In China, a 20-year exposure program of various materials was started in 1984.
A national network was organized under the National Science and Technology Commission and National Natural Science Foundation of China to carry out the program [13].
Corrosion data can be obtained from the Test Station of Atmospheric Corrosion which includes corrosion rates of different kinds of materials at different exposure time.

A feature of this thermoplastic PI is its ability to controlled crystallization and recrystallization, which has been repeatedly shown on the example of films and binders for composite materials [9-11].
The fibers were formed from a solution of PAA by the wet method at the PIFV-01 installation (Institute of Macromolecular Compounds, Russian Academy of Sciences).
The material is stable up to a temperature of ~ 490 °C (the temperature of loss of 5 % sample mass) (see table 2).

Application of Artificial Wetland Technology in Rural Water Pollution Control Huanying Zhu1,a, Ming Zhou1,b, Xiao Liu1,c 1Faculty of Civil Engineering, Kunming University of Science and Technology, Kunming, 650500, China aEmail:1151558287@qq.com, bEmail:591731298@qq.com, cEmail:7815160@qq.com Keywords: Ecological wetland; Water Purification Technology; Rural sewage Abstract: In recent years, with the quickening pace of urbanization in our country, rural economic development and living standards have greatly improved, however, at the same time, economic development also makes the rural water environment increasingly serious.
Discharge of sewage are mainly composed of villagers living sewage, its characteristic is: the scattered distribution, high organic matter content, good biochemical characters, low content of poisonous and harmful material, large fluctuations of water quality and quantity and so on[1]. 1.2 The current collection methods Due to imperfect drainage facilities in rural areas, far away from the city drainage system, high cost of investment of the drainage pipe network system, and the difficulty of sewage collection and treatment, so, its sewage collection mode should take full account of favorable conditions locally available, adopting the method of combination of centralized collection and decentralized processing.

Gold Nanoparticle’S Temperature Effect In Photoacoustic Tomography Jian Rong1a, Lin Huang1, Lixin Liu1, Kui Lu1, Bingzhang Chen1, Xiaochun Zhong2 1School of Physical Electronic, University of Electronic Science and Technology of China, China 2School of Physical Science and Technology, Southwest Jiaotong University, Chengdu, China a e-mail: rongjmail@163.com Keywords: gold nanoparticles, temperature effect, Photoacoustic tomography Abstract.
For further simply our model, we just consider the heating of the nanoparticle occurs below the temperature of phase transition in the particle material, so we can neglect the last term of (8),besides, and f (t) [16] are too small to be considered, so we got(5)for the simulation: (8) duration is too small, we use delta function stand for its time term, and we have, employ the method which used in (2), we still have, because we focused on spherical symmetry situation, we confined our PA pressure – temperature effect simulation on the x positive axis and let other variable temperature independent simultaneously.
