Selection of the Constituent Materials According to the above analysis, we select the constituent materials needed to prepare frost resistant and anti-corrosive concrete with strong endurance by using ordinary Portland cement.
The performance of each constituent material is as follows.
We select engineering application mixture proportion to prepare the concrete test piece and detect 56 days’ charge passed of the concrete to evaluate the chloridion’s permeability resistant performance.

Introduction Due to the high displacement threshold energy of atoms in SiC, one can expect that devices based on this material will exhibit high radiation hardness.
Variation of key electrical parameters, the threshold voltage VTH and the ON-State resistance RDS_ON, with the applied dose of electrons is Fig.2 Variation of the transfer characteristics ID=f(VGS)@VDS=50 mV of the 1700 V SiC power MOSFET C2M1000170D with applied dose of 4.5 MeV electrons (measured at 300K).

From the notability analysis of orthogonal experiment above, building area, building front orientation, shape ratio, area ratio of window to wall, heat transfer coefficient of exterior wall, machine heat and lighting heat are the main factors that have the most impact on building air conditioning energy consumption, and they are the key factors to control to achieve the goal of building energy efficiency, these factors should be fully considered in the process of architectural design with the consideration of building energy efficiency.

And the research on the entrepreneur or the family business focuses on the different key stages, the former on the start stage and the latter on the succession of trans-generation.
The factory has not been allowed to buy cotton material from the local farmers and collected the remnants of state-owned apparel enterprises.
This salesman returned to Cixi and determined to develop the part with the ten samples with the engineers.
Mao lost his vice manager, a few engineers and customers as well.

Abstract.
It can be said that the diffusion mechanism is one of key issues on the Cu precipitate formation.
It should be pointed out that, in the numerical simulation, we must take into account the density of the vacancy in the material.
