The novel bimetallic Sn-Im/Al2O3 catalysts prepared by three methods for NO reduction by propene were investigated. The results showed that the catalytic activity was enhanced significantly in the presence of H2O on sol-gel catalyst, and the maximum NO conversion increased from 46% to 92%, even in the presence of 100 ppm SO2, NO conversion was still 80%.

The thermal effect and the heat generation in diode-end-pumped continuous-wave 914-nm Nd：YVO4 lasers are investigated in detail. A theoretical model of a diode end-pumped solid-state laser is constructed to analyse the influence of fractional thermal loading on the thermal effect in the Nd：YVO4 laser based on finite element analysis. The thermal focal lengths and the end-surface deformations of laser rods in Nd：YVO4 quasi-three-level and four-level lasers are measured and compared with the results obtained by ordinary interferometry for the demonstration of higher thermal loading in 914-nm laser. Finally the fractional thermal loading in the Nd：YVO4 quasi-three-level laser is calculated by matching the experimental and the simulated end deformations.

It is a key problem to accurately calculate beam spots＇ center of measuring the warp by using a collimated laser. A new method, named double geometrical center method （DGCM）, is put forward for the first time. In this method, a plane wave perpendicularly irradiates an aperture stop, and a charge couple device （CCD） is employed to receive the diffraction-beam spots, then the geometrical centers of the fast and the second diffraction-beam spots are calculated respectively, and their mean value is regarded as the center of datum beam. In face of such adverse instances as laser intension distributing defectively, part of the image being saturated, this method can still work well. What＇s more, this method can detect whether an unacceptable error exits in the courses of image receiving, processing and calculating. The experimental results indicate the precision of this method is high.

The submicron chromium dioxide（CrO2） thin film was fabricated on a poly-crystal titania（TiO2） film using Si wafers as substrates by atmospheric pressure chemical vapor deposition（CVD） method. X-Ray diffraction patterns show that the CrO2 films were pure rutile structure. Scanning electron microscopy（SEM） images indicate that the CrO2 films consisted of submicron grains with a grain size of 250--750 rim. The magnetic researches reveal that the magnetic easy axis is parallel to the films, and at room temperature, the CrO2 films show linear magnetoresistance.

By analyzing the azimuthal variations of total gravitating mass profiles in the central 300 h^-1 71 kpc regions of four galaxy clusters with Chandra data, we find that the azimuthally-averaged mass profiles may have been systematically underestimated by 16^＋9 -8% at lσ significance in the 50-100 h^-1 71 kpc regions, probably due to the prevailing existence of 2-D hot gas substructures in 100-300h^-1 71 kpc. The mass biases become negligible（-7＋11 _9＋ %） at 〉 150 h^-1 71 kpc. We confirm the results that the gas temperature maps can be used to probe the departure from hydrostatic equilibrium and help quantify the systematic biases in X-ray mass measurements in the central regions of clusters.

Objective: To investigate the inhibitory effect of Tanreqing Injection(TRQ) on the activation of nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3(NLRP3) inflammasome in macrophages infected with influenza A virus and the underlying mechanism based on mitophagy pathway. Methods:The inflammatory model of murine macrophage J774A.1 induced by influenza A virus [strain A/Puerto Rico/8/1934(H1N1), PR8] was constructed and treated by TRQ, while the mitochondria-targeted antioxidant Mito-TEMPO and autophagy specific inhibitor 3-methyladenine(3-MA) were used as controls to intensively study the anti-inflammatory mechanism of TRQ based on mitophagy-mitochondrial reactive oxygen species(mt ROS)-NLRP3 inflammasome pathway. The levels of NLRP3, Caspase-1 p20, microtubule-associated protein 1 light chain 3 Ⅱ(LC3Ⅱ) and P62 proteins were measured by Western blot. The release of interleukin-1β(IL-1β) was tested by enzyme linked immunosorbent assay, the mt ROS level was detected by flow cytometry, and the immunofluorescence and co-localization of LC3 and mitochondria were observed under confocal laser scanning microscopy. Results: Similar to the effect of Mito-TEMPO and contrary to the results of 3-MA treatment, TRQ could significantly reduce the expressions of NLRP3, Caspase-1 p20, and autophagy adaptor P62, promote the expression of autophagy marker LC3Ⅱ, enhance the mitochondrial fluorescence intensity, and inhibit the release of mt ROS and IL-1β(all P<0.01).Moreover, LC3 was co-localized with mitochondria, confirming the type of mitophagy. Conclusion: TRQ could reduce the level of mt ROS by promoting mitophagy in macrophages infected with influenza A virus, thus inhibiting the activation of NLRP3 inflammasome and the release of IL-1β, and attenuating the inflammatory response.

少数民族是国家的重要组成部分,少数民族民众和其他民众一样享有同等的法律权利,其正当权益受到法律保护,这一点在体育领域中也不例外。随着民族体育的外部推广发展和民族民众对国家体育活动的更多参与,体育领域中的民族色彩愈发突出。刑法对体育的深入规制是体育事业发展的必然选择,鉴于体育领域逐渐突出的民族色彩,体育的刑法规制必然要有所应对,在刑法规则中突出民族意识。有关体育刑法的民族意识突出主要表现在刑法对民族体育规则的定性、刑法对民族体育未来发展的推动、刑法对民族民众体育权益的保护等。
