Abstract.
Micro vascular size is smaller, and also includes material transfer, exchange and chemical composition and the role of electric charge.
Fig. 1 2-D erythrocyte model and local finite element mesh enlargement Fig. 2 2-D computation sketch map of under shear flow t=0.0 s t=0.064 s t=0.128 s t=0.128 s t=0.128 s t=0.128 s t=0.128 s t=0.128 s Fig. 3 2-D movement of the erythrocyte under shear flow Fig.4 Contour map of flow velocity of the erythrocyte stability movement As can be seen from Figure 3, the central sunken of the erythrocyte membrane is more apparent in the initial stage, but as time goes on, the center sunken of the film gradually disappear, and at last the erythrocyte membrane becomes elongated spheroid; Meanwhile, we mark a bit of erythrocyte membrane with a red dot, "tank Crawler" movement of the erythrocyte membrane under shear flow can be seen in Fig.3, "Tank crawler movement" of membrane is propitious to the material transfer, and the moving speed also reflect the main mechanical properties of the film.

One of the essential tasks for cell fabrication is the surface texturing to reduce the reflection loss of silicon solar cells in the interface of the silicon material and surrounding materials [1].
The quartz material is selected as the CGH substrate due to avoid the surface structure damaged under the condition of high power laser beam incidence.
The refractive index of quartz material is 1.49 at the wavelength of 532 nm.

Li Gengying of Shantou University made a new interface agent with fly ash and sand as modified material [5,6]: cement ratio is 0.4, ratio of cement and sand is 1, pulverized fly ash is 15% of cement, adding moderate surfactant.
At the same time the functional layer material of PCC surface was DB-1 emulsion, in consideration of the matching of PCC and interface adhesive material, therefore, butadiene DB-1 polymer latex was as selected interface agent.
When horizontal pouring, splitting tensile strength of concrete of 28 days was about 2.96 MPa, and when the lateral pouring, its 28 days splitting tensile bond strength was 2.72 MPa, it was significantly higher than the samples of non-doped and other interface agent, indicating that interface roughness and the appropriate interface agent made two materials( RCC and PCC ) bond closely and work well.

Under such conditions the heat source and the molten metal under the heat source are fixed in space , and the material enters and leaves the computational domain by the welding velocity (Fig. 1).
The reference properties of the material of the molten zone are given in Table (1).
At other surfaces the enthalpy of the material is taken as the enthalpy corresponding to the room temperature.
