    从大学生宗教信仰角度论大学生的马克思主义宗教观教育

    Get PDF
    近年来,在校大学生的宗教信仰问题越来越受到社会的关注。一方面,不少大学生对宗教表现出浓厚的兴趣;另一方面,大学生的宗教观存在着一定的模糊性。面对"宗教渗透"、"宗教热"现象,高校必须加强对大学生进行马克思主义宗教观的教育

    辅导员在高校抵御宗教渗透工作中的对策思考

    Get PDF
    辅导员作为高校学生思想政治教育管理工作最基层的老师,决定其在抵御宗教渗透中的特殊作用。在日常工作中,辅导员要与所带的每位学生建立情感基础;旗帜鲜明地开展理想信念教育;关注大学生信教的易感人群;及时掌握学生信教情况;主动开展抵御宗教渗透的工作。当前高校辅导员在思想认识、理论水平、信息掌握、工作方法等方面还存在不足,因而学校和政府有关部门要加强对辅导员的宗教知识培训,及时向辅导员通报高校宗教渗透的相关信息,鼓励和支持辅导员对高校宗教渗透问题进行专项研究

    Observation of the induced pressure in a hybrid micro/nano-channel

    This paper studies the flow characteristics in micro/nano-channels subjected to an applied electric field. The nano-channel flow was observed by means of the fluorescence Calcein. A Fluorescence Concentration Gradient Interface (FCGI) was observed across the nano-channel array. The front of the FCGI was shown to have an analogous parabolic shape. The propagation of this interface reflects indirectly the induced pressure at the micro/nano-channel junction, where the enrichment-depletion processes are known to take place. This induced pressure was predicted by numerical simulations, and this paper gives the first experimental evidence

    宗教对当代大学生的影响越来越复杂,基督教在高校的传播和发展已经成为不争的事实。大学生基督教团契是基督教在高校传播的重要基地,是大学生基督教信徒过宗教生活的基本形式。大学生基督教团契带有诱惑性、组织性、隐蔽性等特点。高校、政府及社会应联合起来共同抵御基督教团契对高校大学生群体的渗透。The issue of religious impacts on college students is becoming increasingly complicated.It's a known fact that Christianity is now spreading and gaining popularity in Chinese universities.College students-based religious fellowship is seductive,organizational and secretive,because of which it is considered as the basic organization in spreading Christian and the basic form in college students' religious life.Resistance to the penetration of Christian fellowship among college students should rely on the coordination of colleges,government agencies and related social services and institutes.“教育部高校辅导员培训和研修基地(福建师范大学)”、“福建省高校辅导员专业委员会”(项目编号:JB11610S)研究成

    通过增加饲料中亚硒酸钠的含量,研究了硒对氯化汞在稀有鲫体内积累动力学的影响,探讨了硒对汞富集的影响机制,并给出了两种硒浓度下汞的积累方程。结果表明,饲料中0.2mg/kg的硒对鱼体汞富集无明显影响,2.0mg/kg的硒使鱼体汞富集增加。并且高硒饲料降低了鱼对汞的排除常数,使鱼体总汞的稳态含量增大

    提出了一种加工余弦齿廓齿轮的新方法———滚铣两步加工法。首先采用普通滚齿机滚切出能够完全包裹余弦齿轮的渐开线齿轮,然后采用三轴联动数控铣床进行精加工。分析了加工余弦齿廓的基本原理,建立了滚切加工中齿轮最小模数的数学模型,得出了三轴数控铣齿成形的通用运动控制模型。利用MATlAb软件进行了计算机仿真,验证了模型的正确性和加工方法的可行性。A new method to manufacture the cosine tooth profile is presented in this paper.The first step is to generate an involute tooth profile by using an involute hobbing cutter.Secondly,a milling cutter is used to generate the cosine tooth profile on a three-axis NC milling machine.The generation principle of the cosine tooth profile is analyzed.The mathematical model of the minimum modulus using in the first step is established.The motion controlling model of generation of three-aixs NC milling machine is obtained.The simulation results of the machining process,obtained by the software Matlab,demonstrate its feasibility to manufacture the cosine tooth profile.国家自然科学基金(50975242);福建省自然科学基金(2009J01268);厦门市科技计划项目(3502Z20093038);福建省教育厅项目(JB11175)资
