Abstract: This paper introduces the structure and physical property of, natural gas hydrate (NGH).The hydrate has its special clathrate structure.The new method of transporting natural gas using hydrate has its own advantages, such as safe, dependable, low expenses.Therefore, the research on it has been the hot point of the energy exploring in the world.Also, applying the technology of NGH to natural gas transporting is becoming one of the focuses.The article considers that NGH can be stored and transported on a big scale in a steady state without cooling to a equilibrium temperature except an adiabatical condition
