Enthalpy–entropy chart
(重定向自Mollier diagram)




An enthalpy–entropy chart, also known as the h–s chart or Mollier diagram, plots the total heat against entropy, describing the enthalpy of a thermodynamic system. A typical chart covers a pressure range of 0.01 - 1000 bar, and temperatures up to 800 degrees Celsius. It shows enthalpy in terms of internal energy
