This paper mainly describes morphologic and physicochemical characteristics of cashmere and wool fibers,summarizes techniques of optical microscopic method,scanning electron microscope,solution analytical method,computer graphics analytical method and genes analytical method for the identification of cashmere and wool fibers.

The configuration parameters of UF surface pore size distribution, porosity and pore density were measured with scanning electron microscope (SEM), the field emission scanning electron microscope (FESEM) and permeability rate method.

Gypsum fibrosum and gypsum fibrosum preparatum by scanning electron microscopy;

The micro-structure changes of Gaomiaozi bentonite in the process of hydration,which is deemed as the best buffer or back-filling material for deep disposal of high radioactive waste in China are analyzed under unconfined and confined conditions by using mercury intrusion porosimetry(MIP)method and environmental scanning electronic microscopy(ESEM) techniques.
