Analysis of new materials of computer memory Zheng Qiuju Harbin Finance University, Harbin, Heilongjiang, 150000 Keywords: external memory; phase change memory; magnetic materials; crystal form materials Abstract: Modern computer memory, in addition to cache memory, is mainly divided into two categories: internal memory and external memory.
In this paper, based on a lot of information the author makes a brief analysis of the new material of the external memory, that is, the phase change storage materials, titanium oxide crystals form materials, magnetic materials and organic ferroelectric materials, and comprehensively promote the new research and new development of computer storage materials.
New phase-change memory and the improvement of materials 1-1.
The Ge2Sb2Te5 (GST) phase change materials research has more than 20 years of time.
In short, Ge2Sb2Te5 is the most ideal materials found for phase change.

Meng, X[5] classified material as raw material, semi-finished product and finished product.

Summary The even nucleation strain of materials may be determined by using the tensile experiment.
The damage process of materials may be more accurately simulated by using the volume fraction of initial materials holes and the mean strain of nucleation.

A HISTORY OF THE FRACTOGRAPHY OF BRITTLE MATERIALS George D.
Quinn Ceramics Division, National Institute of Standards and Technology, Gaithersburg, MD 29899, USA george.quinn@nist.gov Keywords: Brittle Materials, Ceramics, Failure Analysis, Fractography, Fracture, Glasses, History, Microscopy Abstract: The evolution of the science of fractography of brittle materials initially was driven by failure analysis problems.
While the fractographers were documenting their findings, there were some important developments in materials science and mechanics fields.
One of the most influential brittle materials fractographers, Prof.

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.
Suggestions on materials science professional English teaching reform Innovative theoretical classroom teaching methods.Rich course content, teaching materials increased novelty and fun.
Teaching materials need to be adjusted [6].Currently, some English textbooks specialized polymer materials is related to the choice of professional science books, professionalism lacking; Some textbook selection is "Fundamentals of Materials Science" in English or English translation of the original, is a disguised form of professional materials, students and too difficult to learn.
Summary Professional English is a materials science materials in an important professional courses, students actually crucial to the ability to use English.
