摘要：

Models describing the incomplete devil's staircase in betaine calcium chloride dihydrate are briefly discussed. Experimental facts in favour of one or two condensed soft modes are pointed out. Phasons and amplitudons in a structure modulated by two incommensurate waves with the same wavevector are analyzed. Dielectric relaxation in the incommensurate phase between two lock-in improper ferroelectric phases is discussed. © 1991, Taylor & Francis Group, LLC. All rights reserved.
