摘要：利用PHITS程序评价计算了厚靶^(9)Be(d,xn)反应加速器中子源的能谱和角分布数据,重点讨论了JQMD、INCL和INCL/DWBA三种核反应物理模型计算厚靶^(9)Be(d,xn)反应中子辐射场分布的适用性。研究结果显示,基于INCL/DWBA耦合模型的PHITS程序计算所得到的厚靶^(9)Be(d,xn)反应中子能谱和角分布数据能够较好地与实验数据符合,可以为厚靶^(9)Be(d,xn)反应中子源特性研究及应用提供较为准确的中子辐射场数据。此外,设计了水冷大面积旋转铍靶的方案,并在5~25 MeV/5 mA入射氘能量下条件下,开展了靶面温度模拟研究,结果显示,靶面最高温度可控制在100℃以下。

摘要：在“学生主体、成果导向”的OBE理念的指导下,探讨应用型高校“风景园林施工与管理专题”课程的教学模式。结合当前学科背景和教学需求,以培养学生工匠精神的专业素养为核心。从教学目标制定、课程体系建设、授课组织实施、成绩组成评定到教学效果评价,全面实现教学理念、教学体系和教学模式的优化。将传统教学转化成新型教学体系,为提升高质量教学、培养创新型高素质人才提供保障。Under the guidance of the OBE concept of “student-oriented and result-oriented”, the teaching mode of “Landscape Architecture Construction and Management Topic” in applied universities is discussed. Combined with the current discipline background and teaching needs, the core is to cultivate students’ professional quality of craftsman spirit. From the formulation of teaching objectives, the construction of curriculum system, the implementation of teaching organization, the evaluation of grade composition and the evaluation of teaching effect, the optimization of teaching concept, teaching system and teaching mode is fully realized. This teaching mode will transform traditional teaching into a new teaching system, and provide guarantee for improving high-quality teaching and cultivating innovative and high-quality talents.
