摘要:

Commensurate and incommensurate phases are defined, with emphasis on displacive transitions. Methods of describing incommensurate phases, both by space groups in higher dimensions and by representation theory, are given. Points are illustrated by the examples of γ-sodium carbonate, thiourea, the α → β transition in quartz and by magnetic structures.
