人工智能技术不断迭代,ChatGPT和Sora大模型正逐步迈向通用人工智能。为了更好地校准人工智能大模型,各国开始研究价值对齐的技术路径。然而,价值对齐绝非易事,人类社会的价值标准也有很大的差异。如何对齐?标准在哪?目前的价值对齐思路大多基于技术主义的“控制论”,但是,这样的价值对齐可能带来新的伦理风险,并加速“奇点”临近。为此,大模型对齐算法有必要打破传统的“主客体二分法”,摆脱技术主义的思路,以应对道德价值观对齐所带来的独特挑战,追求技术与人文的动态平衡,并在技术人文主义视角下构建“人机共生”关系,实现人与人工智能技术的和谐发展。

单原子催化剂具有催化活性高、选择性强等优点,在非均相催化领域显示出独特的优势。碳基材料作为单原子催化剂的常用载体,具有比表面积大、价格低廉、易于获取等特点,近年来受到广泛关注。随着碳基单原子催化研究的不断深入,相关论文的发表量增长迅速,传统的文献分析方法存在可视化程度低、时间跨度短、覆盖范围小等问题。本文利用CiteSpace文献计量软件对Web of Science核心数据库中2015年1月—2023年3月收录的378篇相关文献进行了可视化分析,讨论了该领域的研究进展及研究热点。结果表明:碳基单原子催化的研究热点主要集中在电催化领域,应用最广泛的载体是氮掺杂碳材料;存在的主要问题有难以催化复杂反应、反应机理不够清晰、配位环境难以精准调控等。本文结果可为碳基单原子催化的研究提供参考。

突发性自然灾害经常对大型工程的建筑与生产设施造成重大损失,而受损设施的维修和重建过程常出现物资供给不足、物资供给效率低以及物资分配公平性等问题。本文以某大型光伏电站为依托,从应急物资节点选址影响因素入手,建立受突发性灾害作用后的应急物资节点选址评价指标系统,采用AHP-CRITIC(analyt⁃ic hierarchy process-criteria importance through intercriteria correlation)组合赋权法实现应急物资存放点选址评价结果的计算。同时,基于研究区内部路网开展大型光伏场地路口至多物资存储节点的最优路径研究,并采用GIS(geographic information system)技术求解出最短运输路径。结果表明:该大型光伏场地应急物资节点选址评价结果等级为“好”与“较好”的区域主要分布在研究区北部,占总面积的33.38%;基于最短运输路径原则通过综合对比线路总长与重复路线占比,由入口3出发至各应急物资节点的路径为最优路线。研究成果可为类似大型工程的安全运营和应急管理提供技术支持和参考。
