This is the turbine to compressor mechanical advantage mentioned earlier that is employed in jet engines and is key to making them work!
这是机械的优势，以压缩机刚才是受雇于喷气发动机，关键是使他们的工作涡轮！

Dry plasma cutting: also called the air-filled type cutting, the air compressor to plank cut in order to achieve the effect of cooling seam jet, such cutting costs low, but pollution is very large.
