俗字纷出是古代碑刻文献的显著特征,也是碑刻整理史上的大问题。即使改进碑拓处理技术,拓展研究领域,也未能改变现况。石本转作碑刻文本时必定要面对疑难字等文字问题,文字释读始终是碑刻文献整理中的核心环节,应当结合字形俗变规律,合理把握形变特征,科学分析形体来源,仔细推敲文意表达,适时参考字书载录,从而作出准确识断。尤其是一些希见、新出字形,通常处于字群系统边缘,更要着力审辨。文章以文博期刊新近刊布的几种隋唐碑志拓本为依据,选择考释其中的疑难俗字,釐析思路,探求字源,究明理据,理顺文意,还原文献,延伸拓展,旁及他字,订正误释,一则为新碑志材料的研究和利用提供有效支撑,也为碑刻俗字释读考辨、汉语汉字史研究提供参考。 相似文献

目的:建立同时测定金匮肾气片中黄芩苷和丹皮酚含量的高效液相色谱法。方法:采用C18色谱柱(4.6 mm×250 mm,5μm),以甲醇-0.1%磷酸水溶液(52:48),检测波长278 nm,柱温30℃,流速1.0 mL/min。结果:黄芩苷在0.485~19.406μg/mL,丹皮酚在1.079~43.157μg/mL线性关系良好。平均回收率(n=9)分别为99.6%,100.5%,含量测定结果表明,不同批次金匮肾气片之间黄芩苷和丹皮酚含量水平差异不大。结论:经方法学验证,该法可用于金匮肾气片中黄芩苷和丹皮酚含量的快速测定。 相似文献

如何服用钙片才能达到更好的效果——钙片在模拟胃液中溶解性实验 总被引：1，自引：0，他引：1
选取3种具有代表性的主要成分分别为无机酸钙、有机酸钙、有机钙钙片为研究对象,根据人体的特点以及食物在胃中消化过程,选择合适的溶液作为模拟胃液,构造类似人体消化食物的各种环境,重点研究钙片溶解转化为可吸收的Ca2情况,采用双波长分光光度法测定溶液中Ca2+的含量.实验结果表明:3种不同钙源的钙片在胃液中溶解情况无明显差别;钙片应在两餐之间服用;如果片剂中注明的含量较高如600 mg/片,应分开多次服用;在服用钙片期间应尽量避免和碳酸类、酒精类饮品等同食. 相似文献

ABSTRACTTouch screen tablets are being increasingly used in schools for learning and assessment. However, the validity and reliability of assessments delivered via tablets are largely unknown. The present study tested the psychometric properties of a tablet-based app designed to measure early literacy skills. Tablet-based tests were also compared with traditional paper-based tests. Children aged 2–6 years (N?=?99) completed receptive tests delivered via a tablet for letter, word, and numeral skills. The same skills were tested with a traditional paper-based test that used an expressive response format. Children (n?=?35) were post-tested 8 weeks later to examine the stability of test scores over time. The tablet test scores showed high internal consistency (all α’s?>?.94), acceptable test-retest reliability (ICC range?=?.39–.89), and were correlated with child age, family SES, and home literacy teaching to indicate good predictive validity. The agreement between scores for the tablet and traditional tests was high (ICC range?=?.81–.94). The tablet tests provides valid and reliable measures of children’s early literacy skills. The strong psychometric properties and ease of use suggests that tablet-based tests of literacy skills have the potential to improve assessment practices for research purposes and classroom use. 相似文献

Emanating from the ground-breaking Library Impact Data Project, the aim of the Roving Librarian project first initiated in 2011 was to offer personalized help outside of the traditional library to library non-users in social or academic settings using Android and the iPad tablets. It was thought that the portability and flexibility of these devices would allow staff to reach students and help them at their point of need. To test out this premise, an action study was carried out to examine the use of tablets and their suitability in facilitating the roving librarian project as well as evaluate roving as a vehicle for teaching information literacy on the move. Data was collected through peer observation, individual reflections, and a questionnaire conducted with subject librarians to find out more regarding their usage of the tablet and to ascertain whether they have found it conducive in roving. The project demonstrated that the affordances of both devices enabled librarians to provide personalized mobile help to students whilst building stronger relationships and arguably having the type of conversations about library resources and facilities that would not have happened if staff had stayed within the physical library building. 相似文献
