This invention aims at providing a catalyst body exhibiting a lower degradation of a catalyst due to thermal durability and capable of keeping higher catalyst performance for a long time. A catalyst component such as Pt is directly supported by Zr, W, etc, replacing elements inside a support such as Al of cordierite to provide a catalyst body without forming a coating layer. A combination of the catalyst component and the element inside the support is selected so that support strength is greater than 5 eV by simulation using a density functional method. Coarsening of catalyst particles can be suppressed and a high-performance catalyst body excellent in thermal durability can be obtained.

The invention relates to a terahertz metamaterial chip hydrogel functionalization method. The method comprises the steps that amino or other active functional groups are introduced to the surface of asubstrate of a terahertz metamaterial chip to achieve preprocessing, then, the surface of the preprocessed terahertz metamaterial chip is coated with a prepolymer monomer solution, a prepolymer filmis formed, and finally hydrogel functionalization of the terahertz metamaterial chip is achieved through a polymerization reaction. The intensive absorption characteristic of the THz waveband of waterand the water content changing characteristic in the response hydrogel and target molecule characteristic reaction process are ingeniously combined, and the target molecule special sensing problem inthe liquid phase environment is converted into high-sensitivity detection for the surface modified response hydrogel layer water content through the THz metamaterial technology. Meanwhile, the functionalization modification method is good in universality, simple, convenient to implement, rapid, high in nonspecific adsorption resistance and high in biocompatibility.

The invention discloses a method for preparing functional reconstituted tobacco leaves by virtue of pomace. The method comprises the following steps: extracting tobacco stem and tobacco leaf wastes in hot water, removing impurities in an extracting solution and concentrating the extracting solution, so that a concentrated solution is obtained, and pulping residues obtained from the extraction so as to obtain a tobacco pulp; defibering and decomposing the pomace so as to obtain a fiber pulp; then, conducting screening, removing impurities, conducting dehydrating and concentrating, and conducting fractionated defibering and milling so as to obtain a pomace pulp; conducting medium-consistency refining on softwood pulp so as to obtain an outer fiber pulp; mixing, defibering and dispersing the tobacco pulp, the pomace pulp and the outer fiber pulp, regulating concentration and manufacturing a substrate with a mixed pulp online; and smearing the concentrated solution to the manufactured substrate, and conducting drying and slicing so as to obtain the functional reconstituted tobacco leaves. According to the method disclosed by the invention, by preparing the functional reconstituted tobacco leaves through the full use of the pomace, a filling performance is improved and a tar release amount is reduced, and meanwhile, the finished product (the functional reconstituted tobacco leaves) has a special fruity flavor; raw material production cost is effectively reduced and a wider profit margin is provided to enterprises; and meanwhile, resource waste is relieved and natural environment is protected.

The invention relates to a quantitative calculation method for lake wetland ecological water requirement in an arid region. The method includes determining indicator species, searching for key restraining factors, building a model and calculating the lake wetland ecological water requirement. Compared with a water quantity balancing method, a curve relevant method, a minimum water level method and the like in the prior art, the method achieves the effect that structure and stability of an ecological system in the arid region are comprehensively considered. Compared with a functional method, the method achieves the effect that hydrological condition required by the indicator species around the lake wetland for growth and propagation is considered and is suitable for the lake wetland in the arid region. The method can be directly used for determining an ecological restoring target of the lake wetland in the arid region, guiding the implementation of wetland ecological water supplementation measures and has an important theoretical and practical meaning for basin water resource planning and configuration.

An object of the present invention is to provide an industrially advantageous method for producing a functional organic component and a ceramic component complex at one go based on a concept different from conventional ones. The water-based slurry (C) containing the functional organic component (A) and the ceramic component (B) is supplied into the tank of the spray drying device in the state of fine droplets, and hot air is blown into the tank, so that the The liquid droplets are dried and pulverized when they come into contact with hot air in the tank, so that a finely powdered mixture in which the organic component (A) and the ceramic component (B) are mixed is obtained at one go.
