The catalytic behavior of a catalyst for chlorine-containing volatile organic compounds（CVOCs） oxidation largely depends on the synergistic interaction between the oxidizing and acidic *** the present work,two catalysts with different distributions of CeO2on the inner and outer surfaces of 4.0Ce-USY-ex and 4.0Ce-USY-dp（USY zeolite） were prepared respectively by ion exchange and deposition methods,with a purpose of finding out how the location of the oxidation sites（CeO2） influence its synergistic effect with the acidic sites of *** results show that 4.0Ce-USY-ex is much more active for catalytic degradation of 1,2-dichloroethane（DCE）,while 4.0Ce-USY-dp catalyst exhibit higher catalytic degradation activity for other structured CVOCs(dichloromethane（DCM）,trichloroethylene（TCE）,chlorobenzene（CB）).CeO2in 4.0Ce-USY-ex catalyst mainly disperses in the pore channels of USY zeolite,and there are many strong acid centers on the surface,which is conducive to the dechlorination conversion of ***,CeO2in 4.0Ce-USY-dp catalyst is mainly distributed on the outer surface of USY and has strong oxidation ability,which contributes to the deep oxidation of ***,the presence of a large number of strong acid centers on the catalyst surface of 4.0Ce-USY-ex catalysts leads to severe accumulation of surface carbon species and significantly decreases its stability towards ***,a large number of active oxygen species on the surface of 4.0Ce-USY-dp and CeO2catalysts are beneficial to the deep oxidation of DCE,reducing the formation of surface carbon and thus improving the stability of the ***,the influence of the location of the oxidation sites on its synergistic effect with the acidic sites was established in the present work,which could provide some new ideas for the rational design of CVOCs degradation catalyst with appropriate distribution of active sites.

作为新兴的人力资源管理实践,发展型人力资源管理实践能够对员工的工作动机、行为产生积极影响。然而,在中国本土文化情境下,鲜有文献涉及发展型人力资源管理实践如何影响员工主动变革行为。基于资源保存理论和“能力—动机—机会(AMO)”框架,探讨发展型人力资源管理实践对员工主动变革行为的影响机制和边界条件。通过对三阶段349份有效样本的分析发现,发展型人力资源管理实践对员工主动变革行为具有显著正向影响;员工工作重塑在发展型人力资源管理实践与员工主动变革行为间发挥部分中介作用;中庸思维会进一步强化发展型人力资源管理实践与主动变革行为间关系,且该调节效应会被工作重塑中介。

针对光伏逆变器的绝缘栅双极型晶体管(insulated gate bipolar transistor,IGBT)接线故障不易发现且易被忽略,现有方法诊断速度慢、识别率低的问题,提出了一种基于电压均值的特征提取策略,并利用改进狮群算法(improved loin swarm optimization,ILSO)优化核极限学习机(kernel extreme learning machine,KELM),实现对IGBT的故障诊断.首先,分析逆变器各状态下三相电压Concordia变换后的效果,获得表征故障特征的二维向量,通过二维散点图验证接线故障的可分性;其次,通过Sine混沌映射改进的狮群算法(loin swarm optimization,LSO)对KELM进行参数寻优,建立诊断模型;最后,以Z源逆变器为例进行验证.结果表明:对于逆变器的IGBT接线故障,所提方法能提取包含丰富故障信息的二维故障特征,极大地简化了特征提取的过程,且诊断方法适用于单个和2个器件的故障类型,与其他方法相比速度更快,故障识别率更高.

In this paper, firstly, a new notion of generalized cone convex set-valued map is introduced in real normed spaces. Secondly, a property of the generalized cone convex set-valued map involving the contingent epiderivative is obtained. Finally, as the applications of this property, we use the contingent epiderivative to establish optimality conditions of the set-valued optimization problem with generalized cone convex set-valued maps in the sense of Henig proper efficiency. The results obtained in this paper generalize and improve some known results in the literature.

1例67岁女性Ⅳ期右肾癌术后复发伴颅内多发转移癌患者使用索拉非尼联合信迪利单抗治疗,2周内患者出现发热、颜面部、背部、臀部及四肢红色花斑样皮疹;2 d后发热完全缓解,但双侧肘关节处、臀部及双侧大腿外侧皮肤出现皮下渗液,之后逐渐出现表皮松解脱落伴皮肤破溃;4 d后患者表皮松解面积> 30%体表面积,诊断为中毒性表皮坏死松解症(TEN)。采用ALDEN评分进行不良反应关联性评价,判断TEN“很可能”由索拉非尼和信迪利单抗共同诱导。停药治疗后患者TEN痊愈。本文探讨TEN与联合使用索拉非尼和信迪利单抗的相关性及处置措施,可为早期识别和正确治疗该疾病提供参考。

China has undergone tremendous economic growth,but there still remains much room for improvement inemergency medical service （EMS） system.[1] The EMSin China comprises of three parts： the pre-hospitalemergency service, the emergency department, andthe intensive care unit. Not much is known about theexact numbers of out-of-hospital cardiac arrest （OHCA）across the whole of China, though there are reports fromspecifi c provinces.
