The meaning of steam engine tattoo is science and progress. The significance of the invention of steam engine is to promote the development of machinery industry and even society. Steam engine has a great historical role. It has promoted the development of machinery industry and even society, solved the most critical problems in the production of large machinery, and promoted the unprecedented progress of transportation.

With the development of steam engine, thermodynamics and mechanics have laid the foundation for the development of steam turbine and internal combustion engine; The steam turbine inherits the characteristics of the steam engine with steam as the working medium and the advantages of using condenser to reduce the exhaust pressure, and discards the shortcomings of reciprocating motion and intermittent steam admission.

The greatest advantage of modern steam engine is that it can use almost all the fuel to convert heat energy into mechanical energy. Unlike the internal combustion engine, it is not picky about its fuel. In addition, atomic energy cannot be used without a steam engine.
