In this building, the traditional hollowing, the grain of ceramic and the brilliant red colour in Chinese traditional culture are blended in with the age's most advanced steel structure design in a perfect way.
Today, an increasing number of watch brands choose to expose the tuning part, the counterweight, and the balance wheel clearly.

The results of finite-element modeling and comparison with analytical solutions are presented in a number of papers [13, 14], whereas the results of boundary-element calculations in a 3D formulation are not covered in the literature.
Governing Equations The constitutive equations for a two-phase poroelastic medium according to Biot’s theory [15, 16] have the form: (1) , (2) , (3) where is total stress in the porous material, is deformation of the elastic skeleton, K and G are bulk moduli of the elastic skeleton, is bulk modulus of the skeleton grains, is bulk modulus of the filler, is porosity, is pore pressure, is displacement of the elastic skeleton, is displacement of the filler relative to the skeleton.

The concrete mixes marked as R3, R4, R5, and R6 contain aggregate grains of size ranges 0–4 mm, 0–8 mm, 0–16 mm, and 0–22 mm, respectively.
In this case, because of data evaluation limitations (AE scanning with insufficient number of sensors), only the AE data were recorded; however, provided with more advanced instrumentation and evaluation [5].

The wrought CoCrMo alloys exhibit superior mechanical and chemical properties compared with the cast alloys due to a finer grain size and more homogenous microstructure [6].
However, in order to have similar microstructure as natural bone, the number of closed pore should be minimized.

Third, wrote down the exact number of the volume, and the tapped density was the ratio of its mass to its volume.
However, when the concentration is too high, it will product more nuclei, and the nucleation rate is faster than its growth rate, and inhibit the growth of the nuclei, thus it leads to smaller grain size, more defective lattice, much disordered accumulation, and more amorphous components.

In this way, many common thermal spraying problems can be effectively reduced and eliminated, like oxidation, phase change, ingredients change, grain growth[5-10].
The figure 5 (b) shows that, in dry friction condition, the grinding mark in the coating material surface has obvious furrows, and there are a large number of slices of spalling pit.
