Moreover, it has the lighter weight, saves the material and decreases earthquake function contrast to the general shear wall.
Both the 22 commercial building in Fuxin and the 20 commercial building in Benxi apply ceramsite concrete short pier shear wall [8].At present, our country takes the technical measures to conserve energy mainly through the traditional wall materials which brings a series of difficult questions.

Basing on isotropic material and taking the relative density of materials as design variable, SIMP approach with high efficiency is easy to be realized by program.
In other words, the iterating results under the control of local rule will ultimately determine the distribution of materials in the design domain.
(2) The distribution of solid materials in design domain through iterative process is controlled by the local rule.

Λ value of the new super-magnetostrictive material is large, compared with traditional materials to two orders of magnitude or more.
From traditional materials of 10 ~ 100ppm up to 1000~2500ppm, which is a breakthrough[2, 3, 4].

Flame retardanct effects of Magnesium Hydroxide Magnesium hydroxide shows the flame retardant effect with decomposing and absorbing surface heat from polymer materials when heated.
Zhang et.al[14] synthesized fibrous magnesium hydroxide by chemical precipitation method and subsequent hydrothermal synthesis method, which used magnesium chloride and ammon as starting materials to synthesis the precursor, basic magnesium chloride, then magnesium hydroxide was gained with a fibrous crystal structure and has an aspect ratio of 30 and an average length of 150μm.
Develop exclusive surface modification agent suitable for different polymer materials, especially increasing research on compound modifier.

While, due to the very short interaction time between laser and material, the material erosion mechanism and simulation are still in the research.
The model after the material removal is shown in Fig.4.
