  Pauli-Blocking effect on the kinetic term is investigated by employing the
quark cluster model. The effect can be understood by the change of the degrees
of the mixing between the incoming wave and the 0$\ell$ state of the
inter-cluster wave function, which can be expressed by a potential which is
highly nonlocal. We look into the properties of this effect by comparing
equivalent local potentials. In the channel where the Pauli-blocking effect is
small, the on-shell equivalent local potential simulates the nonlocal potential
well even for the off-shell behavior. On the other hand, the off-shell behavior
is very different from the original one where the effect is large. This
off-shell behavior, however, can well be simulated by considering the nonlocal
matrix elements only between the $0s$ state and the other states. The energy
dependent potentials are also constructed and found to be helpful to understand
the energy dependence of the effect.
