促进循环经济科学发展的若干思考

促进循环经济发展是贯彻落实科学发展观的需要,是实现经济增长方式根本性转变的重要途径。促进循环经济发展必须强化＂减量化优先＂的原则,必须健全相应的发展规划和制度,必须健全配套措施,切实推进各项工作落实到位。     

核壳橡胶粒子低温增韧环氧树脂的研究

本文采用具有核壳结构的橡胶(Core-shell Rubber,CSR)粒子低温增韧环氧树脂.研究表明,添加质量分数为0.5wt%的CSR粒子可明显改善环氧树脂的低温冲击性能;随着CSR粒子质量分数的增加,复合材料的玻璃化转变温度降低,但低温下的储能模量显著提高.形貌分析表明,质量分数为0.5wt%的CSR粒子可均匀分散在环氧树脂基体中,随着CSR粒子质量分数的增加,其在环氧树脂基体中呈团聚状分散.     

浅谈高职高专英语视听说课程替代英语基础课程的可能性

随着中国经济的发展,和外国的合作越来越多,这就加大了对英语人才的需求。但是基础英语教学过于注重知识(尤其是语法知识)的传授,轻视语言能力的培养。导致了经过十多年的学习后,中国学生还是听不懂、说不出英语,不能适应我国经济建设和社会发展的需要。因此,英语必须调整课程与教学计划,以培养学生的交际能力为目的。这不仅得到了理论支持,甚至各方面的条件的成熟都将支持这一变革。     

以三价铁为铁源制备高密度FePO_4粉体

将不同三价铁盐和合成工艺来制备高密度FePO4前驱体,分别从反应物浓度、终点pH值、以及干燥方式等因素对密度的影响进行了分析,得出了最佳工艺合成条件.实验结果表明：当温度保持在50℃,Fe（NO3）3.9H2O浓度为1.1mol/L,并且控制pH值=1.3,采用二次干燥工艺,可得到密度为1.55g/cm3锂离子正极材料前驱体FePO4.     

从《庄子》的神话思维看庄子的循环变化思想

庄子是中国古代思想家中最善运用神话的人。《庄子》一书气势磅礴,汪洋恣肆,将其独特的道家思想蕴于神话之中,通过运用神话阐释他心中的循环变化思想。从鲲与鹏,庄周与蝶,种有几,混沌之死,瓠与瓢等5个神话可以看出庄子独特的内心世界。庄子以其特有的神话思维方式,气象万千的想象力,影响着中国文化。     

Teaching and Learning about Language Change (Part One)

With particular reference to recent developments (including some in communication‐technology), this first of two papers explores the nature of ‘language change’ – its kinds, mechanisms and effects – and some attitudes towards it. It then suggests a case for teaching and learning about language change (bearing in mind, particularly, students in the 11–16 age range). The second paper, which will appear in Changing English 18:2, suggests approaches of two broad kinds and contexts: (1) as opportunities arise in undertaking other work; and (2) within planned, ‘set‐piece’ activities. Extensive notes/references are offered as support to teachers.     

Gender Adeptness Among Educational Administrators for Leading Innovative Initiatives in Public Education

It may be concluded that female administrators are perceived as being more adept than their male counterparts for leading innovation in schools and leveraging resources into productive outputs. It may be concluded that both genders of administrators perceive such efforts similarly. The only two skills where gender is significant are the two eornpetencies identified as being alert for new opportunities and synthesizing ideas into focused projects. For the other eight skills indicated in the survey, gender did not play a significant role in such perceptions.     

颜填料对不饱和聚酯树脂及原子灰固化的影响

考察和比较了一系列的原子灰颜填料的作用和功能及对原子灰固化的影响，发现重晶石粉料对不饱和聚酯树腊及原子灰的固化有明显的影响。     

试论合同法中的情事变更原则

情事变更原则是在民商事活动中以诚实信用原则为基础逐渐演绎出来的，其在适用条件、法律效力方面不同于不可抗力、显失公平和商业风险，虽然没有被写进我国的新《合同法》，但它已逐渐被其他许多国家的民商事立法所确认，成为一项较为基本的民商事活动原则。
