Take HeBei Normal University of Science and Technology as an example, the number of students in an English class can reach as much as 80, or even more.
In the web-based learning environment, they can work out their own study plan, set goals for themselves, choose appropriate materials.
While when they are confronted with the large amount of material alone, they have no idea how to choose.
Not only can they use internet to search learning material, but they are also easily attracted by things that has noting to do with their study.

Introduction In recent years, with the increase in demands for global environmental conservation, green or environment-friendly materials are being actively developed.
However, as the materials with low surface tension such as resin materials have a good wetting and spreading characteristics on the surface of both metal and resin, it has been known that it is impossible to obtain the self-alignment capability with them.
Material properties of resin materials diluted with BCA (Butyl Carbitol Acetate) were shown in Table 1.
Generally, the liquid resin materials have considerably high viscosity (several Pa⋅s ~ several hundred Pa⋅s) comparing that of molten solder (about ��× 10-3 Pa⋅s).

The main contents are based on science and technology, but these have been developed and implemented by the young students of the college.
Using the steps and the process, students can start to make a real 2D codes with various materials.
They started the preparation of collecting materials and devices (magnets, projectors and so on).
In this activity, requested skills are how to make a Data Matrix in some useful material and/or media.
Through the project year, the teaching materials has been considered and developed for the students who learn the technology of image processing for the tag code inspections.

For materials characterisation there are only a few non-destructive techniques available to analyse these properties.

The first research and developments were mostly concerned with low melting point materials such as aluminum or magnesium alloys and focused on the rheology of materials in the semi-solid condition [5-8].
Only recently has there been a significant interest in the study of thixoforming of highmelting point materials such as steel [9, 10].
Many studies on low melting point materials have demonstrated the influence of holding time on microstructure morphology [55,62-65].
Thermal effects, considered of lesser importance for low melting materials, are essential in thixoforming of steel.

With the proposed method, it is possible to solve crack propagation problem in heterogeneous materials with plastic inclusions with enhanced work-of-fracture of the material.
Hamiltonian Construction An elastic material with a linear crack inside the material was considered.
Summary The Hamiltonian approach made it possible to analyze crack’s propagation in heterogeneous materials visually with minimal use of mathematical tools.

Introduction Some researchers have already focused on finding alternative supplementary materials in new times, keeping in mind the grave consequences of using chemical admixtures indiscriminately.
The hunt for such additional cementitious materials should lead to worldwide sustainable growth with the least amount of environmental impact possible.
A variety of studies are currently underway to determine the impact of using these pozzolanic materials as cement substitutes, and the findings are promising.

Municipal domestic waste contains large amounts of recyclable materials.
The main cost of production calculating: The prime cost and expense of cleaning the granulation include: the cost of raw materials and other related expenses (labor costs, loss, electric charge, cleaning agent fee, taxes) (1) Material costs: the raw materials of granulation are mainly old plastic bags and woven bags, their main component is polypropylene.
