摘　　要：粉末X射线衍射仪是材料类专业非常重要的分析和表征仪器,仪器多为进口设备,价格高,结构复杂。无机材料物相分析实验是本科生实验教学的重要内容。线下利用粉末X射线衍射仪研究无机材料的晶体结构与物相,存在成本高、台数少、学生不能独立操作、灵活性差、操作时间与场地受限等问题,通过无机材料物相分析虚拟仿真实验教学平台能够很好地解决上述问题,有效拓展教学空间、拓宽教学内容、提升实验教学效果,增强学生的自主学习能力。Powder X-ray diffractometer is a very important analysis and characterization instrument of material major,and most of these instruments are imported equipment with high price and complex structure.But inorganic material phase analysis experiment is an important link of teaching activities.Powder x-ray diffraction instrument is used to study the crystal structure and material phase of inorganic materials offline,and there are problems such as high cost,low set rate,students’lack of independent operation,low flexibility,limited operation time and limited site,etc.Through the virtual simulation experiment teaching platform,the above problems can be well solved,effectively expand teaching space,broaden teaching content,improve experimental teaching effect,and enhance students’autonomous learning ability.
