将低共熔溶剂(DES)接枝到金属有机框架ZIF/磁性还原氧化石墨烯(MG)制备了一种复合吸附剂(DES@ZIF@MG),用于吸附水中甲基苯丙胺。采用SEM、FT-IR、BET、VSM、TGA等表征研究复合材料的微观形貌及理化性质。通过吸附动力学、吸附等温线以及吸附影响实验(pH、离子浓度和腐殖酸)探究吸附剂对甲基苯丙胺的吸附性能及机理。结果表明:吸附剂DES@ZIF@MG对甲基苯丙胺的吸附符合准二级动力学模型和Langmuir等温模型,说明吸附过程是以化学吸附为主导的能量均匀吸附。结合XPS表征进一步分析,DES@ZIF@MG对甲基苯丙胺的吸附过程中主要存在氢键作用、π-π作用、静电作用以及螯合作用。

从量化角度分析回墨印章印文阶段性规格特征,探讨该特征作为回墨印章印文形成时间鉴定依据的可行性。利用Auto CAD对一年内回墨印文自然样本的长度和角度进行测量,应用SPSS数据处理软件对测量结果进行处理分析,得出在不同时间范围内的印文规格特征变化规律及变化阈值。通过多人多次重复试验,回墨印文规格特征变化值随盖印时间的增长总体呈增大趋势,但增加值与盖印时间间隔值无直接对应比例关系,规格特征测量结果受环境及人为因素影响较大。可通过回墨印文规格特征变化趋势来辅助检验回墨印章印文盖印时间。

利用2014—2018年中国家庭追踪调查数据,采用面板固定效应模型和工具变量方法,考察孩子数量对已婚女性就业选择的影响。研究表明,孩子数量会显著增加已婚女性的自雇就业率,还会降低其正规就业率,但随着孩子年龄的增加,这种影响会减弱。孩子数量对已婚女性就业选择的影响还存在受教育水平、城乡、丈夫特征等异质性差异。进一步研究发现,当生育孩子数量增加,使用电脑上网会提高女性的自雇就业率。该研究丰富了生育对女性就业影响的文献。
