| Abstract: | The polynomial fitting of the saturation pressure is presented by the minimum square estimating methods,with NASA's database on hydrogen and oxygen.It is useful in practice for the calculation in hydrodynamics and combustion of hydrogen and oxygen.To calculate the saturation vapor pressure with the formula in the paper,the fussy in calculation with the database and the inconvenient in calculation with popular software can avoided. |

| Keywords: | saturation vapor pressure critical pressure critical temperature |
