交通运输机械 蒸汽机的出现和使用,使煤、铁和各行各业的生产量大幅度地提高。进行大量原料和产品的运输又成为当时社会生产的需求。 在Watt之后,蒸汽机的继续发展主要是提高蒸汽的压力和温度,以及进行分段膨胀,同时推广应用到运输工具上。1800年,Richard Trevithick制成了高压蒸汽机。 Transportation Machinery The emergence and use of steam engines has greatly increased the production of coal, iron and various industries. The transportation of large quantities of raw materials and products has become a demand for social production at the time. After Watt, the continued development of the steam engine was mainly to increase the pressure and temperature of the steam, as well as to carry out segmented expansion, and at the same time to promote its application to transportation vehicles. In 1800, Richard Trevithick made a high pressure steam engine.
