Abstract: A thermal analysis method and apparatus, and a computer program that enable highly accurate heat transfer simulation of a structure or space, while reducing calculation costs. By performing thermal analysis on a structure or space using the calculation meshes generated by initial dividing means, the spatial distribution of heat flux vectors J and temperature gradient vectors ?T are calculated; by calculating the volume integrals of the inner products J·?T of the heat flux vectors J and the temperature gradient vectors ?T for individual partitioned regions and acquiring the absolute values of the volume integrals, thermal management sensitivity indices are calculated for the partitioned regions. Subsequently, partition of calculation meshes and subdivision of partitioned regions are performed on a predetermined number of partitioned regions that indicate greater indices among the calculated thermal management sensitivity indices, for example one partitioned region.

Abstract: There are provided a method for producing a hydrogen gas-containing material in which higher safety than in a production method of the related art is secured and which is simple and has high production efficiency, and a method for producing a hydrogen gas-containing material and a device for producing a hydrogen gas-containing material in which it is possible to prevent nitrogen gas from being mixed into the hydrogen gas-containing material produced by the production method and it is easy to control an amount of hydrogen contained in the hydrogen gas-containing material. As one aspect, there is provided a method for producing a hydrogen gas-containing material including mixing a liquid composition containing a gelling agent or a thickener and a liquid medium with hydrogen gas in a line mixer (20) and cooling the liquid composition containing hydrogen gas in a liquid-transfer pipe (22) connected to the line mixer (20) and causing the liquid composition containing hydrogen gas to gel or thicken.
