采用反相悬浮聚合法合成了聚丙烯酰胺-甲基丙烯酸（P（AM-co-MAA））微凝胶,并以其作为模板,通过热解法制备了一系列微米级、表面具有特异结构的P（AM-co-MAA）/SnO2有机-无机复合微球材料.详细考察了反应时间、SnCl4的浓度和热解温度等因素对复合微球的形貌结构的影响.通过SEM,XRD,FT-IR,TG等手段来表征复合微球的结构、形貌、含量.微球上沉积的SnO2层随着SnCl4的浓度增大而加厚.采用模板法制备复合材料具有操作过程简单、反应条件温和等特点,因此,可将此方法可进一步拓展到其他有机-无机复合材料的制备中. 相似文献

<正>Heterogeneous catalysis is a key technology for chemical and materials synthesis,fuel production,power generation and conversion,and environmental remediation.To cope with resources(energy)shortage and environmental pollution,chemical processes should be not only effi cient but also clean,and catalysts must be active and selective.The innovation of such catalysts requires a fundamental understanding of the structure-activity relation of catalysts that can guide the design of catalyst structures. 相似文献

Current undergraduate medical school curricular trends focus on both vertical integration of clinical knowledge into the traditionally basic science‐dedicated curricula and increasing basic science education in the clinical years. This latter type of integration is more difficult and less reported on than the former. Here, we present an outline of a course wherein the primary learning and teaching objective is to integrate basic science anatomy knowledge with clinical education. The course was developed through collaboration by a multi‐specialist course development team (composed of both basic scientists and physicians) and was founded in current adult learning theories. The course was designed to be widely applicable to multiple future specialties, using current published reports regarding the topics and clinical care areas relying heavily on anatomical knowledge regardless of specialist focus. To this end, the course focuses on the role of anatomy in the diagnosis and treatment of frequently encountered musculoskeletal conditions. Our iterative implementation and action research approach to this course development has yielded a curricular template for anatomy integration into clinical years. Key components for successful implementation of these types of courses, including content topic sequence, the faculty development team, learning approaches, and hidden curricula, were developed. We also report preliminary feedback from course stakeholders and lessons learned through the process. The purpose of this report is to enhance the current literature regarding basic science integration in the clinical years of medical school.

近年来基于字的词位标注的方法极大地提高了汉语分词的性能,该方法将汉语分词转化为字的词位标注问题,借助于优秀的序列标注模型,基于字的词位标注汉语分词方法逐渐成为分词的主要技术路线。本文简要介绍了词位标注汉语分词的基本思想,探析了基于条件随机场实现词位标注汉语分词的机理,并对采用四词位标注集,使用CRF＋＋0.53工具包实现字串序列词位标注进行了详解。最后在Bakeoff2006的评测语料上进行了封闭测试。 相似文献

以正硅酸四乙酯（TEOS）为硅源,十二胺（DDA）为模板剂制备HMS介孔分子筛,考察了模板剂脱除方法对HMS介孔分子筛结构的影响.结果表明：采用高温焙烧法脱除模板剂简单易行,但对分子筛结构有部分破坏作用;而采用溶剂萃取法脱除模板剂,介孔结构的有序性能得到很好的保持,但是周期较长.最后针对两种方法的优缺点,提出了各自的改进方法. 相似文献
