独立学院教学中的四忌

独立学院的学生与母体高校学生相比有一定的特殊性。独立学院的教学如若完全沿用母体高校的方法和要求,势必会出现一些问题和矛盾。为此,在独立学院教学中,教师应注意四忌。     

顽辉石陨石(EH、EL、Aub)的母体及其形成条件

通过对已知最还原的EH、EL群球粒陨石和AUb群无球位陨石的岩石矿物学对比研究，揭示了EH、EL群陨石母体之间在矿物模式组成和矿物化学组成上的异同性，并提出了EH群陨石母体相对于巴群形成于一个更加还原的星云条件的观点及论据。通过对不同岩石类型陨石样品的对比，还揭示了EH和EL群陨石母体的热变质过程伴随有还原反应的特点，并指出EL群陨石母体相对于EH群陨石具有较缓慢的冷却达率和更开放的体系特征。通过对AUb群陨石的研究，揭示了其矿物化学组成上的不均一性及其与EH和EL群陨石的明显差异，表明该群陨石至少有二个独立的母体，且还原程度分别接近或略低于EH和EL群陨石母体。     

太阳星云早期元素化学分馏

根据球粒陨石全岩组成、球位和碳质球粒陨石难熔包体的元素丰度分布特征揭示的陨石母体早期化学分怕的证据，论述了太阳星云条件下球粒陨石母体经历的化学分馏过程，难熔元素、亲铁元素和挥发性元素各自的化学分馆特征，这些特征保存了母体早期形成过程——凝聚阶段的信息，说明凝聚作用是太阳系原始行星母体经历的主要化学分馏作用过程。     

独立学院机械设计基础精品课程的探索与实践——以北京理工大学珠海学院为例

独立学院作为一种新型的高等教育模式的院校,以培养应用型、技术型人才为目标,建设有独立学院特色的精品课程是实现培养目标的重要手段之一。论文以北京理工大学珠海学院精品课程机械设计基础的建设为例,从该课程教学内容、教学手段等方面进行了探索与实践。     

独立学院“运筹学”教学改革的探讨

运筹学是工程管理、物流管理等专业的必修基础课程。传统运筹学教学中普遍存在重理论、轻应用的倾向。特别是在独立学院的教学中,运筹学是教学难点,学生普遍反映课程枯燥、内容艰深。因此需要对运筹学教学内容和教学方式的改革进行探讨。     

聘用制下独立学院教师绩效考核指标研究

构建合理、人性化的独立学院教师绩效考核与指标体系,并据此对独立学院聘用教师进行全面考核与评估,对考核结果进行反馈,可提高独立学院整体办学效能。结合实际工作,探讨构建独立学院聘用教师绩效考核与评估体系的制定,具有重要实际意义和参考价值。     

独立学院学生思想政治教育实效性研究

伴随着我国高等教育事业的不断推进,作为高等教育发展与变革的一种全新模式,独立学院对促进我国高等教育大众化的发展,具有极为重大且深远的意义。独立学院是高等教育中一个十分关键的构成部分。相对于普通高等学院的大学生而言,独立院校的学生具备一定的特殊性,例如家庭经济状况、心理发展情况等方面较为特殊。针对这情况,对独立学院的学生进行思想政治教育工作,是极为有必要的。文章将对独立学院思想政治教育工作中存在的问题进行分析,并提出有效的改善措施,以便最大限度地提升独立学院学生思想政治教育的实效性。     

不同母体制备的金属离子交换ZSM-5分子筛上C_3H_6选择催化还原NO反应的研究

 研究了由钠型及氢型ZSM-5母体制备的金属离子交换分子筛在过量氧存在下丙烯选择催化还原NO的反应。发现反应活性及活性温度范围取决于分子筛母体与金属离子的种类。在各种金属离子交换分子筛催化剂中，钴离子交换CoH－ZSM－5具有最高的活性，且随钴离子交换度的增加反应活性亦随之增加。     

酚类、醇类抑制斜生栅列藻生长的毒性效应

以生物监测方法，利用国际标准指示生物斜生栅列藻研究酚及其衍生物和丁醇其异构体的急性毒性规律。试验表明，苯酚衍生物的毒性比母体强得多，而后者的毒性比丁醇及异构体更大。     

清镇(EH_3)和某些其他顽火辉石球粒陨石硫化物的微量元素及其成因意义(摘要)

<正> 顽火辉石球粒陨石是一个具有异常化学和矿物组成的小陨石群,由于它们形成于异常的母体环境而表现出许多明显不同于其他球粒陨石群的特殊性质,例如,对它们的母体物质来源、形成区域、氧化还原条件、吸积温度、变质作用以及母体数目、与球粒陨石和无球粒陨石之间的成因联系等等,一直争论不休。     

用二氧化氯降解废水中的苯胺类化合物（1）COD去除规律的研究

用二氧化氯氧化降解８种苯胺类化合物，测定了ＣＯＤ去除率与时间及ＣＯＤ去除率与ＣｌＯ２用量之间的关系；结果表明最终的ＣＯＤ去除率多数都在７０％以上，羟基类苯胺化合物可达９０％以上．反应符合ｌｎＣＯＤ＝Ｋ１ＷＣｌＯ２＋Ａ１及ｌｎＣＯＤｔ＝Ｋ２ｔ＋Ａ关系式．ＣＯＤ去除率还与ｐＨ值的大小有一定的相关性．
