本文从分析目前研学实践活动开展所存在的问题出发,提出将4F教学模式融入研学实践活动方案设计的优势,并以内蒙古集宁区霸王河国家湿地公园为例,确立基于地理学科核心素养的研学目标,依据4F教学模式的四个阶段设计研学活动实施过程,同时制定了基于4F模式的评价量表,对学生的研学过程与研学结果进行全方位多角度评价,以期提高研学效果,为相关研究者和一线地理教师更好地设计基于4F模式的研学实践活动方案提供参考。Based on the analysis of the existing problems in the development of current research practice activities, this paper proposes the advantages of integrating 4F teaching mode into the design of research practice activities. Taking Bawanghe National Wetland Park in Jining District, Inner Mongolia as an example, this paper establishes research objectives based on the core accomplishment of geography, and designs the implementation process of research activities according to the four stages of 4F teaching mode. At the same time, an evaluation scale based on 4F model is developed to evaluate students’ research process and research results from a comprehensive and multi-angle, in order to improve the research effect and provide references for relevant researchers and front-line geography teachers to better design research practice activities based on 4F model.

地热能是可再生能源之一,而地源热泵系统是应用地热能的一种重要方式。为提升工作效率,基于Visual Studio 2022开发平台,以C#编程语言下的WPF框架开发了一款地源热泵多能耦合系统方案设计软件,并依托于某项目对该软件在实际工程中的可用性、准确性进行了验证。该软件运行结果表明选用2台某地源热泵机组及5台某空气源热泵机组可承担该项目冷热负荷,每年耗能为4347.36MWh,总能耗费用449.53万元,单平米能耗费用33.30元/m^(2),在得到特定比例补贴的情况下投资成本总计3545.92万元,单平米造价262.66元/m^(2),与原设计方案一致。
