Boron-based materials have an attractive property of high melting point, high hardness, antiwear, corrosion resistance, excellent electrical conductivity and anti-metal fusion to be the candidate materials for surface engineering materials.
Surface engineering materials also have the usage of electrofacing, chemical plating, and special chemical heat treatment process.
The future tendency of boron-based surface engineering materials will focus on the enhancement of compression coefficient, optimization of boronizing methods. 1.2 Boron additives.
The attractive physical and mechanical properties of boride cermets materials can be used as the candidate materials in aerospace, military, automotive.

The gap width of the sieve is usually similar to or slightly larger average size with processing materials.
Scraper is the main components of driving materials in the centrifuge, in most cases, scraper is perpendicular to the sieve and the drum, so that in the process of pushing materials scraper has great friction with materials, if their change the form of vertical sieve or drum with a certain angle, then from the mechanical analysis, the friction with the contact surface decrease obviously.

China nami_zhu@yahoo.cn Key words: secondary vocational education; science & engineering profession; effective educational model; effective teaching method Abstract.
The proportion of students opened physics course in secondary vocational schools’ science &engineering majors is so low, which has beyond our predictions.
Lots of special training of senior mechanic talent of secondary vocational school of science &engineering major has its necessity, physics as a basic course in science & engineering department, which plays an irreplaceable role in making the students to grasp the professional skills and improve overall quality aspect.
This requests us reform of our current teaching materials, reform our teaching mode and teaching methodology, thoroughly change the traditional education idea, set up the physics course should and must service for the professional’s thought, must learn professional knowledge in the process of teaching, dig deeperly into physics and taught professional correlation.
Only in this way, physics teaching as the basic knowledge can be coruscating vitality, make our science & engineering vocational education level to reach a new stage.

The applications of a new material used in controlling underground engineering and coal mine disaster have been introduced.
