ABSTRACT
Recent advances in the molecular dynamics simulations of spontaneous nucleation and growth methane hydrate show that an amorphous phase is first reached. However, has not been well described, due to insufficient identification cage structures. Here, we develop a method, called "face-saturated incomplete analysis", which can identify all face-saturated cages given system. As result, it found thousands types abundant occupancy states are present hydrate. Moreover, crystallinity evaluated according quantitative calculation linking structures, critical nucleus also estimated on basis clustering analysis for cages.
