Hydrogen: Technologies, Policies and Challenges Zhang Jun1, a* Ji Lucheng2, b Jin Bo1, c 1Department of Energy Information Research, Wuhan Documentation and Information Center of Chinese Academy of Sciences, China 2School of Aerospace Engineering, Beijing Institute of Technology, China azhangjun@mail.whlib.ac.cn, bjilc@bit.edu.cn, cjinb@mail.whlib.ac.cn Corresponding author: zhangjun@mail.whlib.ac.cn, +86 27 87314525 Keywords: hydrogen, hydrogen economy, fuel cell, r&d, policy, technology Abstract.
From the perspective of United States’ technological funding decision-making mechanism, this was not solely Obama’s individual will, but also results from the prospect analysis of engineering and scale applications of hydrogen energy technologies and the review of the hydrogen economy.
In the National Medium and Long Term Program for Science and Technology Development (2006-2020) and the Energy Development Eleventh Five-Year Plan, the hydrogen energy is emphasized as one of the key advanced technologies.
Challenges for Hydrogen Economy Hydrogen energy has its advantages, but there are also many big challenges in science, engineering, economy and politics.

TOPAS macros are provided and the results compared with analogous modelling performed according to advanced analysis methods such as the Whole Powder Pattern Modelling.
Whole Powder Pattern Modelling [4] is one of the most advanced methods for microstructure analysis using powder diffraction techniques.
The TOPAS macro language allows fast and effective models to be implemented for the analysis of both monodispersed and polydispersed systems, providing results that in the most simple cases are compatible with the more advanced Whole Powder Pattern Modelling techniques of microstructure analysis.

Thermodynamic Research on Solution Properties of Al-Er Alloys Chunyao ZHAN , Wei WANG, Zhenlei TANG, Zuoren NIE* College of Materials Science and Engineering, Beijing University of Technology Beijing 100020 China Corresponding author*: email: zrnie@bjut.edu.cn Keywords: Al-Er Alloy; Miedema Model ; Interaction Parameter; Activity ; Excess Gibbs Energy Abstract: Mixing enthalpy of Al-Er binary alloys system has been calculated based on Miedema model, in which a new interaction parameters Li proposed by George Kaptay was considered: Li=h0i.exp(-T/τ0i ), which are used to indirectly calculate the activity of Er in Al-Er alloys and some other thermodynamic properties, such as excess Gibbs energy and excess entropy at 1073K.
Since the first report about the addition of rare earth element Er improving the anti-corrosion of Al-Mg alloys by Rosalbino F [4] in 2003, many experts have been tried to do a lot of advanced researches on phase transformation mechanism of Al alloy with minor Er.

Teaching methods, assessment methods single.Currently the Teaching of English vocabulary commonly used to explain, reading professional literature, translation patterns, some teachers even professional English lesson positioned "Advanced English reading," although this mode of teaching can improve students' reading professional literature to some extent professional competence and mastery of vocabulary, but ignored the students' practical ability to use English training, and cannot mobilize students to participate in classroom enthusiasm and initiative, thus reducing the effects of teaching.For the assessment of the way the course is more simple, more than a simple written test, written mostly content to include only words and sentences (or paragraphs) of Translation, lack of listening, speaking, writing and other practical application of English proficiency assessment [3].
Browse existing "Materials Science and Engineering English" shows that the majority of the content is "Introduction to Materials Science" or "Fundamentals of Materials Science" in English translation, can be said to disguise course books.
Materials selection can not both versatility and professionalism.Many specialized polymer materials in English textbooks, but with less specialized polymer materials related to the textile and engineering, so the choice of professional and highly versatile materials more difficult [4].
