摘　　要：对准一维Ⅶ-Ⅷ族变价化合物低温畸变超晶格，采用计算机投影寻踪回归模拟技术，对由位 移变换和ＨＦ平均场近似方法得到的多维序参量积分方程组，进行投影寻踪回归模拟，得到了系统的超晶格 －正常态转变相图和序参量变化关系．The superlattice distortion of quasi-one-dimentional Ⅶ-Ⅷ transition-metal complexes under low temperature has been studied by means of computer projecton simulation technique based on the multi-dimensional order parameter integral equation set obtained by a displacement transformation and HF mean field approximation. The phase diagram and the change relations between order parameters of the system are gained.
