摘要：

It is found that the hydrates obtained by reaction of liquid water with a hydrate-forming gas have a cellular structure with a cell ∼10-5 cm in size. At T ∼ 274 K, the thickness of the walls of the methane hydrate cell is ∼10-7 cm. Formation of the cellular structure is due to a competition between the bulk (difference between chemical potentials, specific energy of elastic deformation) and surface energies. At positive temperatures, monolithic methane hydrate is formed at pressures higher than 6 MPa.
