请问 vessel trim 什么意思? http:///invi ... dex.php/t3408.html. 该网址提供的内容中有两个概念： vessel trim和vessel trim number，摘抄一点相关内容: basically what i understand from description is trim number is only pipe class or spec of the piping used around that equipment or is it instruments mounted around equipment . .............................. 3) i am not a native english speaker, but when i look into a dictionary, one of the defintions of trim is: "exterior ornamentation, such as moldings or framework, on a building or vehicle." with a little bit of fantasy, these loose piping items can be considered exterior ornamentation of the vessel. 查看更多
