【摘要】 我国利用扫描电子显微镜研究黄土微结构的报道始于20世纪的70年代。随着当代电子技术和计算机的发展,利用扫描电子显微镜和能谱分析技术,可以在观测微结构的同时,实现对微结构元素分析的目的。本研究介绍了扫描电子显微镜和能谱分析技术的原理,并从样品制作、处理、观察和结果分析等角度就二者在黄土微结构研究上的应用做了探讨。更多还原

【Abstract】 Applying scanning electron microscope(SEM) on the study of loess microstructure was started in the 70th of the last century in China. Along with the development of electron and computer technology, we can observe the microstructure of soil and analyzes the elements in the microstructure by SEM and X-ray energy dispersive microanalysis(EDX,EDS)EDX. This paper introduces the principle of SEM and EDX, and discusses the application of both on the study of loess microstructure from the making, treating,obsering and result analyzing of sample.更多还原
