In semiconductor industry, front-end processing consists of a multiple-step sequence of photographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material.
These processing environments are usually associated with high temperature and toxic chemical materials, in which humans are unlikely to stay and carry out any operation.

Most of these geosynthetics are by high-pressure polyethylene or polyvinyl chloride as the materials, taking several centuries to decompose gradually, and it will destroy the soil fertility and pollute groundwater, etc, left a serious hazard to the environment.
Though a lot of investigations on already existing ecological slope protection technology, try to study on replacing the full degradable bio-materials by commonly used geosynthetics, and form a more complete new technology of Bio-engineering protection of slope

These researches were all for isotropic materials, and the application was in fretting fatigue only.
The material parameters of other orientations are shown in reference[12].
So the contact stress can be decreased to lower than the yield stress of the materials.

Introduction Lanthanide trivalent ions are effective for luminescent materials because of their excellent quantum efficiency.
In this research group, an europium complex with a dihydroxy derivative of trans-1,2-dipyridylthene, α- pyridoin, and containing oxygen and nitrogen donating atoms is prepared and tested for the possible electroluminescent materials.

And it has been in continuous progress and perfection, with the development of society and the progress of science and technology, the dynamic characteristic is being strengthened constantly; On the other hand, as a specific commitment of university engineering undergraduate teaching practice, a professional teacher’s theoretical knowledge, knowledge structure, ability and means reflected more changes in teaching behavior.
As a professional teacher, must pay attention to and strengthen the scientific research work, absorbing materials, results from others, the innovation of research results, and its application in teaching practice.
In the teaching practice of undergraduate major in engineering, the success or failure, the quality of engineering undergraduate education and training largely depends on the knowledge structure of the professional teachers, especially in science and technology combining with each other today, this point seems keep more special significance.
