解释：
- Retrofit这个单词既可作动词使用，又可以充当名词。做动词时其表示“substitute new or modernized parts or equipment for older ones”这一含义，通常表达为retrofit something，即“改进/翻新/翻新改造”，与rebuild/reconstruct这些单词构成近义词。当我们说retrofit an old machine with new panels and bolts时，其核心是在表达用新的panel和bolts去替换以前老的零部件。这里核心意思是当一个“设备”的某些旧部件出现问题时，用新的东西进行替换。
- Retrofit也可以当名词用，其表示“a component or accessory added to something, or the act of adding a component or accessory to something”这一含义，即“零件/部件”或“翻新、升级行为”，与component/addition构成近义词。
