摘要：

The microstructure of PbZr0.9Ti0.1O3 ceramics is studied by transmission electron microscopy. Two types of domain patterns are found, namely, the 109degrees domain with the F spots (1/2{hkl} superlattice reflections) observed in neighboring domains and the 71degrees domain with the F spots observed in one domain and having disappeared in the neighboring one. The computer simulation indicates that the F spots are forbidden at h=k positions so that they do not appear in the electron diffraction pattern if viewed along the [(1) over bar 10] direction. Based on this result, the observed two types of domain patterns and their corresponding diffraction patterns can be explained. (C) 2003 American Institute of Physics.
