ABSTRACT:
A method of storing voltile substances comprises cooling the substances, and maintaining the saturated vapor pressure of the substances to not higher than normal pressure. A container for storing liquid helium comprises means for blocking a superfluid surface flow of liquid helium where the means is provided on an inner wall or our wall of the container. A method of controlling a surface flow of superfluid helium comprises controlling the surface flow by bringing at least a part of the surface of a structure into a state in which the surface passage is suppressed. The surface flow of superfluid helium is caused on the structure.
