虚拟仿真实验作为大型仪器分析实验教学模式的新兴趋势,有效地将虚拟仿真技术与实物仪器教学相结合,最大限度地提升了学生对于大型仪器分析的综合应用能力.本文以激光诱导击穿光谱(LIBS)虚拟仿真实验系统为例,完整地模拟了LIBS系统的样品处理、光谱采集、定性分析和定量分析等实际实验场景,通过虚实结合实验教学模式对实验过程进行实时跟踪与综合考评.该实验有助于提高学生自主探究能力和创新意识,培养具有独立思考与实践能力的拔尖人才.
Virtual Simulation Experiment for Laser-Induced Breakdown Spectroscopy (LIBS) Analysis
Virtual simulation experiments represent an emerging trend in the pedagogical approach to teaching large-scale instrument analysis,effectively integrating virtual simulation technology with hands-on instrument training to maximize students' comprehensive application skills in large-scale instrument analysis. This paper focuses on a virtual simulation system for laser-induced breakdown spectroscopy (LIBS),meticulously simulating the entire LIBS experimental procedure,including sample preparation,spectrum acquisition,qualitative and quantitative analysis. Through a blended learning model that combines virtual and physical experiments,the process facilitates real-time monitoring and comprehensive assessment of student performance. This approach not only enhances students' independent inquiry ability and innovative consciousness,but also aims to cultivate top-notch talents with independent thinking and practical abilities.
