中文摘要	There are very obvious common features in the electron diffraction patterns of the lambda and tau( mu) phases in the Al - Cr - Si system. The positions of the strong reflections and their intensity distributions are similar for the two structures. The relation of the reciprocal lattices of the lambda and tau( mu) phases is studied. By applying the strong- reflections approach, the structure factors of tau( mu) are deduced from the corresponding structure factors of the known lambda phase. Rules for selecting reflections for the strong- reflections approach are described. Similar to that of lambda, the structure of tau( mu) contains six layers stacked along the c axis in each unit cell. There are 752 atoms in each unit cell, 53 of them are unique. The corresponding composition of the tau( mu) model is Al-3.82 (- x) CrSix. Simulated electron diffraction patterns from the structure model are in good agreement with the experimental ones. The arrangement of interpenetrated icosahedral clusters in the tau( mu) phase is discussed.
