电力建设研究所最近安装一台日本日立公司制造的S-450型扫描显微镜,经过中、日双方伎术人员共同调试,目前该仪器已投入运行,开始接受电力生产和建设中的试验研究任务。根据该装置的特点,它适于专题研究和事故分析,特别适用于金属结构件的断裂分析研究,如锅炉爆管,轴类的断裂等。扫描电子显微镜(SEM)是本世纪六十年代中期发展起来的大型精密仪器。除了观察物质的微观形貌和分析物质的微观结构之外,配有x射线能谱仪和x射线波长谱仪,可以定性和定量地分析微区的化学成分,从而获得微区的结构、形貌和成分的综合情况。因此,它是目前应用范围最广,颇受重视的分析仪器之一。
Recently, the Institute of Electric Power Construction installed a S-450 scanning microscope made by Hitachi, Japan. After the joint commissioning by technicians from China and Japan, the instrument has been put into operation and began to receive experimental research in power generation and construction. According to the characteristics of the device, it is suitable for thematic research and accident analysis, especially for the fracture analysis of metal structural parts, such as the boiler tube explosion, shaft fracture. Scanning electron microscopy (SEM) is a large precision instrument developed in the mid-1960s. In addition to observing the microscopic topography of the material and the microscopic structure of the analyte, an x-ray spectrometer and an x-ray wavelength spectrometer can be used to qualitatively and quantitatively analyze the chemical composition of the microdomains so as to obtain the structure of the microdomains. Appearance and composition of the situation. Therefore, it is currently one of the most widely used and highly valued analytical instruments.
