the technology they introduced meant that metal and leather goods were produced there for the first time.
请问：其中"they introduced"用于修饰"the technology"，那这里的"meant that"在这里怎么理解呢，还有"meant"为什么要用过去式呢？ 谢谢

这句话的意思是：他们提出的技术意味着金属和皮革货物第一次被那里生产.
they introduced 后置修饰the technology ，因为这个技术是过去提出的，所以用过去式

the technology they introduced meant that metal and leather goods were produced there for the first time.
他们引进的技术已表明那些金属和皮革产品是首次从他们那里生产的.
they introduced 修饰the technology 做定语，meant 是谓语动词，that是连接词引导后面的宾语从句。因为引进技术是过去发生的，所以mean用过去式。
