Field emission scanning electron microscopy(FESEM) and energy dispersive X-ray spectrometry(EDX) were used to obtain the morphology,number-size distribution and chemical compositions of individual mineral particles collected during the two dust storm episodes in April 2005 in Beijing.

The crystals from the experiment were measured by scanning electron microscopy (SEM) to confirm the influence of these factors.

The structure was characterized with scanning electron microscopy, high resolution transmission electron microscopy, and electron diffraction pattern.

Obsevation for Surface Structure of Nostoc sphaeroides Kutzing under Scanning Electron Microscope

S_2-4 were prepared, and their microenvironmental changes in the process of COD- removing from contaminated surface water were studied by scanning electron microscope (SEM).

Scanning electron microscope investigated the morphology of support,supported catalysts and polyethylene particles.

The paper introduces principle of scanning electronic microscope briefly; illust rates its applications of structure, nano size and ferroelectric domain taking e xample for ferroelectric ceramic materials; and explains its developmental tende ncy in combined functions with other instruments and several general questions i n scanning electronic microscope analysis of ceramic materials.

Briefly introduces the observation of the formation process of scraps of easy cutting steel by scanning electronic microscope,and analyzes effect of metal impurity on crackle when the scraps are formed.

With the help of an optical microscope and a scanning electronic microscope conducted are the detailed observations of the microscopic state change relationship of a Jiafu pulverized coal combustion process.
