在联合国教科文组织《保护非物质文化遗产公约》等国际公约和中国非遗保护法规文件精神指导下,20年来中国非遗保护工作取得了巨大成就。国际公约与国内法及相关文件有着不同的逻辑走向,前者强调尊重文化多样性、社区主体性及其创造性,后者重视统一性、民族主体性与传统性。中国非遗保护实践的特色在于:国家主导的系统性保护格局与相关制度创新,社会全面参与的中华文化传承,意识形态与价值观逐步增强的“非遗的人民性”。基于非遗保护的历史与经验,未来的中国非遗保护实践需注重以下几个方面:政府主导应该抓关键与重点;鼓励社区民众的文化创造与族际的文化交流与共享;处理好非遗保护传承过程中的道、艺、器三者之间的关系;促进非遗保护传承工作全面融入国民教育体系等。

In this article,the authors introduce the concept of shadowable points for set-valued dynamical systems,the pointwise version of the shadowing property,and prove that a set-valued dynamical system has the shadowing property iff every point in the phase space is shadowable;every chain transitive set-valued dynamical system has either the shadowing property or no shadowable points;and for a set-valued dynamical system there exists a shadowable point iff there exists a minimal shadowable *** the end,it is proved that a set-valued dynamical system with the shadowing property is totally transitive iff it is mixing and iff it has the specification property.

After 900 ℃ high-vacuum annealing and air cooling, a special band was observed in pure titanium. Energy-dispersive spectrum showed that the composition of the band and the matrix is the same. By tilting the band to different zone axes and taking selected-area electron diffraction (SAED) patterns, we found that the structure of the band is distorted face-centered cubic (fcc) with the lattice constants a, b, and c deviating slightly from each other on the basis of the analyses of the SAED patterns together with the tilting angles. The lattice constants a, b, and c are calculated based on the measurement of interplanar spacing according to high-resolution transmission electron microscopy (HRTEM) images. The orientation relation between the hexagonal-close-packed (hcp) matrix and the distorted fcc band is [11(2)0]hcp//[110]fcc and (0001)hcp//(1(1)1)fcc according to SAED analysis. The phase boundary between the matrix and the band was observed to demonstrate serrated configuration composed of two kinds of micro-steps: ((1)11)//(0002) and ((1)11)//(10(1)1) on the basis of Cs-corrected HRTEM characterization. The distorted fcc band is deduced to be a thermal-induced metastable phase transformed from the high-temperature body-centered cubic (bcc) structure during the allotropic transformation from bcc to hcp based on orientation relation analysis.

Developing an effective method for improving the reproducibility of positive temperature coefficient(PTC)effect is of great significance for large-scale application of polymer based PTC composites,owing to its contribution to the security and ***,we developed a carbon black(CB)/high density polyethylene(HDPE)/poly(vinylidene fluoride)(PVDF)composite with outstanding PTC reproducibility,by incorporating 1-octyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide([OMIm][NTf2])into the *** multiple repeated temperature cycles,the PTC performance of as-prepared material keeps almost unchanged and the varition of resistance at room temperature is less than 7%.Our studies revealed that[OMIm][NTf2]contributes to the improvement of PTC reproducibility in two ways:(i)it acts as an efficient plasticizer for refining the co-continuous phase morphology of HDPE/PVDE blends;(ii)it inhibits the crystallization of PVDF through the dilution effect,leading to more overlaps of the volume shrinkage process of HDPE and PVDF melt which results in the decrease of interface gap between HDPE and *** study demonstrated that ionic liquids as the multifunctional agents have great potential for improving the reproducibility in the application of the binary polymer based PTC composites.

食品中农药残留超标对生物多样性以及人类健康造成潜在威胁。固相萃取技术广泛应用于农药的萃取,该方法的核心是吸附材料的选择。共价有机骨架(COFs)材料因其独特的优点在样品预处理中得到广泛的关注,而COFs的结构决定了材料的吸附性能,这对提高农药的萃取效果有重要作用。该研究制备了6种不同结构与性质的COFs(同一母体接枝不同官能团、具有不同带电性质、具有不同共轭结构),在不改变COFs结构的情况下,将其制备为COFs-海藻酸钠水凝胶(CACPs),建立了CACPs-分散固相萃取(CACPs-dSPE)方法,比较不同CACPs对氨基甲酸酯类、三唑类以及三嗪类农药的萃取效果。利用扫描电子显微镜、傅里叶变换红外光谱、X射线晶体衍射等方法对系列COFs以及系列CACPs的形貌、结构与性质进行表征。CACPs-dSPE结合高效液相色谱(HPLC)或紫外-可见分光光度法(UV-Vis)探究萃取效果,并结合理论计算模拟COFs与待测物的结合情况,探讨了不同CACPs对氨基甲酸酯类、三唑类以及三嗪类农药的吸附机理。结果表明:CACPs对不同类型农药的吸附性能是由其多孔结构性质(比表面积、孔径大小)和所负载COFs的固有结构协调决定,大的共轭结构、接枝羟基基团的COFs所制备的CACPs最有利吸附三类农药,其中Dt-TAPB-CACPs的萃取效果最佳。这为萃取农药过程中吸附材料的选择和设计提供了理论指导。

To improve the design speed and reduce the design cost for the previous blade design method, a modified inverse design method is presented. In the new method, after a series of physical and mathematical simplifications, a sail?like constrained area is proposed, which can be used to configure di erent runner blade shapes. Then, the new method is applied to redesign and optimize the runner blade of the scale core component of the 1400?MW canned nuclear coolant pump in an established multi?optimization system compromising the Computational Fluid Dynamics(CFD) analysis, the Response Surface Methodology(RSM) and the Non?dominated Sorting Genetic Algorithm?II(NSGA?II). After the execution of the optimization procedure, three optimal samples were ultimately obtained. Then, through comparative analysis using the target runner blade, it was found that the maximum e ciency improvement reached 1.6%, while the head improvement was about 10%. Overall, a promising runner blade inverse design method which will benefit the hydraulic design of the mixed?flow pump has been proposed.

Sumoylation is an important protein modification discovered recently. SUMO（small ubiquitin-related modifier） pathway regulates the protein stability and transcriptional activity with a 12-kDa small molecular protein, SUMO, ligated to the target protein. The purification of SUMO proteins is a key step to reveal their function. The purpose of this study was to construct the recombinant SUMO1 gene cloned to a pGEX-4T-1 vector to express and purify the SUMO1-GST fusion protein in Escherichia coli. First, the full length DNA sequence of SUMO1 gene was amplified by PCR and was ligated to pMD18-T vector. Then the SUMO1 gene was subcloned to pGEX-4T-1 prokaryotic expression vector between BamHI and XhoI sites, and transformed in Escherichia coli DH5α cells. The right colonies were identified by restrictive enzyme digestion and sequencing. The correct rebombinant plasmid of pGEX-4T-1-SUMO1 was transformed in Escherichia coli BL21 cells and then induced by IPTG（isopropyl- β-D-1- thiogalacto-pyranoside） to express the SUMO1-GST fusion protein. The highly purified SUMO1-GST（glutathione S-transferase） fusion protein was obtained by affinity chromatography. Finally, the properties of SUMO1-GST fusion protein were confirmed by Coomassie brilliant blue strain and Western blot analysis. The recombinant plasmid of pGEX-4T-1-SUMO1 was successfully constructed, and SUMO1-GST fusion proteins were successfully expressed.
