In the present paper,it was find that the etch pit pattern's on (111)surfaces of CZT(Cd_(1-x)Zn_xTe)crystal exist all the geometric characters of Sierpinski gasket(triangle)we as-sume a etching potential of defection the cryustal to explain the phenomena.

Effect of AOD Oxidizing Slag on Magnesia-Calcia Lining Erosion;

Numerical simulation of erosion for carbon-based composites impacted by hypervelocity particles;

Theoretical analysis about erosion of refractory by slag which produced from new shaft furnace technology for smelting chrome iron;

Properties of cement-based material mixed with grounded slag powder due to sulfate attack at low pH value;

Study on Resistance to Sulfate Attack on Mortar Containing Mineral Admixture;

Based on katogene mechanism of acid rain attacking concrete,the simulation test of the acid rain attacking concrete was analyzed by the shower-lighten cycle method,which sets up its parameters,including the pH value and ion concentration of the liquor, rainfall,temperature and temperature difference,humidity under alternating between dry and humid etc.
