摘　　要：The effect of slow neutron irradiation at a low Auence of about 10^(8)n/cm^(2) on the microstructures of Bi-2223 polycrystalline samples was observed by transmission electron microscopy.By comparative study of the defect structures in a given area in one sample,we get evidence for the flux pinning enhancement by low Auence slow neutron irradiation.
