The ideal gas equation has already become the basic knowledge of physics curriculum and the physical formula that must be observed, but the volume of gas in the free space of the at-mosphere is not fixed. The air density at the formula is directly proportional to the pressure, which will conflict with some phenomena. This paper uses altitude H instead of pressure P to obtain free space air density to indicate that the air density with altitude in-creases exponentially, and leads a negative correlation with temperature. At the same time, the air of the free space should gather from the high pressure place to the place where the pressure is low. It means that the higher the altitude, the lower the pressure, and the air density will increase. The air density calculation formula is deduced from the gaseous equation, and it Calculates a result that troposphere air density at 12 kilometers has increased 15 times than the standard atmospheric pressure P0, and the exosphere at 1000 kilometers has increased 187 fold. Of course, this conclu-sion is totally opposite with the basic knowledge of “the higher the altitude, the thinner the air”. The reason is perhaps that we neglect the matter named H which has natural content of 99.985%. From this, we can have a corollary that any matter in atmospheric space may be divided into the most simple-matter-H (proton). It will become “neutron” when losing the orbital electrons at the ionized layer, and then it will “escape” into the universe to constitute new materials and planets in a new way and new form. This may be a way by which the earth's materials exchange with the planet’s materials through the atmosphere.
