怎样判断修饰词? this specification defines minimum workmanship requirements for welding of miscellaneous equipment , vessel internals and steel structures of packaged units and shall apply when included in a request for quotaion, purchaser order or shown on the equipment specification sheets. it shall not be used for primary process equipment or equipment subject to any pressure vessel code. 本文是对成套装置中杂项设备、容器内件和钢结构在焊接方面的最低工艺要求的定义，并按照询价书、采购订单中所附要求或设备规格表中显示要求的规定。本文不得用于 主要工 艺设备 和遵照压力容器规范要求的设备。 从这段话可以看出，焊接共涉及到五类设备/设施： miscellaneous equipment ， vessel internals， steel structures of packaged units ， primary process equipment（主要工艺设备） ，equipment subject to any pressure vessel code， 本规范适用于前三类，不适用于后两类。不可能只针对packaged units 和primary process equipment 制定规范吧，况且miscellaneous equipment 应该是与primary process equipment 相对应的。 还是坚持认为一楼的问题应该理解为“成套设备的钢结构”。 查看更多
