Reduced cost was also instrumental in developing steam-powered rolling mills capable of producing finished iron of various shapes and sizes.

降低的成本也有助于那些能够生产不同形状和尺寸的成品铁制品的蒸汽动力轧钢厂的发展。

As the use of new steam condensate technique, the heat energy of the steam was used more reasonable and the amount of the steam condensate was reduced obviously.

由于采用了新蒸汽冷凝水工艺技术，使得蒸汽热能得到更加合理的利用，较之原有的三组管道化新蒸汽用量明显降低。

The steam consumption is reduced, the production cost is decreased.

使之降低蒸汽消耗，降低生产成本。

Tall buildings, walkable neighborhoods, and a good transit system reduce the average cost of face-to-face interaction in exactly the same way that steam ships and low tariffs reduced the average costs of shipping goods to the other side of the world.
