Abstract: A plasma-assisted annealing system includes a high temperature furnace, a plasma-induced dissociator and a connecting duct. The plasma-induced dissociator is provided to dissociate a working gas and exhaust the dissociated working gas from its working gas outlet. Both ends of the connecting duct are connected to the working gas outlet of the plasma-induced dissociator and a gas inlet of the high temperature furnace, respectively. The working gas dissociated in the plasma-induced dissociator is introduced into the high temperature furnace via the connecting duct.

Abstract: Provided are a preparation method for a propylene epoxidation catalyst, and a use thereof. During the preparation, an alkoxide solution of a prepared active component and a silica gel support are mixed, then a rotary evaporation treatment is performed on the mixture to remove a low-carbon alcohol to obtain a catalyst precursor, and then the obtained catalyst precursor is subjected to calcination and silylation treatments to obtain the propylene epoxidation catalyst. The catalyst is prepared in a simple process, can be applied to the chemical process of preparing propylene oxide by propylene epoxidation, has high average selectivity to propylene oxide, and has industrial application prospect.

Abstract: A method for calculating a bending moment resistance of an internal unbonded post-tensioned composite beam with corrugated steel webs (CSWs) and a double-concrete-filled steel tube (CFST)lower flange includes: determining a degradation law of sectional flexural rigidity of the internal unbonded post-tensioned composite beam with CSWs and a double-CFST lower flange based on numerical analysis, and establishing a sectional flexural rigidity degradation model of the composite beam. The method can include segmenting a bending moment diagram of the composite beam based on the sectional flexural rigidity degradation model, and establishing a segmented integral equation of IUPS strain increment. The method can include establishing an equilibrium equation of force and a bending moment by considering contributions of concrete, the steel tubes, the upper steel flange, the IUPSs, and reinforcement in the composite beam.
