we only cover its simplest aspects. For example, we only concern ourselves with
nucleation of incipient gas hydrates, that is, nucleation of gas hydrate from a
hydrate-free state, and do not touch any secondary nucleation, that is, nucleation of
a second type of gas hydrate in the presence of a hydrate phase. A short tea break
topic is inserted at the end of each chapter. An appendix is added at the end of the
monograph that lists nucleation rate data of clathrate hydrates of some guest gases.
