The real "revolution" in textiles was in 1770 when power-driven machinery introduced.

纺织业的真正"革命"发生在1770年，当年引进了水力驱动的机器。

Before the end of the 18th century, power-driven machines spinning two hundred threads simultaneously had been introduced in production.

在18世纪末以前，可同时纺出两百根纱的水力纺纱机已普遍应用于生产。

Twice a year Northwestern Georgia celebrates its cultural traditions on the grounds of a historic water-powered mill. The Prater Mill, located on the Coahulla Creek, was built by Benjamin Franklin Prater in 1855. During the Civil War, the mill was used as a campsite for soldiers on both sides. Since it was considered an important source of food, it was not destroyed. The Prater family operated the mill until the 1950s.

住在乔治亚西北部的居民，每年会在具历史意义的水力面粉厂内举办两次庆祝当地文化常规的庆典；座落于 Coahulla Creek 的普拉特面粉厂建于1855年，建造者是班杰明普拉特；内战时，这间面粉厂曾被敌对的双方拿来做为军营，因为它是重要的食物来源，所以未遭摧毁；直到1950年前，这间面粉厂的经营者一直是普拉特家族。

Then, precede the design of the water system and make sure the style of the water system.
