摘      要：正A simple approach based on Newton’s method using Wilson activity coefficients equation and Antoine equation is presented to determine the binary homogeneous azeotropes for hydrofluorocarbons （HFCs） and hydrocarbons（HCs） *** method is verified with the binary systems of R170 + R116 and R125 + *** agreements are found between the predicted results and the literature data.
