Pinned particles in space are introduced in our
molecular-dynamics simulations. Effects of pinned particles on the
structural relaxation in binary soft-sphere supercooled liquids
are examined. It is found that the relaxation dynamics becomes
slower as the number of the pinned particles increase and this
tendency is enhanced as the degree of supercooling becomes high.
In addition, we obtained the temperature dependence of the size
ξ of the cooperatively rearranging region as power law 
from our simulations.
