摘要：
The paper studies metastable phases of 4,4'-di-n-heptyloxyazoxybenzene ( liquid crystal substance) using adiabatic calorimetry. The process of transformation between metastable and stable phases is described quantitatively. The conclusion concerns activation energies for metastable phase to stable phase transition.
