Some of these materials belong to the group of AHS steels, are characterized by the twinning induced plasticity (TWIP) effect which is a new type of steel possessing together with high strength a great plastic elongation, and an ideal uniform work hardening behavior.
Moreover, the procedure of materials selection for automotive industry requires tests of mechanical properties as a function of strain rate, because at high strain velocity, typical for a car crash, mechanical strength is substantially changed [1, 2, 5, 6, 12, 13].

These materials are encased inside a stainless steel tube to ensure the durability.
In previous experiments, we attempted to connect all materials in one step.
The surfaces of the materials were connected under observation through a microscope.
Second step is adhering coupled materials and optical fibers.
We placed and adhered these materials with observing the microscope.

Quantitative analysis on steel framed roof’s temperature effect Jieying Xiaoa, Liuxi Yu b , Na Ji and Xing Li Pollution Prevention Biotechnology Laboratory of Hebei Province, School of Environmental Science and Engineering, Hebei University of Science and Technology, Shijiazhuang 050018 China a xiaojieying@hebust.edu.cn, byuliuxi9@163.com, Keywords: Steel Framed Roof (SFR), Land Surface Temperature (LST), Remote Sensing Abstract.
Among all kinds of underlaying surfaces, steel framed roof, as a kind of widely used building material, was found playing an important role on contribution to warm regional thermal environment.
SFR’s warming ability is stronger than any other roofing material[4], so analysis of the relationship between SFR and LST is very essential.

Fragrance materials generally compose of organic ester and various alcohols.
As in the processing, rubber materials must experienced heat not only in mixing step but also in the vulcanization step.
And for the final product, this carrier should be able to control the releasing rate of fragrance materials.
In organic carrier was found suitable for carrying fragrance materials.
