对比研究锌电积电解液中氟、氯对Pb-Ag阳极恒流极化(500 A/cm^2.72.h后氧化膜层表面形貌、内部结构、物相组成和基底腐蚀的影响。结果表明:氟、氯抑制PbO_2.生长,提高膜层中PbOn、PbO·PbSO_4的含量。在含氟溶液中,氧化膜层表面呈鳞片状,内部孔洞、空隙增多,致密度降低;基底出现腐蚀孔洞,随着氟浓度增大,腐蚀孔洞增多、孔径增大、腐蚀深度变大。在含氯溶液中,氧化膜层表面呈胶结状,致密度与无氯电解液中的相当,但紧密层厚度明显减小;基底出现腐蚀坑,腐蚀深度小于含氟溶液中的。此外,分析了氟、氯对Pb-Ag阳极腐蚀行为的影响机制。氟主要通过降低氧化膜层致密度加剧Pb-Ag阳极的腐蚀,而氯主要通过减小氧化膜层厚度加剧阳极的腐蚀。

Chemerin作为一种多功能脂肪因子,通过内分泌和旁分泌起作用,它可以与已知的三个受体(ChemR2.、GPR1和CCRL2.结合参与能量代谢、糖脂代谢和炎症等多种病理生理过程,尤其在代谢性疾病中发挥重要作用。多囊卵巢综合征(polycystic ovary syndrome,PCOS)是最常见的内分泌疾病之一,严重困扰育龄女性的正常生活。PCOS患者血清chemerin含量显著升高,且其卵巢中chemerin高表达。越来越多的研究表明chemerin通过影响肥胖症、胰岛素抵抗、高雄激素血症、氧化应激和炎症反应等参与PCOS的发生和发展过程。本文主要综述了chemerin蛋白的产生、亚型、功能和受体,从代谢、生殖、炎症等角度总结并探讨chemerin蛋白在PCOS中的研究现状,为PCOS的临床诊断和治疗提供理论基础和参考依据。

在超冷费米气体中,通过调节自旋轨道耦合的强度,使其与费米能量相当,可以产生许多新奇的量子效应。在过去几十年里,学者对于一维自旋轨道耦合诱导的费米气体进行了大量的理论和实验研究。与高维自旋轨道耦合相比,一维自旋轨道耦合虽然显得比较简单,但它是实验上探索基本量子物理现象的最可靠和最易行的工具。本文系统地整理了理论工作中一维自旋轨道耦合下费米气体的有趣物理现象。包括动力学振荡和孤子效应、拓扑超流、Majorana边缘态、铁磁相变和量子相位方面的理论研究。在实验中,如何实现自旋轨道耦合并且观测奇异现象,是研究的热点和难点问题。我们梳理了几种常见的实验方案和检测方法,最后对一维自旋轨道耦合诱导下费米气体方面的研究进行展望。一维自旋轨道耦合可以为初学者提供借鉴,有助于研究自旋轨道耦合调控的多体系统。本文期望为冷原子物理初学者深入理解自旋轨道耦合下多体系统的物理机制提供参考。
