摘要：

The matter and the pseudoscalar densities inside a hadron are calculated via gauge-invariant equal-time correlation functions. A comparison is made between the charge and the matter density distributions for the pion, the rho, the nucleon and the Delta(+) within the quenched theory, and with two flavors of dynamical quarks.
