Abstract: The ordering process of a scalar fluctuating field near the lability boundary of a phase transition of the first kind is considered. It is found that under some conditions a long-term large-scale structure can be formed, which is analogous to the one arising in the critical domain of the first kind phase transition. It is noted that as instability develops, this structure of chains and dense local groups of germs should appear analogous to the ones in real systems. Results are compared with the possibility of fluctuating inductions of continuous phase transitions predicted by other authors in the framework of the thermodynamic renormgroup approach.
