现代汉语转折复句的语义基础

现代汉语转折复句主要可分为四种语义类型：并转、递转、承转和理转,其语义基础分别为并列、递进、顺承和因果。四种语义类型在能否还原上有差异：在一定的前提下,并转、递转和承转均可相应地还原为并列、递进和顺承复句,而理转通常不能还原为因果复句。理转是现代汉语转折复句的核心。     

大学教师教学发展的困境与对策：信息化与学习科学的视角——兼论校本教学发展的组织与制度

在信息社会和大科学时代,大学教学受到学生群体的变化和结构的多样性、信息技术的广泛应用、科研与教学的断裂等多方面的冲击。多学科视角下的学习科学对大学教师的教学专业能力亦形成挑战,教学发展的校本支持服务体系有待建设和完善。大学应从设置专业的教学发展支持机构和建设教学发展共同体两方面确保教学发展的组织归属,从奖励优秀教学、制订常态化的教学发展规划、职称评定中充分考虑大学教师的教学绩效等三方面,创设清晰的教学发展的制度导向;并应基于学习科学的理念,超越信息技术整合教学能力的培训范式,引领教师走出信息技术使用的唯PowerPoint误区,创设教师教学发展的虚拟学习网络。     

试析高职学生参与学生管理

高等职业教育作为普通高等教育的一个不可分割的重要类型,高职学生应同普通高校学生一样享有参与高校管理的权力。从学生参与管理的视角去分析目前高职学生参与学生管理存在的问题、成因并探索出解决问题的途径,增强高职学生参与意识,深化高职学生管理体制改革。     

中世纪大学学术职业:信仰与理性的统一

学术职业其本真就是信仰与理性的统一,溯其根源可追踪到中世纪.中世纪是一个唯信仰的时代,面对这样的身不由己,中世纪大学学术职业对信仰充满着热情,用其独特的方式守护信仰.然而这种热情并不是盲目的尊崇,而是带着希望激情,那就是用理性去捍卫信仰,保持信仰与理性的平衡.这正是学术职业的真正价值所在.正因为这样,使得中世纪的大学成为了后世一颗璀璨的启明星.     

论地方大学在区域文化发展中的作用

区域文化的建设与发展对于地方社会的发展具有重要意义,大学是文化传承与创新的平台,应当发挥自身文化职能,主动服务于区域文化建设。地方大学可以通过发挥文化传承功能,培养区域文化传承人才;通过发挥文化创造功能,开展区域文化研究与交流;通过加强校园文化建设,发挥文化示范与辐射功能,多层面地推动区域文化的繁荣与发展。     

从终身教育的角度审视现行自学考试助学教育的质量评价

高等教育自学考试是一种考试形式,也是一种教育制度,自学考试的定位已经逐渐从补偿教育、补充教育转向继续教育和终身教育,并实现了学历教育和非学历教育并重的发展格局。在当前形势下,自学考试助学应由单一的达标考试教育向全面素质教育的人才培养模式转变,以终身教育思想促进自学考试助学人才培养的结构体系转变,构建科学合理的自学考试助学教育质量评价体系。     

Improved response surface method for anti-slide reliability analysis of gravity dam based on weighted regression

The aim of this study was to design and construct an improved response surface method （RSM） based on weighted regression for the anti-slide reliability analysis of concrete gravity dam. The limitation and lacuna of the traditional RSM were briefly analyzed. Firstly, based on small experimental points, research was devoted to an improved RSM with singular value decomposition techniques. Then, the method was used on the basis of weighted regression and deviation coefficient correction to reduce iteration times and experimental points and improve the calculation method of checking point. Finally, a test example was given to verify this method. Compared with other conventional algorithms, this method has some strong advantages： this algorithm not only saves the arithmetic operations but also greatly enhances the calculation efficiency and the storage efficiency.     

HNCO hydrolysis performance in urea-water solution thermohydrolysis process with and without catalysts

The thermolysis of urea-water solution and its product, HNCO hydrolysis is investigated in a dual-reactor system. For the thermal decomposition below about 1073 K, the main products are ammonia (NH3) and isocyanic acid (HNCO) whereas at higher temperatures the oxidation processes take effect and the products include a low concentration of nitric oxide (NO) and nitrous oxide (N2O). The gas HNCO is quite stable and a high yield of HNCO is observed. The ratio of NH3 to HNCO increases from approximately 1.2 to 1.7 with the temperature. The chemical analysis shows that H radical is in favor of HNCO hydrolysis by instigating the reaction HNCO+H·→·NH2+CO and high temperature has positive effect on H radical. The hydrolysis of HNCO over an alumina catalyst made using a sol-gel process (designated as γ-Al2O3) is investigated. The conversion of HNCO is high even at the high space velocities (6×105 h-1) and low temperatures (393–673 K) in the tests with catalysts, which enhances HNCO hydrolysis and raises the ratio of NH3 to HNCO to approximately 100. The pure γ-Al2O3 shows a better catalytic performance than CuO/γ-Al2O3. The addition of CuO not only reduces the surface area but also decreases the Lewis acid sites which are recognized to have a positive effect on the catalytic activity. The apparent activation energy of the hydrolysis reaction amounts to about 25 kJ/mol in 393–473 K while 13 kJ/mol over 473 K. The overall hydrolysis reaction rate on catalysts is mainly determined by external and internal mass-transfer limitations.
