The application of the global isomorphism to the surface tension of the   liquid-vapor interface of the Lennard-Jones fluids
  In this communication we show that the surface tension of the real fluids of the Lennard-Jones type can be obtained from the surface tension of the lattice gas (Ising model) on the basis of the global isomorphism approach developed earlier for the bulk properties.
