughly treated with an appropriate quantity of an approved type of compound,which will provided an effective protective coating for a minmum of 24 months. 之所以造成理解混乱,是因为原文中前后用了两个不同的词(标红):unpainted (未漆过的),an effective protective coating (一种有效的保护涂层)。 个人赞同这种观点:coating --涂层、涂装,paint--油漆。涂层是涂在物体表面形成的一层干油漆,而油漆是装在容器里的液体。材料商对涂料和油漆都用的是paint。 更多的关于coating与paint的区别见 http:///mutual/forum_topic.jsp?id=260 查看更多
