英语翻译
By far the most important United States export product in the eighteenth and nineteenth centuries was cotton,favored by the European textile industry over flax or wool because it was easy to process and soft to tile touch.Mechanization of spinning and weaving allowed significant centralization and expansion in the textile industry during this period,and at the same time the demand for cotton increased dramatically.American producers were able to meet this demand largely because of tile invention of the cotton gin by Eli Whitney in 1793.Cotton could be grown throughout the South,but separating the fiber — or lint — from the seed was a laborious process.Sea island cotton was relatively easy to process by hand,because its fibers were long and seeds were concentrated at the base of the flower,but it demanded a long growing season,available only along the nation's eastern seacoast.Short-staple cotton required a much shorter growing season,but the shortness of the fibers and their mixture with seeds meant that a worker could hand-process only about one pound per day.Whitney's gin was a hand-powered machine with revolving drums and metal teeth to pull cotton fibers away from seeds.Using the gin,a worker could produce up to 50 pounds of lint a day.The later development of larger gins,powered by horses,water,or steam,multiplied productivity further.
The interaction of improved processing and high demand led to the rapid spread of the cultivation of cotton and to a surge in production.It became the main American export,dwarfing all others.In 1802,cotton composed 14 percent of total American exports by value.Cotton had a 36 percent share by 1810 and over a 50 percent share in 1830.In 1860,61 percent of the value of American exports was represented by cotton.
In contrast,wheat and wheat flour composed only 6 percent of the value of American exports in that year.Clearly,cotton was king in the trade of the young republic.The growing market for cotton and other American agricultural products led to an unprecedented expansion of agricultural settlement,mostly in the eastern half of the United States — west of the Appalachian Mountains and east of the Mississippi River.

迄今为止最重要的美国出口产品在十八和十九世纪是棉花,深受欧洲纺织工业在亚麻或羊毛,因为它很容易过程和软到瓦碰.机械化的纺织允许重要的集中化和扩张在纺织行业在这一时期,同时棉花的需求大幅增加.美国生产商能够满足这一需求很大程度上由于瓷砖发明的轧棉机由Eli Whitney在1793年.棉花可以种植在整个南方,但分离的纤维——或lint——从种子是一个艰难的过程.海岛棉是相对容易的手工过程,因为它的纤维长和种子都集中在花的底部,但这要求长期的生长季节,只能在这个国家的东部海岸.短绒棉需要更短的生长季节,但脆性纤维及其混合物与种子意味着工人可以手过程只有大约1磅每一天.惠特尼的杜松子酒是一种手动机与旋转鼓和金属牙齿拉棉纤维远离种子.使用杜松子酒,一个工人可以产生高达50磅的线头一天.以后的发展更大的杜松子酒,靠马、水或蒸汽,增加生产率进一步.交互的改进加工和高需求的迅速蔓延导致种植的棉花和激增的生产.它成为了主要的美国出口,超过其他所有.1802年,棉花由美国出口总额的14%的价值.棉有36%的市场份额到1810年和1830年50%的份额.在1860年,61%的美国出口的价值的代表是棉花.相比之下,小麦和小麦面粉沉稳,只有6%的美国出口的价值在那一年.显然,棉花是国王在贸易的年轻的共和国.日益增长的市场棉花和其他美国农业产品导致的农业聚落的空前扩张,主要是在东部一半的美国西部的阿巴拉契亚山脉和密西西比河东岸.
