镁合金由于密度低、比强度高、电磁屏蔽性能良好而广泛应用在航空航天、汽车、数码等重要领域,但其较差的腐蚀性能使进一步应用受到限制。稀土元素原子的晶体结构与Mg原子相同,在α-Mg中具有较大的固溶度,形成的金属间化合物第二相可细化合金晶粒,同时加入稀土元素可改变腐蚀层结构,进而可以有效地改善镁合金的耐腐蚀性能。通过X射线荧光光谱仪、光学显微镜、扫描电子显微镜、电化学站测试、原子力显微镜等测试设备,表征了Mg-3.4Y-3.6Sm-2.6Zn-0.8Zr合金在3.5%NaCl溶液(质量分数)中的腐蚀速率和腐蚀形貌,研究了析出相对稀土镁合金腐蚀行为的影响。结果表明,稀土元素Y和Sm在镁合金中形成了(Mg,Zn)_(3)(Y,Sm)和Mg_(12)(Y,Sm)Zn 2种析出相,在合金腐蚀过程中(Mg,Zn)_(3)(Y,Sm)相最先被腐蚀,随后是α-Mg基体和Mg_(12)(Y,Sm)Zn相。析出相在合金腐蚀过程中形成了均匀的腐蚀产物膜层,增大了合金的电化学阻抗值,腐蚀产物膜层对合金起到了保护作用,有效地降低了合金的腐蚀速率。

目的总结线状IgA大疱性皮病(LABD)患者的临床、免疫血清学和治疗特点。方法回顾性收集2016—2023年就诊于中国医学科学院皮肤病医院诊断为LABD的患者资料,分析其临床、免疫血清学和治疗特征。结果共纳入LABD患者26例,女14例、男12例,年龄[M(Q1,Q3)]为32(11,48)岁。26例患者中12例(46.2%)表现为典型的花环样红斑、水疱,14例(53.8%)表现不典型,即非花环样排列的红斑、水疱。直接免疫荧光检查阳性率为73.7%(14/19)。盐裂皮肤-间接免疫荧光(ss-IIF)检查阳性率为53.8%(14/26),均表现为IgA伴或不伴IgG沉积在表皮侧。免疫印迹实验检测到IgA抗体阳性率为88.5%(23/26),18例(69.2%)患者血清IgA可识别相对分子质量120000的线状IgA抗原1(LAD-1),其中4例IgA同时识别BP180;1例(3.8%)IgA识别表皮提取物中相对分子质量约170000的蛋白;1例(3.8%)IgA识别表皮提取物中BP230和相对分子质量为140000的蛋白;1例(3.8%)IgA可识别相对分子质量为290000的Ⅶ型胶原。21例患者对氨苯砜治疗反应良好,1例疗效欠佳,1例不耐受,此2例使用托法替布亦不能达到完全缓解;3例使用米诺环素、秋水仙碱、柳氮磺吡啶等治疗有效。结论本组LABD患者中青年多见,LAD-1是最常见的靶抗原,免疫印迹实验检测IgA抗体的阳性率较免疫荧光检测法高,是鉴别诊断的重要手段。虽然LABD对氨苯砜反应良好,但仍需探索其他安全有效的药物。

基于零部件的基本库存水平补货策略,在多周期订单产品需求不确定情况下构建两阶段随机优化模型:第一阶段在需求未知情况下,规划不同零部件基本库存水平决策变量,实现系统收益最大化;第二阶段针对订单交货期约束创新性设计订单指派决策变量,考虑在不确定需求收益和订单延期惩罚情况下,最大化订单期望收益.通过采样获取不同需求场景,并将不确定需求转成期望需求,针对该期望需求下的单阶段确定性模型求解,并与随机模型结果进行对比.数值实验表明,随机模型的优化结果远差于确定性模型,即未知信息具有一定的价值;同时通过对模型中参数的灵敏度分析,得到了实际中提升系统收益的策略.

生成式人工智能(AIGC)融入社会生活、参与知识生产,同时在塑造新的数字不平等现象,学界对数字鸿沟固化与深化的担忧也与日俱增。本文聚焦数字中国建设的战略背景,延续人工智能发展及其社会影响的理论脉络,重点回答AIGC如何形塑“智能沟”这一问题。技术机理层面,“智能沟”包含数据、算法和算力三个维度;社会影响层面,体现为社会分层理论向数字领域的延伸,表现为人人分化、人机分化两个维度,本质上是国家、区域或个体运用数字资源参与发展、共享发展与自主发展的能力差异;弥合路径层面,需构筑自立自强的技术创新体系、建立公平规范的平台治理生态、拓展开放共赢的国际合作格局。本文提出的“智能沟”概念不仅是第三代数字鸿沟理论在人工智能领域的深化,而且对于理解数字中国发展与经济社会转型具有重要现实意义。
