Abstract: In this paper,the effects of temperature and liquid volume fraction on pressure rise in non-loss cryogenic vessels are analyzed. Graphs are provided for the relation between environmental temperature and the performance of non-loss storage for the different types of cryogenic vessel(multi-layer insulation, vacuum-powders insulation, high-vacuum insulation), as well as for the relationship between storage-pressure and heat flow received by the container per unit volume for various volume fractions.The conception of optimum liquid volume fraction is also presented .The results are useful for the design,use and choice of non-loss storage vessels for liquefied gases, precious gases,rare gases and poisonous gases.
