如何翻译下面两句?saturation column? feed is distributed on the top, over the hold down plat e, and is saturated by hydrogen flowing down through the inert packing.进料的分配在顶部进行,越过固定塔板,由下方的氢气流通过惰性填料进行饱和处理。 the hold down plate 填料压板 气体在塔内一般是自下向上流动的upflow,所以这里的 flowing down 应该指的是feed,而不是hydrogen。 feed is distributed on the top , over the hold down plate, and is saturated by hydrogen flowing down through the inert packing. 主句为颜色句。 __________________________fyi 查看更多
