摘要：

Enhancements of spin correlation functions due to nonmagnetic impurities are investigated by both diagonalization method and a quantum Monte Carlo method. Spacial distributions of spin correlation functions near impurities are obtained where large enhancements are observed. On the other hand, correlations between large separated spins seem to be reduced by impurities.
