between electrostatic field and gravitation field. We have got the equation of Gauss theorem of gravitation field by analogy,
and of which the earth is approximately regarded as a celestial body with spherical symmetry of mass distribution.
According to the density distribution model of the earth,we fit and calculate the pressure in the earth’s interior
by means of the MATHEMATICA software. It provides a new thinking and way to study the pressure in the
Earth’s interior. Finally,we analyze and discussed the error sources in approximate calculations.
