• The observation of spin-Peierls transition (at the temperature 'ISP Th 14 K) in the inorganiccornpound CuGeO3 has attracted considerable attention. We investigate characteristic dynanai-cat behaviors of the system accompanied by temperatvxre-dependent lattice displacements fromthe theoretical point of view. In the special case of 1-D XY anti['erromagnets with which thepresent paper mainly concerned, the fernaion representation ?t[[ows rigorous calculations, so thatintrinsic dynamical behaviors of spin-Peierls transition are elttcidated withotnt any approxirna-tion. The generalized susceptibility is calculated by means of the two-time Green fttnctions, Wefind interesting dynarnical properties that will be a cltte to the extensive study on the corre-sponding Heisenberg antiferromagnet.
