Equilibrium velocity distribution of low-energy particles in spherically   symmetric gravitational field
  Based on Einstein's theory of gravitation, we discuss the influence of a spherically symmetric gravitational field on Maxwell's law of velocity distribution. We derive the equilibrium velocity distribution of low-energy particles in the spherically symmetric gravitational field and calculate the escape rate of low-energy particles in a container with a leak placed in the spherically symmetric gravitational field. They can serve as the tests of Einstein's theory of gravitation.
