摘      要：The 1/2{111}-type ordered structure observed in lanthanum-modified lead zirconate titanate has been proved to be stable in the next-nearest-neighbor approximation by the eightpoint cluster variation *** order parameter as a function of the composition of La3+and lead vacancies and the order-disorder phase diagram have been obtained.
