Cellulose macrofibers (MFs) are gaining increasing interest as natural and biodegradable alternatives to fossil-derived polymers for both structural and functional applications. However, simultaneously achieving their exceptional mechanical performance and desired functionality is challenging and requires complex processing. Here, we reported a one-step approach using a tension-assisted twisting (TAT) technique for MF fabrication from bacterial cellulose (BC). The TAT stretches and aligns BC nanofibers pre-arranged in hydrogel tubes to form MFs with compactly assembled structures and enhanced hydrogen bonding among neighboring nanofibers. The as-prepared BC MFs exhibited a very high tensile strength of 1 057 MPa and exceptional lifting capacity (over 340 000 when normalized by their own weight). Moreover, due to the volume expansion of BC nanofibers upon water exposure, BC MFs quickly harvested energy from environmental moisture to untwist the bundled networks, thus generating a torsional spinning with a peak rotation speed of 884 r/(min·m). The demonstrated rapid and intense actuation response makes the MFs ideal candidates for diverse humidity-response-based applications beyond advanced actuators, remote rain indicators, intelligent switches, and smart curtains.

Query translation mining is a key technique in cross-language information retrieval and machine translation knowl-edge acquisition. For better performance, the queries are classified into transliterated words and non-transliterated words based on transliterated word identification model, and are further channeled to different mining processes. This paper is a pilot study on query classification for better translation mining performance, which is based on supervised classification and linguistic heuristics. The person name identification gets a precision of over 97%. Transliterated word translation mining shows satisfactory performance.

马克思“美好生活”观及其中国意义

中共中央党校（国家行政学院）学报 2021年第4期25卷 64-70页

作者：周梅玲湖南大学马克思主义学院长沙岳麓410082

在马克思的哲学视域中,“美好生活”是指现实的人在生产力充分发展、社会交往普遍建立的基础上,利用自由时间进行自觉劳动,以实现个性的丰富和才能的全面发展,进而达到每个人自由发展的普遍状态,它涉及生产力、社会交往、自由时间、自... 详细信息

在马克思的哲学视域中,“美好生活”是指现实的人在生产力充分发展、社会交往普遍建立的基础上,利用自由时间进行自觉劳动,以实现个性的丰富和才能的全面发展,进而达到每个人自由发展的普遍状态,它涉及生产力、社会交往、自由时间、自觉劳动等诸多要素。共产主义社会即承载人类美好生活的最终社会形态,只有在共产主义社会中,才能呈现出人与自身、人与人、人与自然、人与社会等多层关系和不同样态的和谐与统一。然而,实现共产主义美好生活是一个长期的历史过程,需要经历人类社会发展的三大历史阶段才能最终实现。社会主义是共产主义的初级阶段,新时代美好生活与共产主义美好生活具有内在一致性,马克思揭示的美好生活图景对于我们解决新时代美好生活问题具有重要启示意义。

本文运用数据库技术对四套语文教材中汉字结构认定的笔顺、笔画名称、独体字合体字等三种现象进行统计分析,参照相关国家语言文字规范标准作对比分析。结果表明:教材中汉字结构整体落实情况大致符合国家语言文字规范标准,但也存在着混乱和分歧,某些教材的笔顺和笔画名称存在不规范和不统一的现象,各套教材独体字和合体字的确定也存在差异。这表明我国的语文教材规范化还略显滞后,国家语言文字规范标准还需要进一步全面落实到语文教材的建设之中。
