This paper presented a story-based stability design approach of frames,story-based slenderness is proposed and the stability coefficient is than based on the well-known column curves.

This resulted in columns appearing many bending and bending-cutting cracks.

Based on the example, the methods of strengthening design for column by entarging section is introduced in this paper, It can be taken as a refrence for other designs of strengthening.

Surface acidity of CLM probably originates from the pillars and its surface hydroxy.

Pillar works as the mostly important element of framework, which going through the whole history, such as stone pillar in Egypt, totem pole of Africa, wood class pillar in China, class order of Europe, steel pillar and reinforced concrete pillar in modern period .

Research on the motion of cylindrical particles in pneumatic conveying system;

The lattice Boltzmann method is used to simulate numerically the sedimentation of cylindrical particles in the wall-bound flow field.

Based on the numerical simulation of mixing layers, the motion equation of cylindrical particle is solved and the particle trajectories are given.

Principle of grinding spherical ends of cylindrical roller with generating method and roller convexity calculation anylysis;

Based on the non-linear characteristics of fractal theory,the surface profile of cylindrical rollers is studied.
