Combined with the piezoelectric equation of piezoelectric ceramic [10] and when applied electric field, the electric displacement is as follows: (1) Where is the electric displacement, is the piezoelectric coefficient of piezoelectric materials, is the average strain, is the dielectric coefficient of piezoelectric materials.
The basic material is copper, can reduce the residual stress.
The piezoelectric material of PCB is selected SOLID5 [12, 13], the primary material is selected SOLID45; Two kinds of PCB apply a force of 0.1N.

But it’s easier to find, in addition to the project the formulation, declaration, bidding and tendering stage mainly in the form of electronic data storage, a large number of materials and data exist in paper in other phases such as supervision of construction stage (Meng, 2006).
Meanwhile, it is not hard to find, paper materials as a traditional way of data storage are scientific and give a lot of negative effects brought by the engineering practice.
It reflects in five aspects: (1) Data sharing is poor, query and repeat utilization rate is low; (2) The management and storage of paper materials need a large amount of manpower and resource waste; (3) Occupied space is very big; (4) The life cycle of paper materials is shorter than electronic documents; (5) For the engineering quality supervision did not play a proper role.

For the large gear, the material was middle carbon steel (quenching and tempering) with hardness 240HBS.
The small gears material was middle carbon steel (quenching and tempering) with hardness 200HBS.
It is significant in saving material, improving productivity, decreasing manufacturing cost and increasing parts quality.

Stainless heat pipes were made of three kinds of materials AISI 304, AISI 310, AISI 316 and filled with a distilled water, up to 20% of the heat pipe inner volume.
The best results of heat pipe from treated materials was then measured at different inclination (0 ° - 90 °), at a temperature 90 °C.
In this article were presented heat pipes made of following materials: AISI 304, 310 and 316.
Can be concluded, that investigated materials had a negligible effect on the performance of heat pipes.
