We exanaine spin-Peierls states in the presence of' spin defects for CuGeO3 wluere tnagtaeticions Ctr" are replaced by non-tnagnetic otaes Zn". Based on the actiora f'or the bosonizedHarniltonian, the state is investigated by trsing patla integral unetltod. Tlae teraaperattrre of spinPeierls transition Tap and, the spin gap arud the uaaagnittrde of the averaged lattice ditauerizationin the grotrnd state haxve loeen calctrlated as a fttnction of doping. Froun comparison of the presentT5?p with the experimental resttlt, 21 good agreeraaent is obtained for the transition teuaaperatttreof Ctru ,5ZIl.5G(203 in the region of' the doping rate, 75< 0.02.
