工程造价专业课程结构创新之项目全过程集成暨逆向教学法的理论与实践

工程造价专业是务实高效培养高素质技能型人才的应用技术型职业教育专业。传统教学模式按不同学期区分专业基础课和专业核心课,设置识图与施工工艺、计量与计价、软件应用的课程内容。在当前互联网+、BIM技术应用、装配式建筑推广等新兴技术条件下,应进行适宜性改革创新。文章采用"项目全过程集成暨逆向学习方法"(Project Whole Process Integration and Reverse Learning Method,简称PR集成式逆向教学法),主要是以全过程、模块化、集成式、逆向教学法为基础,按照"分部工程或子分部工程为对象"构建区分不同专业方向、全过程集成模式下的课程结构,PR集成式逆向教学法能更好地满足中国教育部提出的应用技术型职业教育应实现"产教融合、校企合作、工学结合、知行合一"四合要求。

Durability properties of concrete with blended cements

The study of chloride‐induced corrosion started more than three decades ago, after extensive cases of damage were observed on reinforced concrete structures in coastal regions and on infrastructural objects exposed to salt action. Nowadays, the basis for sustainable concrete industry lies in these three aspects: reducing CO₂ emissions by using by‐products of other industries (slag, fly ash, silica fume) for cement production, conservation of natural resources by replacing part of the aggregate with recycled construction waste, as well as use of recycled water in concrete production, and finally, construction of durable concrete structures. Durability design procedures for reinforced concrete structures in aggressive environments are still to a large extent empirical, especially in the case of using blended cements. The type of cement has a considerable effect on the properties of concrete, especially concrete resistance to the penetration of chloride ions. The paper presents results of testing durability and deformational properties of concrete produced with quaternary‐blended cement. A clearer insight into these properties is a necessary starting point for the performance‐based design of concrete prepared with blended cements, leading to more durable and corrosion‐free concrete structures in aggressive environments.     

A structured overview on the use of computational simulators for teaching statistical methods

Modern technology is affecting what is taught and how statistics is taught. Computer intensive methods like bootstrapping, generalized regression, coordinate exchange algorithms and computer experiment emulators are now part of the statistical toolkit. In parallel with these new methods and tools, a similar evolution appears in statistical education. Simulators offer opportunities for hands-on experience in the classroom, bridging the gap between theory and practice. In this article, we map a wide range of simulation based tools used in teaching statistical methods, putting them in the context of a quality ladder representing various maturity levels of organizations and course level sophistication. The mapping is designed to help educators assess and integrate options related to the incorporation of simulators as teaching aids in an educational and pedagogical roadmap. The mapping is applied to specific simulation products but provides a general framework that can be expanded and used in a generic way.

乙炔/甲烷预混燃烧合成碳纳米管的试验研究

采用乙炔和甲烷的混合气作为燃料,利用涂覆硝酸镍的铜基板,进行合成碳纳米管的试验研究。对于制备出的碳纳米材料的微观形貌采用扫描电镜(SEM)和透射电镜(TEM)进行了表征,分析了不同燃料对火焰合成的影响,并研究了硝酸镍催化剂的浓度对合成碳纳米管的影响。研究结果表明:利用两种混合气体预混燃烧能够成功合成出质量较好的多壁碳纳米管;采用浓度为0.01mol/L的硝酸镍催化剂无法合成出碳纳米管,只有碳纳米纤维等纳米材料。硝酸镍催化剂浓度为0.1和1.0mol/L时能合成形态和结构都较理想的碳纳米管。
