The work in detail is that construction agent shall set up a special account of the project construction finance, the financial management department shall appropriate in installments to construction agent by the financial plan, and construction agent shall pay the capital to the main contractor, the engineer, the procurement contractor of plant and materials etc.
On the other hand, Construction agent shall sign the supervision commission contract, survey and design contract, construction contract and material procurement contract, which involve in extensive contents, complex cases such as the undefined scope of risk, the contradictions of contract and the two explanations of significations etc.
The contract clause should be ready seriously, avoid the hazard and the occurrence of engineering variations and claim for compensation, and decrease the limitation, while it is made for the contract of engineer, reconnaissance and design, construction and material stock.

DHM is a plant flavonoid, most commonly extracted from natural plant materials, such as the fruits of Hovenia dulcis (Yoo S M et al., 2006) and the leaves and stems of Chinese vine tea (Ampelopsis grossedentata) (Du Q et al., 2002; Zheng C et al, 2006).
Materials and Methods Chemicals and Reagents DHM (95%) was obtained from Fine Chemical Research Laboratory of Guanzhou University.

The main parameters which affect the simulation results are the friction coefficient μ and the material data.
Validation for carbide tools and titanium alloys In order to describe the material behaviour at high deformation rates, a new material model is used to take into account strain rate hardening, thermal-softening and strain-softening phenomena.

In this article, (NH4)2TiF6, SrNO3 and H3BO3 were used as raw materials to prepare the precursor solution with the ratio of AHFT/SN/BA=1:1:3.
The characteristics of reverse bistable polarization of the ferroelectric thin film materials with spontaneous polarization as the external electric field have been studied to develop ferroelectric storage with non-volatility, that is, the stored data still remain even if the electricity is cut off.
If these methods tend to prepare the nano film materials with the dense and homogenous structure, the controlled thickness and the higher crystallization, they need the special equipments, the complicated preparatory technology and the preparatory conditions of vacuum and higher temperature.
Using (NH4)2TiF6 (AHFT, chemical purity), Sr(NO3)3(SN, analytical purity) and H3BO3(BA, analytical purity) as the raw materials, the precursor solution was prepared with the ratio of AHFT/SN/BA=1:1:3.
