For cathode material, LiCoO2 has been widely used in commercially lithium-ion battery.
For anode material, graphite have commonly used in commercial lithium ion battery using liquid electrolyte.
Another candidate for anode material is metallic lithium that has higher capacity around 10 times then graphite materials [2].
Chemical reaction in cathode and anode during the charging and discharging process is as follows: Cathode : Li1-xFePO4 + xLi+ + xe- « LiFePO4 Anode : LiC6 « Li+ + e- + 6C Experiment Materials used in our experiment consist of TMSPMA (Sigma-Aldrich), PEO (Sigma-Aldrich), chloroform (p.a.

The last but not the least, implements the major management for construction material of the supervised engineering according to the development of architectural market situation; organize an inspection for the sealed samples; the sealed sample shall not be less than 10 groups at once, mainly spot check that the strength of concrete in bearing structure, the strength of mortar in bearing structure, tensioned, welded and mechanical connected reinforcement joint in bearing structure, waterproof material of underground and roof, outer door window and energy-saving insulation materials, and the major building materials refer to structurally safe and practical function, then fill into and check relevant charts of 7 species the above according to demands. 2.2 Legislation of supervision conduction process Government supervision in construction quality process, which is a process of specialized agency commissioned by government implement law enforcement supervision for quality of construct Construction
It both includes components of monitoring documents are fixed, and includes monitoring documents are recorded with the same format[8]; there is the responsible person who record monitoring documents as well as the code reviewer for acceptance of materials and the manager for monitoring files; Realize standardization of supervision process by regulating the whole of process of monitoring documents. 3 Conclusions Standardization of government supervision in construction quality is composed of two major systems including the standardization system of supervision process and the standardization system of supervision decision.

Introduction Shape memory alloys (SMAs) have the ability to perform both sensing and actuating functions and have consequently been identified as potential materials for various functions within turbo-engines components.
The introduction of this category of materials in aerospace gas turbines however requires SMAs with martensitic transformation (MT) temperature above 250°C, which is well over MT temperatures of commercially available materials.

Zhang Shou-bao and Scotl AM [6-7] point out that the test model and the prototype structure need to be similar on the following aspects: the physical mechanics, geometrical size, the stress-strain relationship between the model and the prototype materials, the mass and gravity and the initial and boundary conditions.
However, even if the strength of concrete can meet such similar relationship, it’s hard to find the model materials that its section and intensity satisfy the similar relationship of the geometry and materials to simulate the steel of the prototype structure.
If the geometric similarity ratio of the scaled model is too small to cause the difficulties in construction, there is still a way to find alternative materials to ignore the influence of the mortar in the precondition of the similarity of the wall strength.
