摘要:

大型仪器分析实验具有独特的地位和属性,实验过程更接近于实际分析工作,有利于学生仪器分析综合能力的培养。然而,传统方式无法实现大型仪器分析实验教学,而虚拟仿真技术虽然解决了一些问题,却也造成学生对虚拟平台和仪器实物的认知和操作偏差。本文以透射电子显微镜实验为例,探讨了如何在实验教学中将虚拟仿真技术与仪器实物教学有效地衔接,通过虚实结合最大程度地培养学生的大型仪器分析综合能力。

Abstract:

Large-scale instrumental analysis experiment has a unique position and attributes. The experimental procedure is closer to the actual analysis work, cultivating students' comprehensive ability of instrumental analysis. However, traditional approach can not realize the experiment teaching of large-scale instrumental analysis. Although the virtual simulation technology has solved some problems, it also causes the deviation between the virtual platform and the actual instrument. Taking the transmission electron microscope experiment as an example, this paper discusses how to effectively connect the virtual simulation technology with the teaching of actual instrument, and cultivate the students' comprehensive ability through the combination of virtual and actual teaching mode.

Key words: Large-scale instrumental analysis, Transmission electron microscope, Virtual simulation, Experiment teaching reform
