历史上的重大发明和发现

Photos 徽标 Photos | 幻灯片 28 - 1: UNITED KINGDOM - NOVEMBER 08: The first products of the famous engineering partnership of Matthew Boulton (1728-1809) and James Watt (1769-1848) were, like earlier engines, purely pumping machines. It was only later, in about 1782, that Watt began to introduce the rotative engine that could be harnessed directly to rotating machinery, and so made possible a huge expansion of all types of industry that needed power. This engine, which drove part of Boulton's own works, is the oldest steam engine to have survived nearly complete and essentially unaltered. (Photo by SSPL/Getty Images)

蒸汽机

1698 年,英国军事工程师 Thomas Savery(托马斯·萨维利)为世界第一台蒸汽机申请了专利。然而,直到 18 世纪 60 年代,苏格兰工程师 James Watt(詹姆斯·瓦特)才发明出一种显著改进的蒸汽机版本(如图所示),这在工业革命中发挥了重要作用。
