In this kind of repetition of teaching, develops the inertia of learning, learning effect is obvious. 1.4 Teaching environment Started relatively late compared to Japanese hotel English, fewer students, learning materials and examination guidance related to materials are not easy to collect.
Conform to the teaching purpose, have higher scientific teaching materials will have crucial significance to improve the teaching quality.
Can try to replace other teaching materials, such as "everyone's Japanese" can be as the main body of the first three semester teaching material, the teaching material of both the detailed patterns and syntax parsing, and pay attention to the corresponding practice and the applicability of the conversation.
Also appropriate into Japanese folk culture and other related materials, to enhance the students' interests, broaden the horizons of students.

Introduction Magneto rheological fluid is a new branch of the magneto rheological smart materials, which has attracted increasing attention of researchers.
The research in magneto-rheological materials started relatively late in China.
At the same time, the technology of preparing Ni was short of simple and convenient, which needed to be refined from toxic raw materials.
In the early 1930s, the most typical preparation method of iron powder was the chemical reduction method, which used mill scale or super finishing powder as raw materials.

And they also expect these materials be used in the engine structures of transport machines such as automobile and plane.
In recent years, materials investigators have manufactured some low-cost Al-matrix composites [3,4].
Materials and experimental technique Materials selection and composite preparation The matrix materials used in this work were 6063 Al alloy.
The reinforcement materials were Al2O3·SiO2 particles having been pretreated.

The first commercial w-LED was generated by combing an InGaN-based blue diode and Y3Al5O12:Ce3+ (YAG:Ce) yellow phosphor materials [5].
The raw materials were Na2CO3 (A.R.), SrCO3 (A.R.), (NH4)2HPO4 (A.R.), and Eu2O3 (99.999%).
The stoichimetric amounts of the raw materials were thoroughly mixed and heated for 5 h in the air atmosphere at 1100 oC to get phosphor samples.

Recently, with the increasing demands of light weight materials in application, magnesium and its alloy have been widely applied in many important industrial fields, such as aerospace, automobile, computers, mobile communication, etc., and known as a high performance material having great application potential in the 21 century.
However, magnesium is close-packed hexagonal structure with a small number of slip systems, the number of slip system has a profound influence on the plasticity of metallic materials and more slip systems indicate superior plasticity.
High pressure is known to influence electronic structure and crystal packing, and play an important role in materials properties, such as phase trasition[6-8].
