摘要： The present invention relates to an optical fiber having a large positive dispersion in a wavelength band of 1.55 &mgr;m in order to compensate for a negative dispersion inherent in an NZ-DSF in the wavelength band of 1.55 &mgr;m. This optical fiber comprises a depressed cladding structure constituted by a core region; an inner cladding, provided on the outer periphery of the core region, having a lower refractive index; and an outer cladding having a higher refractive index. In this optical fiber, the relative refractive index difference of the core region with respect to the outer cladding is 0.30% or more but 0.50% or less, and the relative refractive index difference of the inner cladding with respect to the outer cladding is −0.50% or more but −0.02% or less. Also, the optical fiber has a dispersion greater than 18 ps/nm/km at a wavelength of 1.55 &mgr;m, and an effective area of 70 &mgr;m2 or more at the wavelength of 1.55 &mgr;m.

摘要： When a bituminous emulsion is added to a water-containing sludge, the sludge is instantaneously separated into an aqueous layer and a solid layer. But, heavy metals other poisonous pollutants cannot be removed from the separated aqueous layer. In contrast, when a sulfur compound or colloidal sulfur is added to such sludge in combination with a bituminous emulsion, heavy metals and other poisonous pollutants are converted to water-insoluble or hardly soluble sulfur compounds and they are readily removed from the separated water layer. When an inorganic coagulant or organic polymeric coagulant is added in combination, the coagulating and solidifying effects can be further increased. Moreover, the heavy metals and other pollutants fixed in the solid layer are hardly dissolved out and therefore, the separated solid cakes can be used for reclaiming or as water shielding walls.
