Introduction The most commonly materials used for resistance thermometry at low temperature are carbon, platinum and germanium resistors.
Of all materials currently utilized in fabrication thermometry elements, platinum has the optimum characteristics for service over a wide temperature range.

In the selection of material constituents and mixture proportioning of SCC for precast and prestressed structural elements, it is essential that the concrete should be self-consolidating, i.e. it should flow into place and encapsulate the prestressing strands and reinforcing bars without segregation or blockage.

The longer calendar time the aircraft structure serves for, the more seriously the structural fatigue quality will be debased because of corrosive environments, and the corresponding actual fatigue life value of aircraft structure will be shorter; at the same time, the fatigue loads of aircraft structure can accelerate the invalidation of the surface anticorrosive coating of components of aircraft structure and promote the corrosion of parent materials.
After obtaining the value of Nf0, based on the corresponding materials and stress characteristics which influence an aircraft structural service life, simulated tests (specimen level tests) should be carried out on these dangerous positions.

Introduction Pipelines, used as transmission paths of materials and energy, have been widely applied in industrial productions such as petroleum industry and chemical engineering industry.
In order to facilitate the vibration analysis of the whole machine, the appointed materials and their stiffness, density and mechanical properties need to be defined.
