摘要:
A method for reducing the amplitude of vibration and the pressure wave (6) from a radiating surface (5) and/or an incident surface (3) of a material exposed to mechanical and/or acoustic vibration. The material consists of an anisotropically shaped heavy resilient structure with an internal geometry capable of deflecting and localizing vibration (7) within the structure. A specific material may be incorporated into the areas where vibrational energy is localized in order to convert the vibrational energy into another form of energy.
摘要:
The active material is constituted by an alkali metal in the zero valent state which alkali metal is inserted into an insertion compound. The insertion compound receiving the alkali metal has an ordered three-dimensional lattice structure and is constituted by at least one intermetallic compound having polyatomic anionic clusters with atoms chosen from the group constituted by gallium, boron and aluminum, and with structuring counter ions chosen from the group constituted by alkaline earth and alkali ions.
