interstellar gas

According to the actual volume of gas molecule and effort between molecules influencing the gas action, in the Van der Waal formula of ideal gas state, the amending terms of n~2a/v~2 and nb is introduced and then the formula (p+n~2a/v~2)(v-nb)=nRT forms to describe the actual gas action.
