A mechanism which may be responsible for the anomalies in the behaviour of type II ferroelectrics near the lock-in transition is considered. The state of the system is suggested to be quasistationary. The defects of the incommensurate modulation wave are found to play an important role and give additional contributions to the thermodynamic characteristics of the system.
