Abstract：
The on shell and the off shell formulisms of the gluon propagators in a system of confined quarks and gluons are discussed, and the components of sea quarks found in a proton are calculated on the basis of the static spherical cavity approximation of MIT bag model. It is shown that the off shell results are obviously smaller than those of the on shell approximation.
