矿床学是地质学和资源勘查工程专业的核心必修课程,在地球科学教学体系中占有重要地位,具有极强的综合性、实践性和探索性,单一的传统教学模式无法最大限度地激发学生的学习兴趣.为使学生系统地掌握矿床学的理论知识和研究方法,该文尝试从传统课堂、课后实验和野外实践三方面着手,建立"三位一体"的教学模式,提出在传统课堂讲授和课后实验训练中开展研究性教学,并拓展野外实践教学,初步培养本科生的矿床学综合研究思维.该教学模式的实施旨在培养具有扎实矿床学、矿产勘查学理论知识和实践创新能力的地质学专业本科生.

文章以项目团队指导的长江大学地学专业本科生参与的"大学生创新创业计划"为具体对象,研究与构建适合大学生科研创新能力培养的PBL培养模式,开展教学实践研究与教学效果评价,最后提出有效应用基于PBL大学生科研人才培养模式的对策与建议.

The mudstones of Lower Permian Shoushangou Formation in Xi Ujimqin Qi of Inner Mongolia are well-develoPed source rocks in middle-south Daxinganling Mountains. With study on the characteristics of major,trace and rare earth elements in the mudstones, the PaPer analyzes the Provenance, tectonic setting and weathering of Shoushangou Formation in dePth. The ICV values of rock samPles ranging from 1.15 to 1.57 (averagely 1.33)show that the samPles are basically not affected by secondary diagenesis. According to the A-CN-Κ triangular diagram,the mudstones are subjected to certain Κ-metasomatism. The CIAcorr values of 54.28-70.06 (averagely 65.33)are gained after correction,indicating the Provenance has exPerienced Primary-moderate weathering. Based on the analysis on the multivariable environment of major and trace elements,it is concluded that the argillaceous sediments of Shoushangou Formation are mainly derived from the felsic Provenance,mixed with minus materials from the femic volcanic rock Provenance,under the tectonic background of continental island arc. From the above,it is thought that the sedimentary features of the mudstones in the study area are attributed to the subduction of the Paleo-Asian Oceanic crust in early Permian.

图书馆是高校的文献信息中心,图书馆的文献资源建设工作应充分围绕高校的学科建设及读者的阅读倾向和关注重点来进行.同时,馆藏结构、文献利用率是否合理,将在一定程度上影响高校教学与科研的发展.笔者基于长江大学武汉校区图书馆所用的《interlib3图书馆集群管理系统》的数据,采用定性和定量相结合的方法,从馆藏类目结构、学科分类、复本量统计、馆藏利用等四个方面对该馆的中文图书进行系统地分析研究,以考察馆藏结构合理性及读者的借阅倾向,并以此为基础为高校图书馆文献资源建设工作提出建议.

With the development of higher education,the main point of colleges and universities management has been gradually shifted to the subordinate college,so constructing scientific and effective governance structure of subordinate college and make it to be the subject of running and managing school has been the emphases and difficulties to managers in colleges and universities. Taking the practice of China Jiliang University as an example,the paper discusses how to perfect governance structure of subordinate college from responsibility system assumed by both the Party and the Administration,Party committee management chooses by acclamation, intensifying academic governance, carrying out democratic management,and so on.
