The improvement on the barometric formula in isothermal process of the gas

Replacing the equation of the quasi-static isothermal process by the quasi-static polytropic process of the ideal gas, the barometric formula of polytropic process is deduced, which is better improvement on the barometric formula of isothermal process.
