摘　　要：材料的微观结构是研制、开发新材料,评价材料性能以及可靠性的重要因素。电子显微分析(如TEM,SEM等)是一类直接观察材料微观结构的实验方法。对材料微观结构测试结果的精确性和可靠程度的鉴别一直是电镜测试和大型仪器实验教学面临的问题。为此结合参与国际标准制定的工作经验,基于国际/国家相关标准的具体案例,依据现有的实验教学大纲,改进并创新了电子显微分析实验教学内容,建立了以国际/国家标准内容为基准的实验教学流程,在实验教学中培养学生对标准化的认识与应用,提升电子显微分析实验教学水平,同时为大型仪器设备使用、开放与共享提供技术保障。The microstructure of materials is an important factor in the development of new materials and the evaluation of the performance and reliability of a material. Micro-electron analysis（ e. g. TEM,SEM） is a classic experimental method to observe the microstructure of a material directly. The accuracy and reliability of the microstructure by TEM or SEM has been a problem in the field of electron microscope test and the experiment teaching of large instruments.National Exemplary Center for experimental teaching of material science improved and innovated the experiment teaching based on corresponding international and national standards by combining with practical experience in ISO,in order to improve understanding to concept of standardization. We established course of the experimental teaching by combining with the corresponding international and national standards,which provide technical support for the sharing operation mode of large-scale instrument and equipment and improve level of the experiment teaching for electron microscopy.
