The invention relates to a method for enhancing bituminous mixtures by adopting chopped basalt fibers, belonging to the technical field of novel compound materials. According to the invention, continuous basalt protofilaments or twistless rovings the surfaces of which are expanded into fibers in certain length, and then the fibers are used for enhancing the bituminous mixtures in a certain doping proportion and can be respectively used for maintaining the bituminous mixtures used for new construction and reconstruction and extension of highways and SMA and OGFC bituminous mixtures as well as fiber seals. In addition, the fibers can also be used for the enhancement of high-speed railway packing layer CA mortar and relevant hydraulic architectures. The chopped basalt fiber plays roles of enhancing, toughening and elasticizing the cracking prevention, crack resistance and reinforcement and 'bridging' in the enhanced bituminous mixtures, can obviously increase the anti-rutting ability of highways of the enhanced bituminous mixtures and reduces the whole life costs of the enhanced bituminous mixtures; if the fibers are used for high-speed railway plate-type ballastless tracks and CA mortar, the bending strength and the deformation resistance can be increased, i.e. the fibers play a role of crack prevention and crack resistance; in addition, the fibers have better anti-water leakage action if being used for Hydraulic and Hydro-Power Engineering.

The dielectric device includes a substrate, a lower electrode, a dielectric layer, and an upper electrode. The lower electrode is bonded onto the substrate. The dielectric layer is bonded onto the lower electrode. The dielectric layer is obtained through thermal treatment of a film layer formed by spraying of a powdery dielectric material and a fine-particulate metal. In the thus-formed film layer, the metal is dispersed in the matrix of the dielectric material. Thermal treatment of the film layer causes migration of the metal in the film layer. This metal migration causes a lower-electrode-adjacent portion and upper-surface-adjacent portion of the dielectric layer to have different metal contents.
