Then, high-speed grinding experiment was carried out to three kinds of metal materials, and machined surface roughness and surface hardness after processing are measured and researched.
Test shows that “speed effect” is remarkable in grinding metal materials.

There are many techniques to produce these silica materials, including supercritical drying, sol gel method, vapor-phase reaction and thermal decomposition technique.
Among these methods, the sol-gel method is a convenient and economic process for the synthesis of silica materials.

Introduction When the reinforced earth retaining structure in the alternating stress, due to  the occurrence of certain material permanent deformation localized, such as materials  yielding, plastic deformation of reinforced earth and the final fracture of material, which  customarily known as fatigue damage.
When it changes to a certain extent, the materials they will lose the ability to resist fatigue, resulting in fatigue failure.
