【正文】 of production. The late 17th century, with all the mechanical improvements and development, as the coal and metal ore requirements of the yearly increase, People are relying on the human and animal production can be raised to a new stage. In Britain, textile mills and other industries will be more and more factories set up by the river, and the use of turbine driven mechanical work. But, at that time, coal, tin and copper mines such as the groundwater, only with a large number of animal resources to upgrade and exclusion. In this production needs, the early 18th century there Newen the atmospheric steam engine to drive mine drainage pump. However, the steam engine of this high rate of fuel consumption, basically applies only to coal. 1765, Watt invented the separate condenser of the steam engine, reducing fuel consumption rates. 1781 watts is to create a provider rotary engine of the steam engine, the steam engine to expand the scope of its application. The invention of the steam engine and development, mining and industrial production, railways and shipping have all been of mechanical power. The steam engine to the 19th century is almost the only source of power, but the steam engine and boiler, condenser, cooling water system bulky, bulky and inconvenient to use. End of the 19th century, the power supply system and electrical began the development and promotion. The early 20th century, the motor industry has replaced the production of the steam engine, all driven into the basic mechanical work force. Mechanized production is inseparable from the electrification and electrification through mechanization only play a role in the production. Power stations initial impetus for the invention of the steam engine. Early 20th century, emerged as a highly efficient, high speed, high power of the turbine, there to keep the turbine water resources, and promote the power supply system to flourish. The late 19th century after the invention of the internal bustion engine has improved and bee light, small, high efficiency, easy manipulation, could start at any time the original motivation. It was first used to drive without an electricity supply mechanical work on land and later used in vehicles, mobile machinery and ships. to the mid20th century for railway lootives. Turbine and the steam engine in the engine exclusion, it has ceased to be an important force driving the machinery. After the invention of the internal bustion engine and gas turbines, jet engines and the development of the aircraft, Spacecraft such as the successful development of the basic technology one of the factors. Before the industrial revolution, machinery mostly wooden structure, made of wood by hand. Metals (mainly copper, iron) just to manufacture equipment, locks, clocks, pumps and wood structure of small mechanical parts. Metal processing machine Carpenter mainly rely on the intricate munications to the needs of accuracy. The steam engine to power devices in promotion, and the conitant emergence of mining, metallurgical, ships, lootives and other large machinery, Forming and processing needs machining metal parts to more, the accuracy requirements are increasingly high. Application of metal materials from copper and iron to the development of the steelbased. Forging including machining, forging, sheet metal process, welding, heat treatment technology and equipment, and machining technology and machine tools, knife, measuring tools, rapid development, and guarantee the development of the industrial production of machinery and equipment supply. Socioeconomic development of the machinery of the surge in demand for products. Mass production and the increasing precision processing technology progress, a great deal to promote the formation of production methods, such as the production of parts interchangeability, professional division of labor and cooperation, water lines and water processing, and other assembly line. Simple parts interchangeability and professional collaboration division of production, in ancient times there was already. In mechanical engineering, Interchangeability Mocili reflected in the earliest in 1797 to
