研究了用电子自旋顺磁共振(ESR)法对香烟烟气中的自由基进行分析的样品处理方法及ESR检测方法.对四种英国产香烟样品中的粒相及气相自由基进行了分析检测并对检测结果进行了讨论.结论:大多数英国产的检测样品香烟中,含有1.5~3倍于国产对照香烟样品的气相自由基;而国产对照样品香烟的粒相自由基的含量水平则处于较高水平.实验结果还显示:同品牌的Sobranie香烟中,不同型号样品中粒相自由基含量与焦油含量具有负相关性,但不同品牌则不同;对于检测样品而言,气相自由基的含量与焦油含量有正相关性. 相似文献

我国物权法第一百零七条对遗失物善意取得制度的规定,文义上没有区分受让人主观善意;逻辑上存在概念不周延和矛盾的问题;制度功能上并没有真正平衡原权利人与善意受让人之间的利益冲突,对于交易安全保护的目的也没有彻底实现。结合国外立法的经验,我国立法应承认遗失物善意取得制度。 相似文献

宋代环卫官从唐代十六卫官承袭而来,在名称和编制上无太大变化,但由于宋朝历代都遵从"崇文抑武"的"祖宗家法",环卫官的职能范围越来越小,以致两宋以来环卫官多不除人。从现存的宋代史料中可以发现,宋代环卫官经历了三个阶段的演变,在《宋史》的"合班之制"和宋代的官品令中尤其可以发现这些变化。这也反映了宋代在中国古代历史上处于从中央集权专制到皇权专制主义的转型期。研究宋代集权的就为角度之一。 相似文献

The paper examines the impact of the plethora of innovations associated with the 1988 Education Reform Act (ERA) on the management of whole-school change in the primary school. Based upon qualitative data from a national sample of 50 schools in England and Wales, it documents the growing tensions between collegial and top-down managerial approaches. These are evidenced in the changing nature of working collaboratively in primary schools, in the creation of new management structures, in the me of school development plans and in the growth of quality assurance mechanisms, particularly in relation to preparation for Office for Standards in Education (OFSTED) inspections. There are conflicting interpretations of terms such as ‘collegiality’, ‘collaboration’, ‘teamwork’ and ‘whole-school approaches’ and there have been subtle shifts in their meaning and in their realisation in practice in the pre-and post-ERA context. 相似文献

The pedagogical practices of mathematics education for young children in English and Korean pre-schools were compared through analyses of interviews with practitioners, observations of classroom activities and an examination of documents related to the planning and implementation of mathematics education. Practitioners in both countries used integrated activities to teach mathematics, although they used such activities more frequently in nurseries than in reception classes in England and more frequently in state settings than in independent settings in Korea. Furthermore, mathematics education was more structured, more likely to be led by an adult and less holistic in reception classes than in nurseries in England, whereas it was more structured and didactic in independent than in state settings in Korea. However, mathematics education in England was more systematic, used a more individualised approach and incorporated a variety of hands-on materials and rigorous outdoor activities, whereas it was more group-oriented and utilised limited materials and fewer outdoor activities in Korea. 相似文献

盗赃的善意占有问题是一个现实性很强的问题。它是否适用善意取得制度,它与善意取得制度究竟是怎样的关系?这些问题在我国无论是理论界还是司法实践中。都存在着不同的观点。从善意取得制度的功能入手,通过对盗赃善意占有性质分析,通过与国外对同一问题规定的比较,可以揭示我国关于盗赃善意占有制度的不足。 相似文献

Teaching portfolios have become commonplace in the US in teacher education programs, in the process of granting an initial teaching license, in teacher recertification, and in National Board certification. This paper focuses on the use of teaching portfolios in preservice teacher education programs and analyzes the various ways in which portfolios have been conceptualized and implemented. A conceptual framework is proposed to enable researchers to describe the conditions of portfolio use. A presentation of the conditions of portfolio use will enable a greater understanding of the ways in which teaching portfolios impact teacher development and the quality of teacher assessments under different conditions of use. The paper concludes with a discussion of the key issues that have emerged in the use of teaching portfolios in preservice teacher education in the US. 相似文献

《毛诗》于平帝元始五年立于学官,终王莽之世。《鲁诗》立于学官在武帝为博士置弟子员之后。《齐诗》立于学官不迟于昭帝元凤元年。《韩诗》可能是在昭帝始元五年立于学官。学者或以为三家《诗》立于文景之世,或以为立于武帝置五经博士时,或以为三家分派在石渠阁会议之后,以及以为《毛诗》是元始四年立于学官的,都是错误的。文景之时尚无专经博士;武帝置五经博士明确了其顾问团为儒家性质,当时经派意识尚不明晰;石渠阁会议之前三家已经分派,史书叙宣帝增置前博士不数《诗》博士,是因《诗》博士在宣帝增立时无所增立。 相似文献

Most countries in Africa have introduced the use of local languages as the language of learning and teaching for the first
few years of schooling. Meaning that for the first few years of learning, learners learn mathematics in their local languages.
In response to this, most research has focused on the challenges of using local languages in multilingual mathematics classrooms
in schools. Not much research focuses on how the teacher educators prepare the prospective teachers to teach mathematics in
multilingual classrooms. To further knowledge in the area of multilingualism in mathematics education, I, in this paper, present
an analysis of the literature on multilingual teacher education in Africa. Specifically, I look at what it is that governments
in interested countries are doing in teacher education programs in response to the introduction of local languages in schools.
From the literature examined, I found that although there is awareness in a number of countries of the need for multilingual
teacher education, not much has been done in order to train mathematics teachers on how to use local languages in the classroom.
I therefore recommend that, for those countries that have implemented or planning to introduce the use of local languages
in schools, some reforms should also take place in teacher education programs in terms of training the prospective teachers
how to teach in local languages. 相似文献
