请高手忙帮将下面两句话翻译成英语,非常急用,谢谢了!

采用空运运输的零件一般都为急需件,在仓库做短暂存储后被运输到生产线上,但现在有些空运件长时间无拉动,由于空运的费用远远大于海运的费用,所以造成运输成本上的浪费.
The parts requiring an air shipping are normally the kind in an rush order, and they would be conveyed to production line after a short time storage in warehouse, but there are still lots of air shipping articles pending inside nowadays, due to a far higher expense for air shipping compared to sea shipping, it would definitely result in a great waste of transportation charge.
