TSS has also been successfully applied to other ceramics materials to produces ceramic bodies with small grain size [12-17].
As ceramic materials has no plastic deformation, if there is a propagating crack, the crack would propagates until fracture occurs since ceramics have no mechanism to absorb any energy transformed to the material.

Many products have the disadvantages, such as heavy, consuming more material and energy, especially for large-sized beam component.
This is to say, applied this system, the structure analysis and optimal can easily automatically complete, the results must also be lower heavy and realize the objects of save energy and materials.

Experiment materials and methods 2.1 Experiment materials The T23 material was taken as working electrode (WE), its cross-sectional area was 113.10mm2, the reference electrode (RE) was saturated calomel, the counter electrode (CE) was platinum electrode.
(3) By the experiment characterization on two kinds of materials and solutions, it showed that the Cl- concentration was bigger and the dissolution of iron was less after material was passivated.

At present, the optional materials of MEMS mechanism chiefly include silicon and metal.
Many scientific organizations have measured the property of LIGA nickel material, and it comes out that material property has big the parametric dispersibility and has notable difference with the traditional nickel material in the aspects of hardness, elastic strength and yield strength [3].
Under the effect of external environment stress, the material property may changes.

It is a common practice to remove material less than 10μm in size from tin concentrate feeds and direct this material to the tailings [2].
Preparation work for the beneficiation test was conducted according to the following procedu: firstly, 1-ton run-of-mine material was mixed completely, and then it was sampled into a 500-kg keepsample and a 500-kg testing material.
The 500kg material was ground to -2mm for laboratory tests, mineralogical study and other purposes.
Since Yunnan Tin Group accepts tin material grading 3% Sn above, for a higher recover of tin and simplifying the flowsheet, magnetic operation is not recommended.

Table 1 shows the main performance parameters of the frame material.
Table.1 The main performance parameters of the frame material Materials Density Yield limit EX PRXY Q235 0.078g/mm3 235MPa 210GPa 0.3 The establishment of finite element analysis geometric model of frame surface.This paper established the three-dimensional model of frame by SolidWorks software, the three-dimensional model of frame was done with some simplifications, such as pedals, battery rack, and other non-load parts were deleted, these simplifications reduced the workload, avoided the deformed grid to some extent, and improve overall computational accuracy [3].
Poisson's ratio and elastic modulus of frame was set in ANSYS environment; in addition, the weight of frame was a large proportion of towing machine and can not be ignored, so the density of material was defined.
