| Abstract: | The atmosphere was approximated as the van der Waals gas. Using polytropic process instead of isothermal process, we deduced the barometric formula of van der Waals gas in the polytropic process, which is the better improvement on isothermal barometric formula of the ideal gas. |

| Keywords: | van der Waals gas polytropic process barometric formula |
