A novel integrated nanobiocatalyst system based on an enzyme@silica nanoflower@metal-organic framework （enzyme@SNF@ZIF-8） structure with improved stability is fabricated for the first time. The versatility of this system is validated using penicillin G acylase （PGA） and catalase （CAT） as model enzymes. The microporous ZIF-8 layer can be controlled by varying the number of ZIF-8 coating cycles, which produces PGA@SNF@ZIF-8 nanobiocatalysts with different ZIF-8 layer thicknesses. After the second ZIF-8 coating cycle, a PGA@SNF@ZIF-8（2） structure with a homogeneous and well-intergrown ZIF-8 layer is formed, which possesses excellent mechanical and chemical stability. Moreover, PGA@SNF@ZIF-8（2） shows improved thermal/storage stability and reusability compared with free PGA and PGA immobilized on silica nanoflowers （PGA@SNF）. The obtained CAT-based nanobiocatalysts （CAT@SNF@ZIF-8（2）） also show excellent catalytic performance.

研究了在较强光低饱和限制下相干光场与N型四能级原子相互作用系统中原子的吸收性质。借助于数值计算,讨论了较强光失谐、探针光强、激发能级向低能级衰减的分配系数对原子吸收的影响。结果表明,抽运场失谐使原子吸收发生横向变化,信号场失谐使原子吸收发生纵向变化;探针光强影响非线性吸收,并通过它影响原子吸收,当探针光强远小于抽运和信号光强时,原子吸收与线性吸收一致,均表现为电磁感应透明特征,当信号光强增大,非线性吸收产生了增益,原子吸收也由透明变为增益;激发能级同时向两个低能级衰减,当对应探针光的原子衰减通道的衰减分配系数趋近零时,原子吸收随该系数变化非常强烈,当该分配系数等于零时,其增益在探针场共振处趋于无穷大。

《中小学教育惩戒规则(试行)》明确"停学"是教育惩戒措施的一种,但如何实施"停学",特别是如何平衡其与义务教育阶段学生的受教育权的关系则亟待说明。为此,文章通过对日本具有与"停学"相似效果的"出席停止"制度的考察,分析梳理其制度形成、法律性质和具体内容,提出落实我国义务教育"停学"措施的具体建议:谨慎使用"停学"措施,细化"停学"适用条件,在"尽可能短"的原则下综合判断"停学"时长,完善"停学"实施程序,构建"停学"期间的多主体学生指导机制。

在理论上研究了电磁感应透明(EIT)介质的高阶非线性特性。引入一种区别于迭代法的新方法,该方法基于暗共振的分布情况,得到跃迁密度矩阵元的全解,在此基础上得到原子体系对探针光的各阶响应。研究结果表明,线性(一阶)极化率表现破坏性相干,非线性(三阶)极化率表现建设性相干;在各向同性介质中偶数阶次的非线性响应消失。进一步研究发现,五阶极化率和线性极化率一样呈现破坏性相干。研究结果为探索光波在EIT介质传输过程中高阶非线性对光波演化的影响提供了理论依据。该方法为研究高阶非线性效应提供了一种新的理论途径。

选择上海社保基金案为研究对象,根据2004~2008年年末注册地为上海的上市公司的年报、临时公告和纸质新闻媒体报道资料,手工搜集了关键高管（董事长与总经理）的政治联系数据和公司涉案与否的数据,实证研究了涉案行为与政治联系之间的关系,以及涉案行为在上海社保基金案之前、期间和之后对公司审计意见的影响。研究结果表明,政治联系的上市公司显著地更可能涉案,且在上海社保基金案曝光的2006年,涉案公司被出具非标审计意见的概率显著更高;但若以2006年为基准,在上海社保基金案之前的2004~2005年、之后的2007~2008年,涉案公司被出具非标审计意见的概率显著更低。
