Accordingly, the dispensed liquids have been expanded from the conventional pigmented ink (or standard dye-based ink) to polymers , gels, cell ink or other materials which often have higher viscosities or even contain large particles or cells[7].
The selected material is brass, which has good conductivity.

In microscopic view of the TEM drilling, the material at beam-focused area was heated up due to direct electron bombardments and temperatures of the surrounding materials were raised up through heat conduction, with a negative temperature gradient radiated outward from the hottest focal spot.
Since the heat accumulation, a shallow melted pit centered at focal spot was created and the material underneath the melted pit was softened.
In theory, a straight through-pore would be more likely if we could reduce the size of the melted pit and the region of the material being softened.

The first two methods are the high cost of raw materials and post-processing complex.
This method is mainly can improve the content of rutile phase by adding promoter, but particles become large, and they are not taken into account material preheating and the reactor structure on particle morphology.
The structure of the film was determined by x-ray diffraction analysis using an XRD spectrometer(Japan Science and Electrical Rigakud/max-B) with Cu Ka radiation(40KV, 100mA).

Supply Chain is physical distribution, cash flow and information flow between related departments or business partners, and covers the whole process of product (or service) design, raw materials procurement, manufacturing, packaging, and pay the end user.
Generalized logistics management, includes material transformation process of the whole raw materials to product process, namely, supply chain management.

To solve the problem, silicon rods are usually cut into pieces through wire sawing technology, and the diamond wire saw cutting is one of the excellent machining tools .so far, the tool has been widely used for semiconductor materials’ fine finishing.
We also need to make two assumptions: (1) Bed is an invariant linear system, ignoring the damping effect. (2) Density of bed material is uniform, perfectly elastic bed.
The material of bed is HT300.Having inquired "Mechanical Design Handbook", we get the parameters: ρ = 7.3 × 103kg/m3, μ = 0.25, E = 1.25 × 105GPa.
Optimization From the analysis above, we put forward four kinds of optimization improvements: (1) Add damping material where vibration severely

Materials Use standard sand and artificial stone（the particle size of 10 to 40 mm），which is the raw materials of hardened concrete ，use benchmark cement as the cement of concrete ，The chemical composition is shown in table 1: Table 1Chemical composition of benchmark cement SiO2 Al2O3 Fe2O3 CaO MgO SO3 21.96 4.73 3.68 65.3 2.59 0.3 NaOeq f-CaO C3S C2S C3A C4AF 0.56 0.9 57.4 20.3 6.32 11.19 Experimental Methods Known as the preparation of w/c of hardened concrete :0.3,0.35,0.4,0.45,0.5, removed 3 in its reach 3d, 7d, 28d and 90d of the age respectively, the hardened concrete is cut into a cube of side length which is not more than 1cm with concrete cutting machines, after sanding on concrete sections in small cubes resin saturated with resin inlay instrument , the pores may be completely filled with epoxy resin ,after drying and polishing, the capillary in the resin saturated backscattered SEM photograph mode are displayed as black ,while other solid phases are bright.
If the types of raw material of this experiment change , it may need to use this test method to simulation analysis again.

However, understanding charge injection and the recombination process in organic materials is insufficient to explain the mechanism of OLED devices.
Two cathode materials were Ni and common metal Al.
