Second, the place where the steam engine was invented: Britain.

Third, the significance of the invention of the steam engine: it promoted the development of machinery industry and even society, solved the most critical problems in the production of large machines, and promoted unprecedented progress in transportation.

With the development of steam engines, thermodynamics and mechanism have laid the foundation for the development of steam turbines and internal combustion engines. Steam turbine inherits the characteristics of steam engine using steam as working medium, adopts condenser to reduce exhaust pressure, and abandons the shortcomings of reciprocating motion and intermittent steam intake.

The internal combustion engine inherits the basic structure and transmission form of the steam engine, and forms a thermal cycle with much higher thermal efficiency by directly inputting fuel into the cylinder for combustion. At the same time, cylinders, pistons, flywheels, flying hammer governors, valves and seals used in steam engines are the basic components of many modern machines.

Development history of steam locomotive;

18 14, the first steam locomotive "Pioneer" developed by Stephenson was successfully put into trial operation. 1On September 27th, 825, Stephen Sun personally drove the Voyager steam locomotive designed and manufactured by him in cooperation with others on the newly laid railway, and achieved success. The application of the steam engine in the transportation industry has enabled mankind to enter the "train era" and rapidly expanded the scope of human activities.

Stephenson successfully commissioned Brazer locomotive in 18 14, but it also exposed many problems, such as too much noise and strong vibration, and the steam engine may explode at any time.

However, Stephenson is not discouraged, but keeps improving. He installed damping springs under the carriage, used wrought iron instead of pig iron as the rail material, laid pebbles under the sleepers, increased the number of wheels in the front and carriage, and installed a steam engine in the front to reduce the damage in dangerous situations.

By 1825, when Stephenson tried to run Voyager, the situation improved considerably. Voyager is towing six coal trucks and 20 carriages full of passengers, with a load of 90 tons and a speed of 15 miles per hour. With the sound of the train, it announced the arrival of the railway era to the whole world.

1829, Stephenson successfully trial-produced a more advanced "rocket" locomotive.
