The Guarantee Rate of the Engineering is not Unified.
Bank is the largest engineering guarantee market guarantor, almost a monopoly of our country engineering guarantee market all the volume of business.
Recommended by the construction administrative departments take the lead in establishing the database to achieve longitudinal (mainly the construction administrative departments between) and lateral (industry and commerce, taxation and other departments) networking, as far as possible to the engineering guarantee subject provide the contractor and the owner of various materials, the contractor and the owner 's credit level to make accurate judgments.
Engineering guarantee is directly to the engineering services, the fees shall be included in the cost of the project, at the national and local engineering cost management, should be studied to solve the problems in the cost of the project.
Research of Chinese engineering assured guarantees mechanism.

Therefore, some related subjects were studied in this paper by experiments, theoretical calculation and engineering practice.
Therefore, some related issues were studied in this paper by experiments, theoretical calculation and engineering practice.
There are different ways to achieve this purpose, such as enhancing the quality and strength of anchor, selecting supporting anchor for different wall materials, using glass fiber mesh between anchor and rock wool board, etc.
Engineering practice Energy efficiency in the existing building 317# of Huizhongli community in Beijing is the first pilot project according to local standard, Design Standard for Energy Efficiency of Residential Buildings (DB11/891-2012).
Some methods would provide support for this purpose, such as enhanced quality of anchor, suitable anchor for substrate materials, glass fiber mesh between anchor and rock wool board.

Nuclear power plant engineering quality is the security of nuclear safety.
The construction engineering of conventional island and BOP engineering should reference the "quality inspection plan" of the thermal power engineering. (2) Based on the process, combined with the existing technical data, set the W//H bit design acceptance record.
The materials and key data acceptance are the focus of this work

However, alloys with C content higher than 0.16wt.% reacted with the ceramic materials.
The selection of ceramic mould materials as well as the interactions between melt superalloy and the ceramic materials are both key factors that affect the surface quality of the superalloy components.

The study of hydro-thermal-mechanical process coupling in unsaturated porous material is very important due to its close relationship with environmental geomechanics engineering.
Geotechnical material is one of the most widely used porous materials.
Nowadays, many programs prevail, but they are not able to do an accurate numerical analysis on the engineering structure of porous material under saturated or unsaturated conditions.
Recently, the program developed by Padua University, Italy for the hydro-thermal-mechanical analysis of porous material (COMES-GEO) can well solve these engineering problems.
