Historic Retrospection and Present status of Severe Plastic Deformation in China Jing Tao Wang School of Materials Science and Engineering, Nanjing University of Science and Technology Nanjing 210094, P.R.
SPD is becoming a hotspot in materials field in China.
Introduction It is well recognized that the interrelationship among the four components of composition, processing, structure and property, composed the nucleus of the discipline of materials science and engineering.
Recently, however, world wide great progress and achievement in research and development concerning severe plastic deformation and related materials, claims the dominant role of high strain in the control of materials microstructure, and attracts ever-increasing sight of the materials experts world wide [1].

Is electronic materials really helpful for the development of learners’ autonomous abilities?
The questions of the questionnaire focused on the learners’ use of electronic materials, the influence of electronic materials on learners’ foreign language learning and the learners’ attitude towards electronic materials.
And the functions and impacts of electronic materials based on information system on learners’ autonomous autonomous abilities of learning are mainly listed as follows: First, electronic materials are just a kind of useful learning tool.

Optical differentiation method of materials based on the modeling of scattering characteristics Shixue Xu1, a, Lingfei Xu2,b, Yanru Chen3,c 1,2,3Department of Optical Engineering, Nanjing University of Science and Technology, Nanjing, P.R.China 210094 aete_corner@yahoo.com.cn, bjsj900@hotmail.com, cyrchen2002@yahoo.com.cn Keywords: Scattering, material differentiation, modeling Abstract.
We also try to modeling the characteristics of materials scattered light in order to recognize or distinguish given materials in detection.
The reflectivity of materials determines the intensity of scattered light.
Our research indicates that the optical differentiation of materials method will have more feasibility if we take more information from the scattered light of materials’ surfaces.

For journal publishers, no matter publishing in what kind of media, the first thing is to determine the theme together with the readers, and then plan how to find and collect relevant materials, and then refine, recompose and beautify the materials, and try to attract readers.
It has become one of survival strategies of the journals.
Even so, the paper journals is not without any merits.
Traditional popular science journals’ coping strategy impacted by the Internet[J].
