Introduction Because of small proportion, high temperature resistance and corrosion resistance of titanium alloy ,it has a good thermal stability in the following 500 ℃,in addition ,our country has a lot of titanium resources, therefore, titanium alloys have been widely used in aircraft rockets, satellites, tanks, submarines and precise instruments [1,2] However, because some of the specially physical, mechanical properties of titanium alloy, resulting in grinding titanium alloy difficultly, melting point of titanium alloy is up to 1725 ℃, the thermal conductivity is only 1/4 to aluminum, 1/5 to steel, but titanium alloys have high friction coefficient.
In this way, it will produce a large number of grinding heat in the grinding process, but the grinding heat cannot spread rapidly from grinding zone, it leads to have high temperature in grinding zone, then there is grinding burn in work piece, thus it will seriously affect the quality of the surface of the work piece.

Highly Conductive and Transparent PEDOT/PSS Thin Films with Large Area Prepared by Bar-coating Method Juan Li, Xiao-li Zhao and Hu Yana College of Chemistry and Molecular Engineering, Zhengzhou University, 100 Kexue Road, Zhengzhou 450001, China ayanhu@zzu.edu.cn Keyword: Conducting polymer; PEDOT/PSS; Halloysite nanotube; Hybrid film; Mechanical property Abstract.
For instance, aggregation of PEDOT/PSS particles would occur by the centrifugal force during spin coating, resulting in heterogeneous films with the variation of optical/electronic properties, which make spin-coating an inadaptable method for preparation of large-area PEDOT/PSS thin films.
As previously reported by Ouyang et al. [28], the gap size and the concentration of the polymer solution were the main factors determining the final thickness of the film.
The viscosity of the polymer solution and the final heating directly affected the uniformity of the film.
However, the thickness and the uniformity of the film were not affected by motor rotation speed.

Magnetic steel sheets with more suitable magnetic and mechanical properties are needed to prevent global warming.
The soft magnetic property of Si steel sheets is improved by increasing the Si content [1, 2].
This indicates that deformation-twinning behavior affects the stress–strain relationship.
This means that an additional microstructural factor should be considered.
(4) It is believed that the stress concentration, due to piled-up dislocations, during tensile deformation, significantly affects deformation twinning and brittle fracture.

Introduction Diamond, as a functional material, bears the unique properties, such as high thermal conductivity, chemical stability and mechanical strength, large forbidden band gap and high charge mobility.
Now, it is clearly known that doping diamond with some impurities, such as sulfur, boron, phosphorus, can vary some properties of diamond [1-3].
Nitrogen impurities are the most common impurities in diamond crystals, and doping nitrogen impurities in diamond lattice can also significantly affect its optical, mechanical property and thermal stability.
The concentrations of nitrogen in the form of A-center (NA) and C-center (NC) were calculated from the absorption coefficient which were multiplied by converting factor of 16.5 ppm/(cm-1) and 25 ppm/(cm-1) at 1282 cm-1 and 1130 cm-1, respectively , after the spectra decomposed into two individual components using the procedure described in Ref. [7].
ST and SP are atomic sensitivity factors for P2p and N1s spectra, respectively.

Cost plan, as it was, is a form of the target cost. 1.3The cost control Cost control is to point to in the construction process, the factors which influence the construction cost management, and take various effective measures, will actually happened in the construction of various consumption and expenditure strictly controlled within the scope of the cost plan, ready to reveal and timely feedback, whether accord with a standard strict censorship of various charges, to calculate the difference between actual cost and planned cost and is analyzed, and then take various measures to eliminate the construction waste phenomenon of the loss. 2.Completes the cost forecast, cost control target 2.1Engineering, material, cost prediction 1)First analysis of the project by the labor of the unit price, and then analysis of the workers' wages and social labor market, according to the time limit for a project and analysis of the number of people ready to put the project in the contract price
whether labor encase. 2)Materials proportion of take a fee, should be accurately as a focus, respectively, to advocate material, materials, auxiliary materials, other materials item by item analysis, the supply of the material location, purchase price, shipping and handling charges, analysis norm the materials specified in the specifications of different specifications and actual use of materials, comparing the actual USES the mixing ratio of cement dosage and the fixed amount differences, meta-analysis of the other materials of the budget, in the concrete practice to mix a certain amount of additive, etc. 3)Machinery use fee: bidding group model of mechanical equipment, number is generally adopts the norm to work out the construction method of a certain differences with the actual construction site, with the efficiency also have different, so to measure the actual machine disbursement is going to happen.
The main machinery shall be affecting production quota. 2.2Construction plan of the change of the cost forecast After the bid of the project, must be combined with the actual situation of the construction site to establish advanced technically feasible and the implementation of the economic and reasonable construction organization design, combined with the economic and natural geographical conditions of the project location, construction technology, equipment selection and arrangement of the actual situation of the time limit, more sexually shy group adopted by the construction method and the difference of bid preparation, or with the norm of different construction methods, as to make the correct prediction according to solid. 2.3The prediction of auxiliary construction cost Auxiliary refers to the bill of quantities of quantities or no given in the design drawings, and is indispensable in the construction, such as: concrete mixing station, the tunnel construction in the three tube
From the employment quantity control, targeted to reduce or shorten the man-days consumption of certain jobs, thereby reducing consumption of man-days, control engineering cost. 2)The material cost control Materials of general project total cost 65% ~ 75%, and directly affects project cost and economic benefits.
