Bioprosthetic heart valve consists of valvular leaflets, supporting stent and sutural ring valvular leaflets made with polymer materials of porcine or bovine pericardial can be opened or closed by ejected blood. [4].Its flow pattern is central-like.
For rigid stent material, displacement vectors of every point in brim of a leaflet are zero, so the boundary condition can be expressed as: {δ} = { u , v , w , Qx , Qy , Qz }T = {0, 0, 0 , 0 , 0, 0}T In this paper, we use 35, 50, 100 suture points on the attachment edge to stand for different suture points and the displacement vectors of every point is zero.

If preexisting cracks in materials are small, then the stress can reach the level required to initiate slip or twinning.
The shortest interatomic distances, assessed for materials with face-centered cubic (FCC) structures, are found to be smaller than that assessed for BCC ones.
The yield stress dependence on the temperature is low for FCC materials, therefore these materials can be used in cryogenic conditions.
For strain localization problems, the acoustic tensor method can be applied to only strain softening materials.

Continuing interest in the use of more highly wear-resistant materials in other engine-related parts has led to recent applications such as roller-type valve rocker arms, valve lifters and rocker arm alloys.

Although resin materials have been usually used for a core substrate of the PWB, glass is expected to be used for the core substrate in order to miniaturize wiring and reduce the material cost [2].
Furthermore, in the glass substrate that uses glass for a core substrate, the difference of the coefficient of thermal expansion (CTE) between glass and other substrate materials such as wiring and insulation resin exists.

The benefit of this technology can be presented in the following two aspects: 1) reducing nutrients loading and making wastewater treatment plants easier to reach the required stringent discharge standard [2]; 2) making use of struvite, which serves as a slow release fertilizer for agriculture or a raw material for phosphate industry [3].

As a new branch of accounting, environmental accounting regards the sustainable development as its thinking, promotes the rational allocation of resources, and finally maximize the social benefits by drawing on environmental economics, environmental science and other related disciplinary approach and according to the related environmental laws and regulations.
Compared with western developed countries, there are few companies that expose environmental reports, and they keep a low status in the aspect of publishing environmental material.
However, under the conditions of low-carbon economy, the accounting content of environmental accounting should focus on the expansion of the following aspects: low carbon assets should include the specialized equipment or premises for energy use and savings and raw materials, low-carbon technologies for low-carbon development; low-carbon liabilities should include the long-term and short-term loans, environmental protection costs payable and resource tax payable; low-carbon equity should include corporate-owned clean energy, low-carbon capital, energy conservation fund ,etc; low-carbon cost, the cost for the low-carbon development in economic activities, should include environmental protection expenses, compensation expenses, depreciation of fixed assets such as carbon; low-carbon profits should reflect the profits of company’s developing low-carbon economy.

Abstract.
Most DSSCs utilize nanocrystalline TiO2 as the photoelectrode, however, ZnO has proven to be a promising alternative photoelectrode material owing to its nearly band gap (3.37 eV) and comparable electron injection process as that of TiO2.

Analysis on arc fault mechanism
In electric circuit,arc fault modes include series and parallel.There are two reasons about series arc fault.On the one hand,vibration causes poor contact or fracture between the electrodes in order that intermittent arc is taken place[1].It is called as point contact series arc fault.The combustion from intermittent arc lead to conductor overheating,finally ignite the outer insulation materials of conductor.
