Concrete mixing time is the time from all raw materials into the mixing barrel to discharge [2].
When the filling rate is too large, the boiling effect of mixture reduces, causing materials flow not free and affecting the mixing quality.

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.

Numerical simulation method can not only save a lot of manpower and material resources, but also can solve difficulties to fatigue test for large or complex welded joints in the laboratory.
Actual stress method establishes fatigue damage parameter based on actual stress field of welded joints, uses stress-life curve of material as damage criterion, and finally predicts fatigue life [3].

localization.Because of these properties,we can produce a lot of excellent photoelectronic devices.These devices have been extensive uses.But when we introduce defect in the photonic crystal structure,we can get the better properties.Through introduce defect in photonic crystal,the defect mode will appear in photonic band gap.The frequency of photon what is the same of the defect mode is been confined the area of defect,others frequency of photo energy rapid attenuation.In this way,we can control transmission of the photon of the different frequency.Not only photonic crystal has this excellent property,and photonic quasicrystal also has.As everyone knows,the special construction of the photonic quasicrystal makes it has some excellent property,for example,it has the low index threshold when appear complete photon band gap[3];the photon band gap has nothing to do with direction;it has a lot kinds of defect modes.These excellent properties makes it become superior candidate object in photon band gap materials
and negative refraction materials,so the photonic quasicrystal has a wider application prospect.
Use two kinds of diamonds which they have same Length of a side and different interior angle proceed split joint,then put dielectric cylinders in the apex angle location of the diamonds.In this ten-fold photonic quasicrystal structure,the background material is air,the refractive index of the dielectric cylinders is n=3,the lattice constant and Length of a side is a=1mm,the radius of the dielectric cylinders is r=0.24a.From the Figure1,we can observe the ten-fold photonic quasicrystal structure model.
