摘要：

Some properties of betaine compounds are reviewed mostly from a phenomenological p o i n t o f view. Order parameters of various phase transitions, related changes of symmetries, anomal i e s of macroscopic properties, spontaneous quantities and domains are discussed. A two-soft-mode model i s proposed for description of peculiar properties of betaine calcium chloride dihydrate. © 1990, Taylor & Francis Group, LLC. All rights reserved.
