With the goal of improving processability of imide oligomers and achieving high toughness of thermosetting polyimides, a series of 4-phenylethynylphthalic anhydride（PEPA）-terminated imide oligomers prepared by the reaction of 2,3,3＇,4＇-diphenyl ether tetracarboxylic acid dianhydride（a-ODPA） and 3,4＇-oxydianiline（3,4＇-ODA） with different molecular weights（degree of polymerization： n = 1？9） were formed. The resultant oligomers with different molecular weights were characterized for their chemical architecture, cure behavior, thermal properties, solubility in organic solvents and rheological characteristics. Besides, the thermal properties and tensile test of cured polyimide films were also evaluated. The imide oligomer（degree of polymerization： n = 1） has some somewhat crystalline phase, and imide oligomers（degree of polymerization： n = 2？9） showed excellent solubility（40 wt%） in N-methyl-2-pyrrolidone（NMP） and N,Ndimethylacetamide（DMAc） at room temperature. Furthermore, the rheological properties of imide oligomers showed very low melt viscosity and wider processing window. The cured films exhibited good thermal properties with the glass transition temperatures of 282？373 ？C and 5 wt% thermal decomposition temperatures higher than 551 ？C in nitrogen atmosphere. The elongation at break of the prepared films was found to be high（almost 〉 9.3%）.

With the development of IoT and 5G technologies,more and more online resources are presented in trendy multimodal data forms over the Internet.Hence,effectively processing multimodal information is significant to the development of various online applications,including e-learning and digital health,to just name a few.However,most AI-driven systems or models can only handle limited forms of information.In this study,we investigate the correlation between natural language processing(NLP)and pattern recognition,trying to apply the mainstream approaches and models used in the computer vision(CV)to the task of NLP.Based on two different Twitter datasets,we propose a convolutional neural network based model to interpret the content of short text with different goals and application backgrounds.The experiments have demonstrated that our proposed model shows fairly competitive performance compared to the mainstream recurrent neural network based NLP models such as bidirectional long short-term memory(Bi-LSTM)and bidirectional gate recurrent unit(Bi-GRU).Moreover,the experimental results also demonstrate that the proposed model can precisely locate the key information in the given text.

当前成人在线教学的教师没有明确转换教师角色与任务,常常只是将传统课堂搬迁到网络上,在线主体的心理距离因时空分离不断扩大,教师对在线教学的认知、行为与情感投入不够,强烈影响了学员的学习投入感、师生疏离感与教学成效。从远程教育学看,成人远程教育的关键是设计优秀在线课程并提供学习支持服务以实现三种交互,所以,成教的直播课、录播课、仿真技能课的有效实施都需利用对应的社交平台与工具平台设计课前课中课后的支持服务,依据布鲁姆教学目标的分类区别化设计成人在线教学策略,根据内容特征与学员情感需要设计多种混合式教学,利用平台记录的学习大数据及其画像,从交互距离与远程学员自治两个维度让师生获得动态、整全的及时诊断与警示。

A free-standing superhydrophobic film is prepared by sequentially dip-coating a commercially available filter paper with nano SiO2 suspension, epoxy emulsion, and octyltrimethoxysilane solution. A surface with micro- or nano-roughness is formed because SiO2 nanoparticles are uniformly and firmly adhered on the backbone of the filter paper by the cured epoxy resin. Furthermore, the surface energy is significantly reduced because of introducing octytrimethoxysilane. Such a surface structure makes the prepared film a superhydrophobic material. Due to its free-standing nature, this superhydrophobic film can be used to remove water from turbine oil by filtration. The efficiency of water removal is high (up to 94.1%), and the filtration process is driven solely by gravity without extra energy consumption. Because of the facile fabrication process and the high efficiency of water removal, this free-standing superhydrophobic film may find application in power industry.

The teaching abilities of bilingual teachers have emerged as one of the major bottlenecks hindering the further development of Chinese-foreign cooperative education projects.Implementing the JiTT(Just-in-Time Teaching)model in bilingual courses of Chinese-foreign cooperative education can effectively integrate information technology with traditional classroom teaching.This integration enhances teaching quality and effectiveness,encourages university instructors to improve their diverse and collective capabilities,promotes digital development,and contributes to the enhancement of students’learning abilities and overall improvement.

In the context of the internationalization of higher education,many non-English speaking countries,from Europe to Asia,are promoting English as a medium of instruction(EMI).The EMI in South Korea started earlier and developed rapidly under the promotion.From the initial“Study Abroad in Korea Plan”to the World Class University(WCU)and Brain Korea 21st century(BK21)PLUS programs,with the support and guidance of the government,South Korea’s higher education has made significant progress,with the global top 100 universities in QS increasing from 1 to 6 in South Korea.

ZnO nanoneedle/nanocolumn （NN/NC） composite films were grown via reactive electron beam evaporation （REBE） in the NH3/H2 gaseous mixture by using polycrystalline ZnO ceramic targets as source materials. The growth was performed at low substrate temperatures （450～500℃） without employing any metallic catalysts. As-prepared samples were then rapidly annealed in 02 ambient at a higher temperature （600℃）. Electron microscopic observations revealed the typical composite-structured morphologies of NN/NC/substrate of ZnO nanomaterials grown at 500℃. Such unique morphologies should render potential applications, for instance, as an efficient microwave absorption material utilized in the fabrication of concealed aerostat. In addition, X-ray diffraction and photoluminescence measurements showed remarkable improvement in crystal and optical qualities of ZnO NN/NC composite films after annealing.

20世纪90年代,舞蹈学界开展了“全国民族舞蹈创作研讨”,对于“民族舞蹈”的创作研讨,迄今为止,它是“空前绝后”的。在这次“研讨会”之后,作为“作品形态”的少数民族的民间舞“晚会”创作开始发力了。其中,门文元创作的土家族的《土里巴人》以“编织一种文化,推出一个民族”的理念,将“作品形态”的中国民间舞创作、特别是少数民族舞蹈创作推向了一个新的高度。进入21世纪,杨丽萍再爆“华彩”,她创作的《云南映象》《藏谜》《云南的响声》“三部曲”,成为21世纪头十年中国民间舞“作品形态”高耸的丰碑。在《云南的响声》的创作过程中,杨丽萍“鼓励演员们在保持地方、民族特色的同时不必拘泥于固有的原生态”,这正是原生态民间舞得以自然传承、发展的精义所在,是对舞蹈学者傅兆先所谓“创又保”式民间舞发展理念的实践性呈现,也是中国民间舞作品形态之“创作的意识”的水到渠成、瓜熟蒂落。

党的二十大指出,要扎实推进共同富裕。从法学视角来看,共同富裕具有法治文明意义。作为治国之策的共同富裕古已有之,从传统富民观,到“平均地权”说,再到新时代共同富裕,共同富裕的理论伴随着权利保障理念而萌生、明晰与丰富。以法思想言之,共同富裕与以人民为中心的习近平法治思想相统一;以法制度言之,它与宪法的社会主义法治原则的核心内涵相契合;以法哲学言之,它的法权要求与中国式法治现代化相呼应,推进共同富裕将丰富中国式法治现代化的价值内蕴。与此同时,中国式法治现代化是推进新时代共同富裕的重要保障,为此,应做好与脱贫攻坚法治建设的衔接,构建更为全面的分配正义制度体系,着力强化法律制度的贯彻实施。
