付怡欣  杨宇  陈月宽  张绍基 《科教文汇》2020,(7):91-92,101

2016年7月30日,输血医学正式成为临床医学二级学科,输血医学也迎来了新的机遇和发展点。然而目前,输血医学人才培养模式尚未完全建立,且依然参照既往医学检验专业人才的培养模式来执行,处于定位“模糊”和断档状态。因此,亟需建立一个新的输血医学人才培养模式,培养高素质的输血医学专业人才,抓住新时代背景下的发展契机,拓展输血医学的发展空间,让输血更好地迈入新时代。  相似文献   

Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool

Chang’E-4 landed in the South Pole-Aitken (SPA) basin, providing a unique chance to probe the composition of the lunar interior. Its landing site is located on ejecta strips in Von Kármán crater that possibly originate from the neighboring Finsen crater. A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations. In situ spectra of the regolith have peak band positions at 1 and 2 μm, similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper, which confirms that the regolith''s composition of the landing area is mostly similar to that of Finsen ejecta. The rock spectrum shows similar band peak positions, but stronger absorptions, suggesting relatively fresh exposure. The rock may consist of 38.1 ± 5.4% low-Ca pyroxene, 13.9 ± 5.1% olivine and 48.0 ± 3.1% plagioclase, referred to as olivine-norite. The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle, but representative of the lunar lower crust. Alternatively, the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials. This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool, indicated by the fine to medium-sized texture (<3 mm) of the rock and the SPA-impact melting model [Icarus 2012; 220: 730–43].  相似文献   

信息技术基础课常用教学方法探讨     

付稼荣 《当代教育论坛》2011,(18)

在信息社会,信息技术应当和读、写、算等基本能力一样,成为每个人必须具备的基本素质和基本能力.从培养学生的信息素质出发.选取基础知识和基本技能作为中小学信息技术学科的教学内容,有助于学生跟上信息社会发展的步伐,然而信息技术基础知识的教学,不同于计算机技术操作,如信息的概念、二进制、中央处理器等与学生的现实生活相隔较远,学生不容易理解,相对枯燥,弄不好会给学生乏味无趣的感觉,反而产生相反的教学效果.  相似文献

Internet‐based Science Learning: A review of journal publications     

Silvia Wen‐Yu Lee  Ying‐Tien Wu  Meng‐Jung Tsai  Tzu‐Chien Liu  Fu‐Kwun Hwang 《International Journal of Science Education》2013,35(14):1893-1925

Internet‐based science learning has been advocated by many science educators for more than a decade. This review examines relevant research on this topic. Sixty‐five papers are included in the review. The review consists of the following two major categories: (1) the role of demographics and learners' characteristics in Internet‐based science learning, such as demographic background, prior knowledge, and self‐efficacy; and (2) the learning outcomes derived from Internet‐based science learning, such as attitude, motivation, conceptual understanding, and conceptual change. Some important conclusions are drawn from the review. For example, Internet‐based science learning is equally favorable, or in some cases more so, to learning for female students compared to male students. The learner's control is essential for enhancing students' attitudes and motivation toward learning in Internet‐based science learning environments. Nevertheless, appropriate guidance from teachers, moderators, or the Internet‐based learning environment itself is still quite crucial in Internet‐based science learning. Recommendations for future research related to the effects of Internet‐based science learning on students' metacognitive reflections, epistemological development, and worldviews are suggested.  相似文献

秦贯撰《郑崔合柑墓志铭》真伪考辨     

伏涤修 《中国典籍与文化》2007,(4):19-25

明清时期屡有记载言发现唐代秦贯所撰《郑崔合袝墓志铭》,对此墓志铭的真伪及墓葬主人与《会真记》、《西厢记》原型人物的关系,明清人莫衷一是.本文对明清时期著录、记述《郑崔合袝墓志铭》的相关金石、文史资料进行了梳理与考辨,认为此墓志铭应为真,由于墓葬主人姓郑、姓崔,他们被附会成《西厢记》的原型人物.至于此墓志铭异时异地屡屡出土、墓葬主人名讳不同,则是在《西厢记》的巨大影响下人们对此墓志铭作了复制、改造的结果.  相似文献

中国古代"政府"的图书馆学解读     

傅荣贤 《山东图书馆季刊》2007,(4):1-4

称之为“官府”的我国古代政府是建立在文书档案的收藏及其使用上的，具有非常明显的“图书馆”本性。藏书不仅为政权提供了合法性，而且也为施政和行政提供了依据。相应地，古代作为“史”或“司籍”的图书馆管理员构成了官僚体系的主体并逐步发展为权倾朝野的高级行政官员。  相似文献
