Electric vehicles and portable devices have increased their demand for energy storage,resulting in the development of new high energy density batteries,including solid-state lithium-metal batteries,lithium-oxygen(Li-O_(2))batteries and lithium-sulfur(Li-S)batteries,which utilize high-capacity materials and will significantly break through the dilemma faced by the commercially available lithium-ion batteries[1–3].

The Taurus region is one of the most extensively studied star-forming regions （SFRs）.Surveys indicate that the young stars in this region are comprised of young stellar objects （YSOs） that cluster in groups associated with the molecular cloud （Grouped Young Stellar Objects,GYSOs）,and some older ones that are sparsely distributed throughout the region （Distributed Young Stellar Objects,DYSOs）.To bridge the age gap between the GYSOs （5 Myr） and the DYSOs （10-20 Myr）,we conducted a survey to search for new YSOs in this *** on infrared color excesses and Li I absorption lines,we identified 145 new *** these with the previously identified GYSOs and DYSOs,we constructed a sample of 519 YSOs that encompass the entire ***,we calculated the ages of the samples based on their proximity to the local *** age versus distance to the local bubble (DLB) relationship for the DYSOs shows a clear trend:the farther they are from the local bubble,the younger they are,which is consistent with the supernovae-driven formation scenario of the local *** GYSOs also exhibit a mild age versus ***,they are significantly younger and are mostly confined to distances of 120 to 220 *** their distribution in the age versus DLBspace is well separated from the older DYSOs,they may also be products of the local bubble but formed in more recent and localized events.

文章分别从政策理念、政策目标、政策内容、政策效果四个要素构建生育休假制度分析框架,采用瑞典、丹麦、德国、意大利、英国、美国、日本、韩国和中国有关生育休假制度的二手数据,对不同福利类型国家的生育休假制度进行对比和分析。研究发现,社会福利制度类型深刻影响各国生育休假制度理念,在不同的政策理念影响下,各国在政策目标、政策内容、政策效果方面存在明显差异。当前的生育休假制度的设计理念主要包括“普惠性-双职工”与“补缺性-男性单职工”两种模式;但是随着世界人口与政治形势的变化,两种模式的福利类型国家在操作化层面有趋同的趋势;不同福利类型的国家和地区在生育休假制度目标设计上同时涵盖提升总和生育率与促进女性就业率,但在具体的生育休假期限与生育休假成本分担机制的设计上存在差异;当国家在生育休假成本分担中呈现主体地位时,其总和生育率与女性就业率均呈现出更为积极的发展态势,反之亦反。基于研究结果,建议遵循“普惠性-双职工模式”的政策理念、确定提升生育率和女性就业率双重政策目标、合理设计生育休假期限、彰显国家在生育休假成本分担机制当中的主导作用,以完善我国生育休假制度、促进家庭分工平衡、减轻家庭和企业生育负担、营造生育友好环境。
