In this paper,we discuss properties of SDSS J1042-0018 which is a broad line active galactic nucleus(AGN)but misclassified as an H II galaxy in the BPT diagram(SDSS J1042-0018 is called a misclassified broad line AGN).The emission lines around Hαand around Hβare well described by different model functions,considering broad Balmer lines to be described by Gaussian or Lorentz *** model functions lead to different determined narrow emission line fiuxes,but the different narrow emission line fiux ratios lead SDSS J1042-0018 as an H II galaxy in the BPT *** order to explain the unique properties of the misclassified broad line AGN SDSS J1042-0018,two methods are proposed,the star-forming contributions and the compressed narrow emission line regions with high electron densities near to critical densities of forbidden emission ***,the strong star-forming contributions can be preferred in SDSS *** misclassified broad line AGN SDSS J1042-0018,well explained by star-forming contributions,could provide further clues on the applications of BPT diagrams to the normal broad line AGNs.

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

数字经济时代,密码技术作为保障信息安全的核心技术,其重要性日益凸显。而密码技术的广泛运用也可能影响国家安全和公共利益。因此,密码技术的运用和规制一直寻求私权保护与执法需求、市场驱动与政府干预、贸易自由与国家规制之间的平衡。近年来,CPTPP和DEPA等高标准国际经贸协定相继纳入使用密码技术的ICT产品规则,一方面要求减少对使用密码技术的ICT产品不合理的贸易限制,强化数字知识产权保护;另一方面也尊重国家对密码技术的规制权,包括金融机构和市场例外、执法机关例外等限制性规则。中国在积极推进加入CPTPP和DEPA的过程中,应积极对接密码技术产品规则,大力发展商用密码技术,加强与CPTPP和DEPA成员国在密码技术和网络安全领域的合作与信息共享,并进一步完善密码技术管理的政策法规。

基于共生理论和社会网络分析,从成渝地区旅游同质度、关联度、外向功能强度3个维度测评并分析成渝地区双城经济圈旅游业共生水平现状.通过分析得出:成渝地区双城经济圈旅游业的同质度和重合度均较高,成都市、重庆主城区、渝西毗邻片区3个片区处于成渝双城经济圈旅游共生的中心主导地位,成都是连接四川省其他地区和重庆片区的桥梁.广安市、达州市、资阳市与重庆地区虽联系较多,但是外向功能强度不高,还未发挥出旅游的带动和桥梁作用.成渝地区双城经济圈中旅游关系存在4个子群,重庆地区与川南地区子群具有较强的影响力,川东北与重庆毗邻地区是最具潜力子群.据此,从建立分工基础上的对称互惠一体化共生模式、营造良好的旅游市场一体化共生环境、打破行政区划创造多元旅游共生界面3个方面提出成渝地区双城经济圈旅游共生发展的对策建议.
