Mechanical engineering including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. Typically, engineering thermodynamics is concerned with changing energy from one form to another. As an example, automotive engines convert chemical energy (enthalpy) from the fuel into heat, and then into mechanical work that eventually turns the wheels. Thermodynamics principles are used by mechanical engineers in the fields of heat transfer, thermofluids, and energy conversion. Mechanical engineers use thermo-science to design engines and power plants, heating, ventilation, and air-conditioning (HVAC) systems, heat exchangers, heat sinks, radiators, refrigeration, insulation, and others.
Technological and industrial history of China the People's Republic of China). This led to a shortage of skilled personnel that seriously hampered the industrial sector's implementation of imported modern technology and independent development of new management and production forms. In 1980 a modern management training center was established in Dalian, Liaoning, with the help of foreign experts. In 1987 many Dalian graduates found it difficult to use their newly acquired skills because managerial autonomy was lacking, and many cadres had a vested interest in maintaining the status quo. It was then unclear what effect students educated abroad were having on industry. China is well endowed with
