The complexity of online narratives and their important influence on events,attitudes,and emotions in society make visible certain limitations in the explication of such narratives found in traditional narrative *** generative mechanism provides the logical starting point for understanding online *** correlatives,text assemblage and specific texts,as the organic structure of online narratives,shape the intertextual existence and dynamic accumulation of the online text.A universal multidirectional co-construction forms around event correlatives and between specific texts and the pre-text,post-text and synchronous text within the text assemblage,while the textual object,the communicating subject and the online group communication context together build up the interpretive system of online narrative *** generative mechanism and vitality of online narratives not only provide guarantees for the active nature of online communication,but also become a huge variable in social development,profoundly influencing social communication and even our way of thinking.

The lithium dendrite and parasitic reactions are two major challenges for lithium(Li)metal anode—the most promising anode materials for high-energy-density *** this work,both the dendrite and parasitic reactions that occurred between the liquid electrolyte and Li-metal anode could be largely inhibited by regulating the Li+-solvation *** saturated Li+-solvation species exist in commonly used LiPF 6 liquid electrolyte that needs extra energy to desolvation during *** solvation induced high-energy state Li-ions would be more energy favorable during the electron-reduction process,dominating the competition with solvent reduction *** Li-symmetric cells that are cycling at higher temperatures show better performance;the cycled lithium metal anode with metallic lustre and the dendrite-free surface is *** calculation and experimental measurements reveal the existence of high-energy state Li+-solvates species,and their concentration increases with *** study provides insight into the Li+-solvation structure and its electrodeposition characteristics.

A liquid-solid fluidized bed separator, used for the separation of coarse slime, was developed. Test parti- cles sized in the range from 0.25 to 0.5, 0.5 to 1.0, and 0.25 to 1.0 mm were separated in the liquid-solid fluidized bed. Beds with column heights of 1200, 1500, and 1800 mm were tried. The clean coal and the railings were subsequently analyzed by float-sink testing. The results showed that the ash and yield of clean coal both decreased with increasing column height, for all three size fractions, and that the ash of the clean coal obtained from tests on the broader size fraction was less than that from the narrower sized fractions. The separation density decreased with increasing column height. The lowest E value was seen for a column height of 1500 ram, for which conditions the separation density was 1.45 g/cm3. The E value was 0.084 for the 0.25-0.5 mm fraction but the corresponding separation density was 1.48 g/cm3, and the E value 0.089, for the broader 0.25-1.0 mm fraction.

目的针对足月妊娠引产使用Foley导管低位水囊与小剂量米索前列醇的临床效果展开分析与探讨。方法研究对象的纳入时间在2021年1月—2022年12月,均为本院收治的延迟妊娠、妊娠合并症的足月孕妇,共计172例,根据引产方法不同,划分为Foley导管组(76例,Foley导管低位水囊+小剂量缩宫素)、米索前列醇组(36例,小剂量米索前列醇与小剂量缩宫素联合应用),缩宫素组(60例,单纯小剂量缩宫素静脉滴注),针对三组宫颈成熟有效性、不良反应、宫颈Bishop评分、产程时间及引产成功率实施对照分析。结果相比缩宫素组,其他两组宫颈成熟总有效率均明显更高(P0.05);Foley导管组、米索前列醇组干预12h后宫颈Bishop评分均高于缩宫素组(P0.05)。Foley导管组、米索前列醇组引产成功率均高于缩宫素组(P<0.05),且Foley导管组数据相比米索前列醇组更高(P<0.05)。结论 Foley导管低位水囊与小剂量米索前列醇的使用,都能够使足月妊娠引产效果显著提升,其安全性良好,有助于提高宫颈成熟效果,特别是Foley导管低位水囊,费用低,副作用小,值得基层医院普及。

提高革命老区农户生计韧性有利于巩固拓展脱贫攻坚成果,促进革命老区振兴发展。本文基于2022年太行革命老区实地调查数据,构建“风险冲击-生计韧性-生计韧性提升策略”理论分析框架,在健康风险冲击、市场风险冲击和自然风险冲击视角下,从缓冲能力、自组织能力和学习能力3个维度测度农户生计韧性,采用结构方程模型分析风险冲击对农户生计韧性的影响路径,并探讨提升农户生计韧性的策略。结果发现:第一,健康风险冲击对农户生计韧性影响程度最大,负向影响作用大小依次为缓冲能力、学习能力和自组织能力;第二,市场风险冲击通过影响缓冲能力、自组织能力和学习能力对农户生计韧性产生负向显著影响,三者影响作用水平相当;第三,自然风险冲击对农户生计韧性产生正向显著影响,农户在长期农业生产实践中易于形成对自然风险冲击的预期,且能够选择种植更适合当地气候的作物品种和更适宜的耕作方式,增强适应和应对能力,从而提高自身生计韧性。此外,通过不同群体农户生计韧性的异质性分析发现,在巩固拓展脱贫攻坚成果、全面推进乡村振兴过程中仍应进一步关注脱贫户和脱贫村农户的生计韧性。
